  1. Good Afternoon Everyone, I recently launch a digital marketing agency that focuses solely on the golfing industry. One of the services I offer is hole-by-hole guided tours. I'm looking for an individual/team that lives in South Florida (Atlantic side of the state) to do contract work as part of my team. I posted this job on droners.io and was overwhelmed with the responses from all over the country. I unfortunately was not specific about the location of the individual/team, so I'm hoping to make that clear here, I just want Florida based licensed UAV/Drone operators. I really appreciate your time and please reach out if you have any questions/interested. I'll be in Boca Raton from May 1-11 and I'm looking to meet prior to agreeing to any terms. Thanks, Matthew Neumann
  2. Hello everyone! I'm Muhammad Waqas, student of Mechatronics Engineering from Islamabad, Pakistan. We're doing a project on UAVs and we need to make a flight controller board. So my question is pretty simple, can Raspberry Pi be used as a Flight Controller? How complex it is to code a flight controller? And is there an easy method to develop a flight controller of our own?
  3. Checkout this testcase for live video streaming from a UAV: http://uav200.com/experience/#ansur-nexus-II-aviator-uav200 Using ASMIRA from raidosystem.com the UAV can be flown with visual transmission even with very low bandwidth. A preview of the video takes can be delivered in real time concurrently to the "normal" live camera view for the pilot, thus you can see the footage while the bird is still airborne.

    Dear All, If you are worry about the UAV video transmission part, please contact me any time. Support: HD1080P image RS485 control signal 0ms delay 100KM flight distance live video
  5. UAVs or as many know and call them, “drones”, have become quite popular in the last couple of years and it seems that, nowadays, everyone has them. This is mostly because the market is over flooded with a plethora of cheap models, and you can buy a drone to have fun with in the back yard for less than $20. Of course, if you want a more sophisticated model that goes over 60mph, or has a 4K camera and basically, does the flying on its own, you will have to cash out from $400 and up. Is there a solution that offers all those great features, but for less money? Yes, there is and it’s called a DIY drone kit. Such a kit gives you a chance to own a great drone model that you can customize to your liking and learn about the drone technology, electronics, physics, aerodynamics, and much more as your project advances. Depending on which kit you choose, you can just order a frame and buy the rest of the parts separately, or you can choose a kit that includes almost all the parts and usually, you just need to buy a battery and a transmitter. Whichever type of a kit you choose, you first need to know how to choose the right one for you. How To Pick the Right DIY Drone Kit If you think that picking a DIY drone kit is easy peasy, you are way off course. You can’t just pick any kit and hope that the final product will be capable of doing what you intended it to. First, you need to decide what are you going to use the drone for. There are two basic types you can choose from: Freestyle drones (also known as racing drones) Aerial photography drones Racing Drones If you choose to go down the Racing path, you need to find a kit that includes a small, light, and durable racing frame, high KV value motors (KV stands for Rounds per Volt), and a Flight Controller that is suitable for that kind of flying. Why do we say a small racing frame that is durable and light? Well, a racing drone needs to be as light and durable as possible because you will crash it a lot, believe us. As for the motors, well, the higher the rounds per volt, the faster it will go and the faster you will be able to change the direction and perform breathtaking aerial stunts like flips, barrel rolls, loops, and so on. Our advice is to opt for motors that have 2300KV or a higher value. When it comes to a flight controller, you won’t actually need one that has all the fancy sensors that keep your drone leveled all the time, the GPS position assistance systems, the high precision barometer for keeping the altitude on its own, and the rest of the high-tech gizmos. You will want a package that gives you the ability to fly in the Acro mode (meaning you get to do all the flying without any assistance) and have the raw power. If you want to have the real drone racing feeling, then your kit also needs to support the onboard FPV (First Person View) equipment and that includes an FPV camera and an RF signal transmitter. (Racing drones usually have carbon fiber bodies and short propellors) Aerial Photography Drones If aerial filming and photography is your choice, then the drone kit you choose needs to be much more sophisticated than a racing drone kit. For starters, you will need a much bigger frame. Also, unlike for racing, where people use exclusively frames for 4 motors (quadcopters), when it comes to aerial filming, the more motors the better. You can choose a Hexacopter frame or even an Octocopter frame. As for motors, this time it’s reversed, the lower the KV value of a motor is, the more stable your drone will be and more filming equipment (camera and gimbal) it will be capable of lifting safely in the air. We suggest going from 900KV or lower. You also need bigger props. For example, if you choose 900KV motor, you should opt for a 10-inch prop. The lower the KV goes, the bigger props you will need if you want efficiency. When it comes to Flight Controllers, for this type of a drone, you will need as much assistance systems as possible. You want your drone to be stable and self-reliant as possible so that you can focus on filming and not so much on flying. If you want ease of setup and to be airborne as soon as possible, we suggest something like the DJI Naza series. If you want to program all the features yourself, you can choose something like the Pixhawk or APM flight controllers. But be warned, if you are not that familiar with programming and coding matter, we suggest going for the Naza series (M Lite or M V2). Important to know: Before choosing any type of DIY drone kit, make sure you know how to actually control a drone. Otherwise, you might get it all prepared for a flight, and crash it only after a few meters if something unexpected happens. Therefore, we suggest that you first buy a small, cheap drone to hone your piloting skills, and only then opt for a more serious drone kit that will get you deep into this hobby. If you want to read more about drone flying tips, we suggest checking out this How to Fly a Drone article. (Aerial photography drones have wider bodies and longer propellors to stabilize their cameras) How to Use a Drone Kit Using a drone kit is pretty much like building a drone from scratch, only, in this case, you don’t have to build the frame from scratch, as you get the frame in parts and you only have to follow the instructions to assemble it with bolts. As for the rest of the parts, depending on what is included in your kit, the procedure is the same as with other DIY UAV projects. After assembling the frame, you need to add ESC’s and motors, connect them properly (check the ESC’s and motor rotation). To connect the motors and ESC’s, we suggest using bullet connectors and heat shrink tubing for isolation. Then, you have to solder the ESCs to the power distribution board, (but most frames today come with an integrated power distribution board so you will probably just have to solder the ESC wires to marked spots on the frame). After that, you need to place your flight controller, but you need to be careful where you place it on the frame because if it’s not directly in the center, your controller might have glitches that can cause your bird to crash or even worse, simply fly away. Also, you need to find the perfect spot for your RC receiver (and the FPV transmitter if you decide to fly in FPV), as far as possible from the GPS module and the flight controller, to avoid interference. The same goes for the GPS module, you need to find the center position for it, but don’t worry, with the help of Mr. Know-it-all (YouTube) you will get everything done quite easy because there are tons of tutorials there. However, if you want an in-depth tutorial on building your drone, we suggest that you check out our DIY Drone: How to Build Your First Quadcopter – Part one and Part two articles for every bit of information you will need for such a project. Wrapping It Up Now that you know how to pick the right DIY drone kit for your needs, and you are equipped with all the needed knowledge, the only step you have to do is to pick a kit. Happy building and don’t forget to let us know which kit you chose and how it went!
  6. Not to long ago I received my first airspace authorization after about 2 months. When I applied I submitted to applications, one for airspace authorization in Class D Airspace with 90 days out, as I had a flexible client.. And another for a job that I would lose unless I could get the authorization within 30 days. The one I submitted for 30 days was denied based on the timeframe. The one I submitted for 90 days was approve. I'm curious the way you guys are approaching requesting authorizations that you need before the 90 days. Can I assume that any request with a start date within 90 days will be denied? I have shoots that I need to get done asap, but I'm worried If I fill out the application with a start date sooner than 90 days it will get denied. Has anyone been approved for authorizations with start dates sooner than 90 days out? If so, how did you determine your start date? Any advice on submitting applications for authorizations for projects that are flexible on exact dates but generally time sensitive (the sooner scheduled the better) would be great.
  7. New Member

    Hi Everyone, I am Prince and I am from Ghana and i happy to be part of this wonderful community. DJI Phantom4 Pro is what i use. Hope to learn more from here.
  8. Hello everyone! I have created a software package that -amongst other purposes- it can be used to compensate for rolling shutter artifacts and provide corrected images. The overall scope is to increase the accuracy on 3D models created with photographs captured by Phantoms or other low cost UAVs and/or cameras. From tests that I have performed so far, the accuracy increases up to 70% for fast flights. I am turning to you now to further test my algorithm. If you have UAV-captured datasets that you can share with me, I would be very grateful. The only restriction is that I need datasets that have GCPs measured with RTK to eliminate this error source. Thank you very much in advance!
  9. Hi, I'm Ronnel Patubo graduate of BS Computer Engineering at Polytechnic University of the Philippines. I am new to drones and UAV's. I just want to learn more about my hobby then find a friend or mentor. And someday become a professional in building Drones. Regards, Ronnel

  13. UAS College of Choice

    Hi guys, I'm a newly interested UAS drone pilot looking for a school to pick from in terms of preparing myself for the industry. Right now I am torn between UND and Oklahoma State. UND is a leader when it comes to training pilots and offers a major in UAS (however it only focuses on flying and not engineering or design in uas), they are also pretty cheap when it comes to overall cost. Oklahoma on the other hand offers a graduate program that focuses on UAS engineering. What I am torn on is the decision about whether to completely forgo my backup plan to be a professional pilot and enter the drone industry through the engineering aspect of things, or should I keep the commercial pilot idea in hand because of the shortage and just go through one of the drone pilot programs that focus on flight and not necessarily engineering or design? Anybody who has experience in the field or at one of these universities would offer me huge help, thanks.
  14. Tarot 680 Build

    Hello everyone! I am undergoing a new build using the Tarot 680 Pro frame as my base....however I ordered the Tarot Iron Man 680 kit instead of the 680 Pro kit. Does anyone know if I can just swap the center boards/integrated PCB board from the 680 Pro kit with the stock Iron Man 680 kit? That way I don't have to buy a second kit. Secondly, has anyone had experience using a Canon S110 or S120? I'm planning on using this as my imaging sensor. Finally, does anyone know where to find inexpensive gimbals or gimbal kits that will support the size of an S110/120 or any other digital camera for that matter? I greatly appreciate the help in advance!! -Cody

    Hi, Anyone out there knows how to kick start matlab code for Swarm UAV Algorithm?
  16. UAV Insurance Broker

    Are you thinking about becoming a commercial UAV pilot under FAA part 107? If so, UAV insurance should be a main concern of your new business. A vast majority of "standard" liability insurance policies exclude anything that has to do with aircraft. Since UAVs are under the purview of the FAA, they are considered to be aircraft by most insurers. So how do you get your new UAV operation insured? Easy, contact an aviation specific insurance broker (I happen to be one). If this sounds intimating, you are not alone. However, once you understand the basics of insuring an aircraft, you will be an aviation insurance wizard. The base policy in the aviation insurance industry is liability only. The limits on liability only policies range from $500,000 each occurrence all the way up to $5,000,000 each occurrence. However, if higher limits are needed, they can be negotiated. This liability coverage will protect you from any Bodily Injury or Property Damage claims that may arise from your operation of your insured UAV(s). Fly through a window while shooting a real estate video and land on somebody's grand piano? Covered. Hit a passerby and cut their finger? Covered. After you have purchased liability coverage, and are looking for more protection, you can then add "hull" coverage to your policy with some of the aviation insurance companies. Hull coverage is physical damage to your UAV itself. This is a "Stated" or "Agreed" value. Let us say you have a basic DJI Phantom 3 Professional that you have insured for $1000. You slam this aircraft into a tree and completely destroy it. The insurance company takes a look, sees that it will not be feasible to repair it, and they deem it a total loss. In this scenario, you would get a check for $1000 minus any applicable deductibles ( UAV deductibles are usually 5% - 10% of the insured value of the aircraft). Same logic applies to any other UAV. However, if you have an inspire 1, with a very expensive upgraded camera, you would want to "schedule" the aircraft and the camera separately. The upgraded camera can be added to most UAV insurance policies as "payload" equipment. Liability and Hull coverage are the main coverages that you should be concerned with as a commercial UAV operator. There are some other "ancillary" coverages that I will address in future posts. Thanks, Joe Ernster Bullock Agency, Inc. joe@bullockagency.com

  18. Succesfull Acceptance Test Procedure (ATP) in Israel

    Located at the Volcani Center campus in Bet-Dagan, near Tel-Aviv, Agricultural Research Organization (ARO) six institutes are responsible for Plant Sciences, Animal Science, Plant Protection, Soil, Water and Environmental Sciences, Agricultural Engineering, and Postharvest and Food Sciences. ARO also operates four research stations, in various parts of the country, and serves as a testing center for agricultural produce and equipment. Israel's Gene Bank For Agricultural Crops is also located on the ARO Volcani Center campus. While encompassing the full range of agricultural research activities, ARO focuses in particular on arid zone agriculture, enabling Israel - a country short of all the resources required for agriculture - to achieve among the highest levels of agricultural output in the world. As an agricultural research center of international standing, ARO each year attracts a large number of groups from abroad, as well as numerous individual visitors. These include academics, heads of experimental stations, representatives of private companies and public officials. ARO maintains particularly close relations with the various international, regional and national institutes involved in the promotion of good agricultural practice and in the increase of agricultural output, and in particular with the U.N. Food and Agriculture Organization (FAO). At Alpha Unmanned Systems we have always believed that our UAV, the SNIPER, could be useful in improving agriculture. From the Volcani Institute they have proven us correct and by buying two of our drone helicopters they have placed themself at the forefront of agricultural innovation. Equipped with a Flir SC-655 infrared camera plus an on-board processing computer, with a 2 hours autonomous flight and a 2.5 Kg payload; both SNIPER units will support the ARO in their precision agriculture researches, with main topics such as hydric stress, diseases detection or soil nutrients optimization. Also we want to emphasize that we will be pioneers in achieving certification for civilian use of unmanned helicopter. Once delivered, corrected and accepted by the Israeli authority all communication systems and manuals, Alpha gave a training program in Spain, Madrid for two pilots of the ARO and two pilots recognized by the Israel Civil Aviation Authority (ICAA) so they can mentor new pilots in their homeland. After making the handover protocol we travelled to Israel, Tel-Aviv to finish the ATP with our client and perform the first flight tests required to achieve certification by the ICAA. The flights were realized at Tel-Gezer which is a well known area due to it's natural park and past history. All both ATP & ICAA requirements were carried out succesfully.
  19. The radio link range is one of the most important aspects in a UAV. How far can we go with a good radio link? What affects this distance? How to increase the link range? are usual questions that concerns to UAV developers and manufacturers. Well this are the main factors that will have influence while achieving the maximum possible distance: - Bandwidth: the rate of data transfer, bit rate or throughput, measured in bits per second (bit/s). - Transmitter power: is the actual amount of power (in watts) of radio frequency (RF) energy that a transmitter produces at its output. - Antenna gain: an antenna's power gain or simply gain is a key performance number which combines the antenna's directivity and electrical efficiency. Normally the higher the gain, the narrowest radiation patter, f.e. a omny antenna has typically 3 to 5 dBis while a patch antenna can have 9 to 18 dBi but the patch antenna like the used in the G-TRACK must be always aiming to the UAV to have good link quality. - Losses: connectors and cables reduces the final output power of the system as it has looses. - Receiver sensitivity: Is the minimum magnitud of input signal required for a good performance of the device. - Fade Margin: Is the minimum margin necessary to ensure a good communication link measured in dBi a desired fade margin is 20 dB. - Path Loss: The losses produced by the attenuation of the signal caused by the distance between the two radios. - System Gain: Final system transmiting power taking into consideration all the installation; is the sume of the following: Transmitter Power + (Transmitter Antenna Gain - Transmitter Cable and Connector Losses) + (Receiver Antenna Gain - Receiver Cable and Connector Losses) + | Receiver Sensitivity | The following example shows an estimation fo the distance that you can achieve using the PCM data link with both ground and air omny antennas: Tx power = 30dBm (equivalent to 1W) Tx antenna gain = 6dBi Tx cable/connector loss = 2dB (typical value for one meter coax cable) Rx antenna gain = 3dBi Rx cable/connector loss = 2dB Rx sensitivity = -108dBm System Gain = [30+(6-2)+(3-2)+108]dB = [30+4+1+108]dB = 143dB. Under this situation we can have maximum path loss of (System gain - Fade Margin) 143 - 20 = 123 dB that in the frequency of 2.4 Ghz is equivalent to 15 Km. A table that shows some Path Loss values can be found below. Distance (Km) Master Height (M) Remote Height (M) Path Loss (dB) 5 15 2.5 116.5 5 30 2.5 110.9 8 15 2.5 124.1 8 15 5 117.7 8 15 10 105 16 15 2.5 135.3 16 15 5 128.9 16 15 10 116.2 16 30 10 109.6 16 30 5 122.4 16 30 2.5 128.8
  20. You just acquired the Alpha Unmanned Systems Power Board (PB) to make your piston engine UAV more reliable thanks to the back up battery while reducing or eliminating the battery care task. But now, which brushless generator should you choose for your UAV? Wich are the right RPMs to achieve the voltage I need? If you made yourself this questions continue reading this article. First of all, we have good news for you, all electric engines can act as motors or as generators, this means that if you apply electric energy to the engine it will give you work, but if you apply work it will give you electricity! This means that any drone electric engine can be used as a generator thats why they can be found at very affordable prices. But let's focus on what's important. In brushless engines there is a constant that will give us the clue to calculate all the necessary parameters to integrate the Power Board (PB) in the UAV. This constant is the Kv, motor velocity constant or the back Electro Magnetic Force (EMF) constant, this value tells us the number of RPMs that will be achieved when applying a certain voltage and is a data that all the manufacturers will provide. Then, having this value and knowing that we need a minimum of 19 input volts to charge the backup battery and that the maximum allowable input voltaje is 30 volts, a nice voltage value to work with would be lets say 24 volts, now assuming that the typical rpms of the propeller of a Fixed Wing SUAS are 9000 rpms we have all the necessary data to define our brushless engine. RPMs = Kv X Voltaje 9000 = Kv X 24 --> Necessary Kv constant is: 375 But what happens if, for example, we can only find a 475 Kv engine, then we would need to increase the rpms of the brushless generator to achieve the same voltage, in that case we can use the transmission between the propeller shaft and the generator to increase the rpms as follows: Necessary rpms are: Kv X Voltaje --> 475 x 24 = 11400 Gears/Pulleys relationship must be: 11400/9000 = 1.26 this means that the generator gear or pulley must have 1.26 times the number of tooths of the one installed on the propeller shaft, f.e. 15 one and 12 the other (12 X 1.26 = 15.12). Now you have all necessary information to integrate your generator and Power Board on your UAV!
  21. Matrice 100 Questions

    Hello, I just discovered the Matrice 100 and there are some questions I’d like to ask: As far as I know, the Matrice 100 has additional expansion bays which allows me to add my own components and computing boards/microcontroller board. I want to add my own WIFI module, Depth Camera, Infrared Camera…etc. These components are to link with the microcontroller board while the board communicates with the Matrice 100. I’d like to ask: 1. Will the Matrice 100 be able to satisfy my needs? 2. If it can, what microcontroller board/ can meet my needs? Where can I buy it or does DJI sell it? 3. Which Depth Cameras & Infrared Cameras be able to link with a computing board? Does DJI sell this stuff? 4. If the Matice 100 doesn’t meet my needs, what kind of UAV will?
  22. I would love to get involved in this community and have read the introduction emails as well as will continue to read the material in these forums! Thank you for being around and I'm glad I joined a thriving community!
  23. Operation at class G airport

    I've been searching for an answer to the question of operating AT a class g public airport. I see a lot of info on flying nearby, but nothing on actually operating at one. I don't seem to see any restrictions from part 107, but does anyone have any practical experience or knowledge on this subject?
