Tersus Oscar Ultimate

Engineered for challenging environments

Tersus Oscar GNSS Receiver Ultimate

The Ultimate is the top tier of the Oscar series of GNSS Receivers. Its high-performance, multi-constellation and multi-frequency GNSS board provides high accuracy and a stable connection wherever you are. It features an LCD screen and a calibration-free tilt compensation IMU.

Two Large, Detachable batteries

The Oscar comes with 2 swappable, large capacity batteries with power displays. They provide up to 16 hours of battery life and are easily removed.

Internal High Performance GNSS Board

The internal high-performance, multi-constellation and multi-frequency GNSS board supports 576 channels which can track more than 50 satellites.

Rapid Position Fixing

Integer ambiguities fix rapidly once a satellite connection has been acquired and corrections are received. Fixed solutions can be obtained in 3-5 seconds in an open area, and in 10-30 seconds in areas with tree cover or near tall buildings using the high speed antenna.

Multipath Mitigation

Advanced GNSS high-precision baseband IC and RTK algorithms enable the Oscar to not only track more satellites, but also to effectively filter out signal with serious multipath error and low signal-to-noise ratios. In doing so, the Oscar always delivers high-precision results even in urban areas and areas with dense tree cover
