Reference Station Networks
– What are they?
– Where are they?
– Who uses them?
– How do you use them, and what do I need in order to use
them?

What is a GNSS Reference Network?
�Multiple GNSS receivers connected together
via a Common Control Center operating 24/7
� Provides regional solutions on a common Datum
and Coordinate System
� Supports:• DGPS – Sub-meter
• Real Time Kinematic (RTK)

US Network Coverage
Indiana GIS Conference - February 2010
The server continuously takes data from each station
The user dials in to the server and establishes data
communication
DGPS or RTK corrections are sent to the user for real-time accuracy
How Does it work?

Benefits of using Networks
� Real-time Accuracy
� No base setup for RTK surveying
� No WAAS / SBAS corrections
� No External USCG Beacon Receiver
� No or Very Little Post-processing Required
