Function Documentation

void stateCalcPositionLla_i ( void  )

Calculate LLA (int) from any other available representation.

Note that since LLA in float has bad precision this is the last choice. So we mostly first convert to ECEF and then use lla_of_ecef_i which provides higher precision but is currently using the double function internally.
