Chapter 1 Introduction
The RT-3020 GPS sensor delivers unmatched accuracy
to the precise positioning community who need a
cost-effective, high performance
GPS sensor. This
unique receiver can transmit or receive corrections via
an onboard
Spread Spectrum Radio (SSR) .
System Overview
„ GPS Sensor
The RT-3020 sensor consists of a 24-channel dual
frequency precision
GPS receiver with two additional
channels for receiving Satellite Based Augmentation
System (SBAS) signals. The sensor can output
proprietary raw data as fast as 50Hz (optional) and
Position Velocity Time (PVT) data as fast as 25Hz
(optional) through two 115 kbps serial ports. The RTK
software provides fast initialization. Testing shows that
the system resolves ambiguities at start-up or on
reacquisition of satellites typically within two seconds.
The RT-3020 has a built-in Spread Spectrum Radio
providing an immediate solution for the system
integrator and real time surveyor. Utilizing the built in
radio for
RTK measurements, the receivers
communicate using NavCom’s highly efficient
proprietary
RTK format or other RTK formats, such as
RTCM and CMR. Additionally, the receivers
simultaneously accept corrections for DGPS
( WAAS/EGNOS ) assuring seamless position output.
The RT-3020S is packaged for mobility. It can be used
for construction stakeout, boundary surveys, high order
control surveys and topographic surveys in rough
