Benefits of a Reference Station Network
* Eliminate the need for local base stations
* Only GPS rover receivers are needed
* Less initial GPS expense
* No surveyor required to “watch” the base station
* Consistent known datum and coordinate system.
* Avoids common errors on temporary base stations:
Operator sets up on wrong station
Wrong coordinates for base are entered into data recorder
Wrong height of antenna measurement
Wrong antenna type picked during processing
Antenna not plumb over point
Subject to tripod movement or disturbance (wind, bumped, etc.)
Subject to interference with GPS signal (trucks passing, etc.)
* Distance dependent errors modeled better
* Better accuracy of solution
* Longer distance RTK range possible - 60 Km spacing of base stations
RTK Networks are becoming increasingly popular for many reasons, but in today's market
probably the most beneficial are the cost and the ability to survey on the fly with one man.
Topcon offers several solutions for Network RTK surveying. There are options for satellite
tracking (GPS or GPS+Glonass) cell modem (CDMA or GSM) access as well as memory and
tracking options. Combine this state-of-the-art hardware with TopSurv controller software and
you have a full network RTK survey solution.
