| Abstract: | In this paper,satellite ephemeris and GPS carrier-phase observations are used to calculate the velocity/acceleration of vehicle.In the case of field test at UNB,Canada,2007,the comparisons of the velocity/acceleration calculation of vehicle with broadcast ephemeris and with precise ephemeris were conducted,which should support the opinion that broadcast ephemeris and GPS carrierphase observations could meet the needs of real-time navigation of vehicle. |

| Keywords: | GPS satellite ephemeris navigation carrier phase estimating velocity/acceleration |
