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
