Autonomous satellite state determination by use of two-directional links

Distributed Orbit Determination for Global Navigation Satellite System with Inter-Satellite Link

“…Spatial orientation problem is solved by the combination of the ISL and satellite-toground measurements. The simulation for Galileo system showed that URE is on the level of decimeters [10], which is better than that of GPS. For the distributed navigation algorithms, several techniques including iterative cascade extended Kalman filter (ICEKF), increased measurement covariance EKF (IMCEKF), and Schmidt-Kalman Filter (SKF) are discussed by Schmidt, Park and Ferguson [11][12][13].…”

Research on the Rotational Correction of Distributed Autonomous Orbit Determination in the Satellite Navigation Constellation

“…Remote Sens. 2022, 14,3309 If there is an overall rotation error with a rotation quantity of θ θ α , θ β , θ γ in the constellation for autonomous orbit determination, then according to the criteria for coordinate transformation, the estimated value X of the satellite position state is…”
