Compatibility Analysis for Starting Data of GPS Network
Wenhui Chen · Geomatics & Spatial Information Technology · 2009
With the rapid development of GPS,it's used in more and more control networks.If there's gross error in the starting point data,or the relative precision between some control points is lower,the precision will drop suddenly after adjustment with restricted condition.Then we can't achieve the anticipated precision.Therefore,we should make the analysis of the starting point's compatibility and process it,so the anticipated order request could be achieved.Based on the GPS network in the Liaoning Technical University,several methods of compatibility analysis were used.A beneficial conclusion is obtained.
