Hi everyone! I'm a videographer who specializes mainly in real estate videography. One of the problems I run into is sharing videos with clients and getting paid in a timely manner. It's a hassle emailing Youtube links to share videos with clients, sending Dropbox folders for them to download the video files and using Paypal to invoice clients, only to have to manually remind them if they are slow to pay. This led my brother and I to develop a platform, through our company Airilo, that allows videographers to automatically share videos with clients after they upload them and allows clients to download the videos only after they have paid for them. With this software, we aim to provide a complete solution for client interaction, video delivery and billing, allowing videographers to focus on what they do best: providing stunning videos. We just finished developing the software and are now looking for beta testers. In this round of beta testing, our beta testers will work with us to identify any bugs in the software as well as provide feedback on which features we will need to add to make Airilo Connect ready for market. If anyone would like to be a beta tester please fill out this survey: https://www.surveymonkey.com/r/XG2XSG5 More information can be found on our website at: airilo.com/connect. I'd love to hear if anyone else has had a similar problem.
OK, so I have my Part 107 certificate and I have the Drone Pilot Ground School certificate, I must be finished with UAV Coach, right? Not so fast. I just finished the last of the BONUS interviews that are provided as part of the Drone Pilot Ground School. The information there is really incredible! There is a goldmine of knowledge and information in those interviews. So, for anyone who is taking this course or has completed the course and obtained their Part 107 certification, I think it is very important that you finish the course and listen to each one of the interviews. I've listed them here even though they are clearly marked at the end of the course lecture listings. Ask a Drone Lawyer: Key Legal Considerations for Starting a Drone Business (32:26) Using Drones To Do Real Estate Marketing Understanding Drone Liability & Hull Insurance (22:27) Transitioning From Part-TIme to Full-Time Professional Aerial Services Running a Commercial Drone Program With Skyward (38:49) These are an important part of any drone pilot's education. Take advantage of them. The resources chosen to participate are top-notch indviduals as well. They know their business and they know what you will encounter in yours. Stan Nickel
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.
