You will find 4 LEDs on the AscTec AutoPilot, which show status information.
- LED 1 (red): Is constantly on as long as the sensors are being initialized.
- LED 2 (green): Low level processor (LLP) status. This LED is blinking rapidly in normal operation. It indicates, that the flight control software on the LLP is running.
- LED 3 (green):: GPS hardware status. If the GPS module is correctly connected and running, it is blinking at 2.5 Hz.
- LED 4 (red): GPS lock status. If it is blinking, there is no valid GPS lock.
AscTec Firefly LED-Fin
The LED-fin on the back of the Firefly displays the status of the UAV.
- During initialization the LED is constantly red.
- After initialization, the fin turns constantly orange as long as there is no valid GPS lock.
- When there is a valid GPS lock, the LED turns green. If somehow the GPS lock is lost, the LED turns orange again.
- Battery indicator: When the battery voltage drops below 11.0V the LED starts changing its color to red. The more the voltage drops, the more the LED changes to red. Below 10.5V the LED additionally starts blinking to indicate that the battery is empty.
Warnings (similar to acoustic warnings):
- Gyro calibration error: the LED blinks red, 2 times every 2 seconds.
- Accelerometer calibration error: the LED blinks red, 3 times every 2 seconds.
- Compass magnetic field strength warning: the LED blinks blue, 3 times every 2 seconds.
- Compass magnetic inclination warning: the LED blinks blue, 4 times every 2 seconds.
- Compass error: the LED blinks blue, 5 times every 2 seconds.
All compass warnings/errors are displayed only three times!
