Discussion on the deformation monitoring of short baseline based on the single-frequency GPS receiver

We can make use of single-frequency receiver and dual-frequency receiver to monitor monitoring points on Shunxi landslide,then process and analyse the data combined with the relative baseline from datum point which is measured by total station to monitoring point.Finally,we can get the conclusion that better precision will be achieved when we use single-frequency receiver on control network of short baseline,at the same time,not only saving the engineering cost,but also making it easy to operate when conducting periodic re-testing.
