Following an earlier recognition of degraded monthly geopotential recovery from GRACE (Gravity Recovery And Climate Experiment) due to prolonged passage through a short repeat (low order resonant) orbit, we extend these insights also to CHAMP (CHAllenging Minisatellite Payload) and GOCE (Gravity field and steady state Ocean Circulation Explorer). We show wide track-density variations over time for...
. Due to the Global Positioning System (GPS), points on and above the Earth’s surface are readily given by means of a triplet of the Gauss surface normal coordinates L,B and H called ellipsoidal longitude, ellipsoidal latitude, and ellipsoidal height, respectively. For geodetic applications, these curvilinear coordinates refer to the international reference ellipsoid GRS80, which is an equipotential...
