We are not building “just another RTK system”

No, we have already engineered and built superior RTK systems! We are confident that Oscar can match—or better than—any RTK system out there.

No, we are not just another manufacturer that simply buys OEM GNSS boards from the same manufacturers as everyone else. Tersus develops our own boards and solutions from scratch, following our core philosophy of “build better, or don’t build at all.”

No, we do not charge exorbitant prices, but are not “going for cheap”. You deserve quality products, and we invest in quality R&D accordingly. We will never incorporate cut-rate GNSS components that were designed for non-surveying applications.

No, we do not sell you a system and walk away. We provide rapid support and service, upgrades, and ongoing enhancements. Our engineering professionals work closely with our support team—and you!

No, you are no longer stuck with limited choices; we’re here to make sure of that.

Fixed in Seconds

Integer ambiguities fix rapidly once satellites are acquired and corrections are received. Fixed solutions can be obtained in 3-5s in open sky, and in 10-30s under canopy or near buildings.

Reliable RTK Performance

According to a large number of test cases and results, Oscar can achieve a RMS of about 2cm in various obstructed environments, which is fully competent for various measurement scenarios.

Full Satellite Tracking

Our self-developed GNSS board, with 1792 channels, supports full, multi-constellation tracking.

Multipath Mitigation

Advanced GNSS high-precision baseband IC and RTK algorithms enable Oscar not only to track more satellites, but also to effectively filter out signals with serious multipath error and low signal-to-noise ratios. Oscar always delivers high-precision results even in urban canyons and areas of dense tree canopy, where many other receivers struggle.

The ruggedized Oscar receiver comes with a 4cm (1.54″) interactive screen (Ultimate and Advanced versions)
