Chapter 1 Introduction
The NCT-2030M GPS sensor delivers unmatched
accuracy to the precise positioning community who
need a cost-effective, high performance
GPS sensor
with internal data logging capability.
System Overview
„ GPS Sensor
The NCT-2030M sensor consists of a 24-channel dual
frequency precision GPS sensor with two additional
channels for receiving Satellite Based Augmentation
System (SBAS WAAS/EGNOS) 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 115kbps serial ports with less
than 20msec latency. NavCom's NCT-2030M model
sensor delivers unmatched positioning accuracy to
system integrators in need of a cost-effective, high
performance differential
GPS sensor.
The NCT-2030M is packaged for mobility. It can be
used for
Geographic Information System (GIS) , aerial
and hydrographic surveying, and post-processed dual-
frequency surveys. The sensor can be carried in a
backpack with the antenna pole-mounted from the
backpack, or on a survey pole with a single cable
connection. Optionally the NCT-2030M can be
configured to accept
RTK DGPS corrections via an
external source for centimeter level survey accuracy. It is
also possible to utilize NavCom’s StarFire™ network to
obtain real-time accuracies of about 10 centimeters
through a factory upgrade. No external data-logging
