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
