| 摘 要： | 讨论了利用多普勒观测值进行单点测速的观测方程，分析了其误差来源和各误差源对测速精度的影响。用自编软件计算了静态和动态条件下GPS测速的精度，其中动态测速的参考速度采用GrafNav Version7．00软件计算得到，比较结果表明在静态和动态条件下测速精度都可以达到cm／s级

| Abstract: | The Equation of single--point velocity determination with Doppler shift is discussed, the error sources and the effect on velocity determination of error sources are analyzed. The static and kinematic data was processed with software made by the author himself, while the kinematic velocity which was reference velocity was calculated by using GrafNav Version 7.00 software. Compared with both results, it indicates the accuracy of GPS velocity determination reaches cm/s level under static or kinematic condition. |
