An ever increasing number of low Earth orbiting (LEO)
satellites is, or will be, equipped with retro-reflectors for
Satellite Laser Ranging (SLR) and on-board receivers
to collect observations from Global Navigation Satellite
Systems (GNSS) such as the Global Positioning Sys-
tem (GPS) and the Russian GLONASS and the European
Galileo systems in the future. At the Astronomical Insti-
tute of the University of Bern (AIUB) LEO precise or-
bit determination (POD) using either GPS or SLR data is
performed for a wide range of applications for satellites at
different altitudes. For this purpose the classical numeri-
cal integration techniques, as also used for dynamic orbit
determination of satellites at high altitudes, are extended
by pseudo-stochastic orbit modeling techniques to effi-
ciently cope with potential force model deficiencies for
satellites at low altitudes. Accuracies of better than 2 cm
may be achieved by pseudo-stochastic orbit modeling for
satellites at very low altitudes such as for the GPS-based
POD of the Gravity field and steady-state Ocean Circula-
tion Explorer (GOCE).
