摘　　要：针对动态条件下用户较难验证其接收机载波相位相对定位精度的问题,提出了一种载波相位动态相对定位精度验证方法,即用两个移动站之间的解算基线长度与真实基线长度的差值来间接反映载波相位动态相对定位的精度。仿真结果表明该验证方法有效可行且有效性在94%以上,静态实验结果进一步表明了该方法的有效性,跑车实验验证了载波相位动态相对定位精度为厘米级。To solve the problem that reciver users are difficult to verify the accuracy of relative positioning using carrier phase under the dynamic condition, an authentication method of dynamic relative positioning using car- rier phase is presented, which uses the difference between the calculated baseline length and the true baseline length of two rovers to reflect the accuracy of dynamic relative positioning using carrier phase indirectly. The simulation results show that this method is effective and feasible, and the effectiveness is more than 94%. The static experimental results show further that this method is effective. The dynamic experimental results verify that the accuracy of dynamic relative positioning using carrier phase is centimeter level.
