Basic methods of GNSS/GPS setup or measurement


As we know a typical GPS setup needs a base and rover. The Base is setup in the known control point and the rover used for the surveys. Leica GS 15 GPS is taken as example in this post. It can be set up in 3 different methods for the GPS Surveying. They are

  1. Setting up with internal antenna
  2. Setting up with external Radio or antenna
  3. Setting up with GSM modem

It will be described briefly how above mentioned system works.

1.Setting up with internal antenna

In this method the small “L” shaped antenna is fixed in the base and rover. The following photos shows typical internal antenna. The range of coverage  is around 2 km. This method is simple and fast but less coverage. Read More
