    Personally I would go with the Toughbook. I was using an Apple device and it doesn't do well at all in the heat without and lot of babying. Another consideration is weight. I don't know how you operate but we have to pack stuff into remote and limited access sites occasionally and carrying a lot of equipment through the brush is a real pain. Finally, will it work with the aircraft you fly? Can you link it on the job site easily or is the process cumbersome. Last point: power consumption. I know everything has a battery that will work forever under adverse conditions....I've got a few of those too. The fact of the matter is heat and cold change all that and are you going to need a power source to run your stuff when the battery fails in 100°+ heat after two hours?

    The MMC GCS in the second picture group claims to be compatible with pix4 and other open source flight control. So I guess this won;t be a problem. But you do remind me of the battery for the GCS which can be heavy.

    I personally use a Toughbook to run my flight control software. It rugged, self-contained, sealed against the weather and fairly reasonable in price. Choosing a GCS based upon looks alone is really short-sighted. Without any specs for your above choices, no-one can offer an informed opinion that means anything.

    NO.1 

    UAV Factory’s off-the-shelf portable Ground Control Station (GCS) . It is described as a flexible and universal solution for controlling unmanned vehicles andpayloads. By using modular electronics compartment (MEC), application specific hardware can be quickly installed. The GCS can be configured to control unmanned aircraft vehicles (UAV), ground robots, bomb disposal robots, remotely operated vehicles (ROV) and other robotic devices. 

    Key Features

     Universal off-the-shelf ground control station
     Based on fully ruggedized Panasonic CF-31 Toughbook
     Integrated Toughbook docking station
     User dedicated modular electronics compartment with threaded mounting base
     Two, 50 W stabilized 12 V power outputs for electronics compartment
     A comprehensive set of connections: 2 serial (RS-232), 5 USB, 2 Ethernet, 1 video in, 1 VGA in (optional), 1 Microphone in, 1 Audio out,
    PCMCIA slot, HDMI
     Super bright 17” and 13” touch screen displays
     10-32 VDC input range
     Hot-swappable dual lithium batteries
     Intuitive power monitoring display (battery status, input voltage, internal temperature, power consumption)
     Over-voltage, over-current, reverse polarity, battery over-discharge protection
     User-serviceable fuses
     Removable Cordura bag for accessories
     Carry handles, wheels and shoulder strap for convenient transportation
     Ruggedized and lightweight design

    NO.2

    This is Etlas NEO II from MMC UAV. It features high integration, military-grade IP 54 ingress protection, and it combines all the functions of image transmission system, data transmission system, handheld remote, image display system, and industrial laptop.

    Key Features

     Combining all functions of image transmission system, data transmission system, handheld remote, image display system, and industrial laptop

     Equipped with Photon A10 transmission system that integrates high resolution image link with data control station for bidirectional transmission

     Adopts dual LCD screens with the upper one showing images and the lower one showing ground station system interface, with 1500 nit brightness screen

     It is resistant to water, dust and shock and able to work perfectly under difficult working environment such as dust or rainstorm

     4-hour battery life satisfies long-time operation

     It measures only 406*306*93mm and weighs only 8kg, which makes it quite portable and convenient for emergent outdoor flying operations

     It has an 8-kilometer transmission distance and can satisfy most needs for remote control and image display.

     It has multiple data connector ports which are adaptable with multi-rotor drones, fixed-wing drones, robots, industrial controller and monitoring gimbal, etc.

  3. We have read many news about fire caused by drone battery. Some of them are due to battery overcharing, when a LiPo battery is overcharged, the anode of the battery becomes plated with lithium metal and the cathode produces carbon dioxide. The pressure inside the battery rises as more gas is produced until the outer skin of the LiPo bursts and vents gas. LiPo venting is usually accompanied by flames which leads to the entire battery destroying itself. Overcharging can be prevented by charging LiPo batteries to a maximum of 4.2 volts per cell (or 4.35V for lithium high voltage packs) and charging at a safe current setting. 

    Some due to over discharging. When quickly discharged in situations such as a drone race, a LiPo battery will heat up. If excess current is drawn from the battery causing it to overheat, gasses will form inside the battery. Like overcharging, if enough gas forms and the LiPo bursts, it will commonly vent with flames. If a LiPo is discharged below its stated C-rating, there should not usually be a safety issue (unless, as happens occasionally, LiPo manufacturers lie about the C-rating of their batteries). 

    That is why I am supporting smart battery in terms of problem detection.  Recently I went to a drone exhibition and got to know this samrt battery by MMC UAV. The battery claims to free yourself from safety precautions by adopting such functions like over-charge-and-discharge protection, voltage balance, over-current-and-voltage protection, self-discharge protection when inactive for long time, short-circuit protection and cell damage detection,etc.

    MY QUESTION is whether this kind of so-called "SMART BATTERY" really that safe enough and still powers drones as the usual ones?

  4. It looks quite portable and said to be water-and-dust-proof. Has anyone tried this one yet?

  5. I am considering buying a new GCS,  so I finally got to come to these two GCSs. I think I can get some advice from here to choose the final one.

    The first one looks very ruggedized with stabilized tray. The second one looks so portable with chic appearance and it is from a brand I know not so well. Their GCS look so different from traditional ones but it takes risk trying too edgy products, right ?  Tell me what you think, thanks!
