Compensation Algorithm of MEMS Heading Sensor on Small UAV
Linfeng Sun, Wei Wang · 2018
According to installation position of heading sensor on UAV, introducing two kinds of heading compensation algorithm. One is improved Honeywell compensation algorithm when heading sensor installed level, the other is improved ellipsoid fitting compensation algorithm when heading sensor didn't install level. According to these two compensation algorithms, this article progressed ground static compensation experiment and flight experiment. According to the output data of heading sensor which compared with high precision inertial guidance data, validated these two different compensation algorithms for different installation position of heading sensor can also realize the high accuracy heading compensations.
