System Description
NavCom SF-2040 GPS
Sensors
The LAND-PAK includes
the NavCom SF-2040
Sensor for both the base
station and rover. The SF-2040 is 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 autonomous 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 SF-2040 has a built-in L-Band demodulator for
reception of NavCom’s StarFire™ Network correction
service. The sensor simultaneously accepts
additional DGPS corrections (WAAS/EGNOS)
assuring seamless position output.
