Exceptional tracking performance

The GUS GNSS receiver provides superior tracking of L1 and L5 geostationary satellite signals, as well as L1/L2 GPS signal tracking, which aids in precise system timing. NovAtel's Narrow Correlator® technology is included to enhance the reception of satellite data for highly accurate range measurements. In addition, our advanced algorithms increase reliability by detecting and eliminating cross-correlation.

Independent receiver sections

For flexible operation and configuration, the GUS Receiver features three independent receiver sections, each with its own dedicated antenna inputs. Each receiver section includes a primary Euro-3 card for L1/L2 GPS tracking and a secondary Euro-L5 card, which provides L5 GEO signal tracking. Each section is configured independently through standard RS-232 serial ports. A simple but comprehensive command interface provides tight control of each receiver section.
