*Main Application of the Differential GNSS RTK GPS:
Working Mode Option:
*If you need to do surveying at a palce where is terrain open, without too much control in radio use:
Measuring distance within 3Km: Better to use internal radio working mode;
Measuring distance over 3Km: Better to use external radio working mode.
*If you need to do surveying at a place where the radio use is in strick control,but the network coverage is very good:
If have CORS Site at local,you could choose network RTK working mode;
If don't have CORS Site at local, you could building a simple server.
*If you need to do surveying at a place where radio use is in strick contol,and the network coverage also not fine:
Under this condition,you could choose to use Stop & Go Surveying mode.
