A Widelane Integer Resolution Technique for Relative Navigation between Spacecraft

Patrick W. Binning

Abstract:	It is desired to precisely locate two satellites with respect to each other using the Global Positioning System. This is simulated using a Nort hem Telecom STR2760 GPS signal simulator and an Allen Osborne TurboRogue receiver. The observations are retrieved from the TurboRogue while the truth model is taken from the Nortel. The observations are then processed through the Naval Research Laboratory’s orbit deter-mination program OCEAN (Soyka et al., 1997, 1998). The relative states are estimated using an extended Kahnan Filter. The observation update employs the single difference widelane combination of the dual frequency carrier. Inherent in this observation are unknown integers which are determined using a com-bination of techniques common to terrestrial locating. The results are 1 a, 3-d, relative position errors on the order of 1 to 3 cm.
