H GPS Total Station 4800
H.1 Introduction
The GPS Total Station 4800 system is a fully integrated GPS receiver,
GPS antenna, radio modem, and radio antenna. The 4800 receiver is a
low-latency, fast-update GPS engine designed to provide
centimeter-level positioning for Real-Time Kinematic (RTK) surveys.
It also features on-the-fly initialization for RTK mapping operations
and provides differentially corrected C/A code positions accurate to
better than one meter on a second-by-second basis.

The 4800 unit tracks GPS satellites on both the L1 and L2 frequencies
to provide precise position data for land survey and mapping
applications. The 4800 unit records GPS data and makes all raw and
computed data available through bi-directional RS-232 ports.
