| Abstract: | GPS kinematic carrier phase measurements can be used to determine seven dimensional state and three attitude parameters of a motional carrier such as an aircraft and low earth orbit spacecraft,on which an antenna is installed to receive GPS signals.It is known from airborne GPS test results for photogrammetry in China since 1994 that GPS carrier phase measurements in a motional environment have acquired external accuracies of ±7.9cm for two dimensional positions and ±18.1 cm for point heights. |

| Keywords: | airborne GPS receiver GPS kinematic carrier phase measurement multireference ground station |
