2050 User Guide
Chapter 1 Introduction
The 2050 GPS sensor delivers unmatched accuracy to the precise positioning community who
need a cost-effective, high performance GPS sensor. These unique receivers use the StarFire

Network, NavCom’s worldwide Differential GPS system, for instant decimeter level position
accuracy, virtually anywhere in the world, anytime.
System Overview
GPS Sensor
The 2050 sensor consists of a 10- channel dual frequency precision GPS sensor with two
additional channels for receiving Satellite Based Augmentation System (SBAS) signals and
an L-Band demodulator for reception of C-Nav StarFire

Network correction service, for
decimeter-level position accuracy, anywhere in the world, anytime. 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. The 2050 model sensors deliver
unmatched positioning accuracy to system integrators needing a cost-effective, high
performance differential
GPS sensor.
The 2050 has a built-in L-Band demodulator for reception of C-Nav StarFire

Network
correction service giving an immediate solution for the user utilizing the global Real-Time
Gypsy (RTG) and regional Wide area Correction Transform (WCT) solutions. Additionally,
the unit can accept corrections for
DGPS, WAAS/EGNOS, assuring seamless position
output.
The 2050G is packaged for mobility. It can be used for Geographical Information System
(GIS) , aerial and hydrographic surveying, and post-processed dual-frequency surveys. The
GPS sensor can be carried in a backpack with the antenna either pole-mounted from the
backpack or on a survey pole with a single cable connection.
The 2050M is ideal for vehicle mounting to suit a wide variety of machine guidance and
control applications in agriculture, mining, aerial, and hydrographic surveying. It is equipped
with additional features allowing interconnectivity with a wide variety of antennas, vehicle
data busses and other instrumentation to suit specific applications and configurations. The
2050M also has a 1
PPS output port and a combined Event/CAN Bus interface port.
Both 2050 models 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 20ms latency. The horizontal accuracy of 1 cm or better and the vertical accuracy
of 2 cm or better are maintained as each output is independently calculated based on an
actual
GPS position measurement, as opposed to an extrapolation between 1Hz
measurements.
