Purpose:
The measuring of kinematic and dynamic parameters; the unmanned vehicle control on a given trajectory.
Performance capabilities:
- determination of the unmanned vehicle orientation and navigation parameters;
- the unmanned vehicle control at the given points (at most 255);
- the flight data registration with sampling frequency 50Hz;
- the current information distribution in telemetric channel and its representation at ground computer monitor;
- switching to interactive control mode from standard remote-control station;
- setting of different kinds of control feedback for angle, altitude and flight rate damping and stabilization;
- the feedback coefficients and flying program changing "in flight".
Autopilot structure:
- INS board with micromechanical inertial sensors (accelerometers and gyros), controller for PWM-direction of control-surface actuators, flesh-memory for storage of flight information;
- magnetic yaw sensor board;
- onboard modem for telemeter information transmission;
- ground modem with directional antenna for command-telemetric information transmission;
- GPS receiver (protocol NMEA) with antenna;
- software of ground station for parameters' visualization, autopilot tuning, flight program forming and flight data analysis.
