Comparison of Gps-based Orbit Determination Strategies
نویسندگان
چکیده
Orbit determination strategies for the on-ground trajectory reconstruction of Low Earth Orbit satellites are compared. The analyzed strategies involve different GPS measurement types comprising navigation solution, single or dual-frequency pseudorange, as well as carrier phase measurements. Furthermore, different processing techniques such as kinematic or reduceddynamic processing are addressed. Two sample sets of GPS BlackJack measurements are employed, that were obtained in the framework of the CHAMP mission. It is shown that the resulting position accuracy ranges, depending on the adopted strategy, from 10 m to better than 10 cm.

Multi-Observations Initial Orbit Determination based on Angle-Only Measurements
A new approach with the ability to use the multiple observations based on the least square approach has been proposed for initial orbit determination. This approach considers the Earth’s Oblateness by using the developed Lagrange coefficients. The efficiency of the proposed method has been tested in two scenarios. The first scenario is to use the simulated and the second one is to utilize the r...
متن کاملKinematic and reduced-dynamic precise orbit determination of low earth orbiters
Various methods for kinematic and reduced-dynamic precise orbit determination (POD) of Low Earth Orbiters (LEO) were developed based on zeroand double-differencing of GPS carrier-phase measurements with and without ambiguity resolution. In this paper we present the following approaches in LEO precise orbit determination: – zero-difference kinematic POD, – zero-difference dynamic POD, – double-d...
متن کاملDetermination of GPS Orbits to Submeter Accuracy
Orbits for satellites o f the Global Positioning System (GPS) have been determined with submeter accuracy. Tests used to assess orbit accuracy include orbit comparisons from independent data sets, orbit prediction, ground baseline determination, and formal errors. One satellite tracked for 8 hours each day shows rms errors below I m even when predicted more than 3 days outside of a 1-week data ...

Limiting factors for the precise orbit determination POD of low-earth orbit LEO satellite using dual-frequency GPS are nowadays mainly encountered with the in-flight phase error modeling. The phase error is modeled as a systematic and a random component each depending on the direction of GPS signal reception. The systematic part and standard deviation of random part in phase error model are, re...
متن کاملGps-based Navigation and Orbit Determination for the Amsat Ao-40 Satellite
The AMSAT OSCAR-40 (AO-40) spacecraft occupies a highly elliptical orbit (HEO) to support amateur radio experiments. An interesting aspect of the mission is the attempted use of GPS for navigation and attitude determination in HEO. Previous experiences with GPS tracking in such orbits have demonstrated the ability to acquire GPS signals, but very little data were produced for navigation and orb...
