Effect of erroneous observations in GPS-based LEO satellite orbit determination
Performance of an EKF-based Orbit Determination (OD) algorithm using Global Positioning
System (GPS) measurements is examined under erroneous observation conditions. A
generalized formulation of a dynamic orbit model is designed to predict the satellite states in
an Earth-Centered Earth-Fixed (ECEF) frame. A suitable orbit interpolation method is then
chosen for interpolating the GPS satellite position at the measurement time tag before
finding the geometric range between the GPS and the LEO satellites. Thereafter, the …
