Onboard orbit determination using GPS observations based on the unscented Kalman filter

An innovative navigation scheme of powered descent phase for Mars pinpoint landing

“…Innovatively, Mars Orbiter (MO) can be also used as navigation sources through radio communication which has a much better real-time performance. Like GPS, the vehicle states will be determined if there exist three or more visible orbiters (Choi et al, 2010;Guo et al, 2010). Nevertheless, the limited number of MO is far away from satisfying navigation requirements, so other navigation sensors should be supplemented.…”

Orbit determination via adaptive Gaussian swarm optimization

“…Besides estimation of the satellite position and velocity, he also considered the thrust force as a disturbance to be estimated using EKF. Choi et al (2010) estimated the position and velocity utilizing UKF and based on GPS C/A code pseudo range. Psiaki and Hinks (2007) has also investigated the problem of estimating the position and velocity vectors of a spacecraft in a lunar orbit based on measurement of star occultation/ rising times behind moon.…”

On-Board Orbit Propagator and Orbit Data Compression for Lunar Explorer using B-spline

“…However, the methods cannot be applied to a deep space probe because the orbital characteristic for the deep space navigation is not periodic. Orbit determination within the satellite itself using GPS measurement data has also been studied [9][10][11][12]. The orbit estimation methods for satellite mounting include a batch filter, a sequential filter, and Kalman filter, etc.…”
