Abstract
The gravitational anomaly has a strong influence on navigation errors especially for entire near-space cruise. In this study, an online compensation method of gravity anomaly has been developed from gravitation characteristics at different altitudes and the typical flight profiles of near-space vehicles. This technology is based on combining standard gravity interpolation at low altitudes with spherical harmonic coefficient calculation at high altitudes to meet the gravitational computation requirements within constraints of the onboard computer system. It can significantly decrease demands for gravity anomaly and increase autonomous navigation accuracy and disturbance rejection performance.
