摘要
在GPS控制测量中,环检验是个不可或缺的步骤,其目的在于及时发现粗差,控制整网的精度。本文通过设计一个环检验程序,从算法角度讨论了手工检验和自动检验的具体实现,并详细介绍了针对复杂网形控制网构环算法的优化,保证了程序的可靠性和稳健性。
The baseline loop checking is an indispensable step in GPS control network and the goal is finding out gross error to control the accuracy. This article disscussed the realizations of manual loop checking and automated loop checking in the way of arithmetic by design a checking program, and introduced an optimized arithmetic aiming at the complex network form, improved the reliability and steadiness of the program.
