Surveying Statistics - Part 1: I DON'T NEED NO STINKIN' STATISTICS

摘要

When performing a GNSS survey, you are gathering multiple observations for the determination of a single baseline. Typically you will form loops with these baselines to check their closures and to adjustment them. In this entire process you are performing least squares adjust. You may not realize this at the time since your software is doing all the computations. However, at the end of each process, you can stop and look at a statistical output from the adjustment and analyze the results of the adjustment. This occurs whether you are using the manufacturer's software or the NGS's OPUS solutions.
