/* |
|
This is a 'mock' implementation of an INS that does nothing and gives a level HUD, but does it successfully. |
|
Its useful for boards that don't have any form of IMU accel/gyro etc connected just yet, but where u want to boot-up "successfully" anyway, |
|
such as the ESP32, to allow wifi connectivity to startup, and alow mavlink to start streaming anyway. |
|
Its a rip-off of _SITL with all the sitl stuff removed or replaced with constants. |
