Introduction
The SF-2040
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 SF-2040 sensor consists of a 24-
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 NavCom’s
StarFire
™ Network correction
service, for instant 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 with less
than 20ms latency. The horizontal accuracy of 10 cm or
better and the vertical accuracy of 15 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. NavCom's SF-2040 model sensors
deliver unmatched positioning accuracy to system
integrators needing a cost-effective, high performance
differential
GPS
sensor.
The SF-2040 has a built-in
L-Band
demodulator for
reception of NavCom’s
