Abstract

Three types of formation flight operational schemes are designed. They are combined with the IRI2001 model, to study the effect of ionospheric delay in relative positioning by onboard GPS of space-aircraft. Deep analyses also make for double-differential ionospheric delay of single frequency GPS onboard LEO satellite. Some useful conclusions are drawn for ambiguity solution in carrier phase positioning in such a case that two spacecraft with 1100km high from the Earth and a distance from 150km to 200km. The residuals of double-differential ionospheric delay usually don’t affect the solution of the ambiguity.
