Ground Control Software (GCS)
We are close in final testing for a totally new custom scratch-made GCS with:
Needless to state here MASSIVE changes have been made to Atto’s telemetry protocol to allow large scale multi-agent support as a realistic and usable feature.
>>>Essentially, the GCS is now a powerful one stop shop for everyting Atto. It communicates everything to Atto wirelessly. This was one of the most sorely lacking items in AttoPilot over the last 2 years/p>
Command Set for Telemetry
Here is a lot of the new magic. Vehicle ID is part of every communication string, plus there is a universal ID to control all vehicles at once with a single command if the situation warrants (abort mission and go to rally coordinates for example). Data protocol is still simple duplex serial 8N1 ASCII (not binary) and protocol will be fully published as has been done in the past. This allows customer custom GCS development for special projects. This also allows industrious users to connect Atto to their 3rd party microcontroller on board the UAV itself and use Atto as a sophisticated stabilization system in order to do things like test/use custom navigation control laws, or dynamic gain scheduling for adaptive control to adjust for vehicle damage in flight by manipulation of any and all 120+ tunable parameters, or triggering the camera or payload based on some rule set other than how AttoPilot typically controls the trigger.
The new command set has 24 commands.
There have been > 2,000 miles of autonomous flight by myself of the V3.0 IMU autopilot. It has proven to be robust and mature. Feedback from a few dozen early customers confirms this. Many new features and commands have been implemented, such as telemetry port based commands to override of roll, pitch and airspeed targets with automatic timeout. Also pitch based airspeed and throttle altitude with user-defined blending mix % with the older method of pitch altitude and throttle airspeed over user-defined altitude ranges.
The newer adaptive navigation methods have proven robust as well. Wind is never a concern for good (customers use the word ‘great’) navigation. Attopilot has a lag-free method to auto-tune navigation gains despite wind and doesn’t at all rely on a wind model to do so. As had been implemented > 1 year ago, Atto does not let the UAV ground speed drop below a minimum value so long as the vehicle has sufficient thrust for the wind conditions. The only concern for the pilot in command when making a go/no-go decision for flight is if the vehicle can maintain at least 15 km/h airspeed above the wind speed. There is absolutely no concern about wind exceeding 50% of the cruise speed, again it is a mere 15 km/h margin as a flat value.
The V2.0 thermopile Atto pilot shares ALL features with the V3.0 IMU autopilot including telemetry commands and auto-tuning navigation. The only thing it lacks relative to the IMU version is inertial yaw rate sensing and thus cannot perform yaw rate dampening in RC or the other flight modes.
