DENEB GBM200
Man-portable RTK receiver with an integrated 865–867 MHz RF modem
The DENEB, DNB-GBM200 is a RF modem integrated multi-frequency, multi-constellation RTK GNSS receiver that delivers meter level position accuracy in standalone and centimeter level position accuracy in Real Time Kinematic (RTK) mode. The rugged design of DNB-GBM200 meets the operational requirements of autonomous vehicles and robotics. It is also suitable for surveying and handheld applications where weight and size matter.
The DENEB DNB-GBM200 is a low powered receiver optimised for hand-held and man-pack operations. As opposed to bulky survey grade receivers, the GBM-200 can be carried in a backpack and powered with an external low SWAP battery to run for tens of hours in the field at a stretch. The GBM200 also features LED indicators for GNSS mode indication, health indication and RF communication.
Key Features
From satellite to system, in real time
Multi-constellation signals and RTK corrections converge at the antenna, are resolved into an RTK-corrected fix inside the receiver, and stream out as NMEA, RTCM and 1PPS data.
GNSS Acquisition
Multi-constellation signal capture across L1/L2/L5 bands
RTK Resolution
Onboard processing resolves carrier-phase ambiguity to 1 cm
Data Output
NMEA 0183, RTCM v3 and 1PPS streamed to the host system
