Empowered by a high-precision inertial measurement unit (IMU) on the Ultimate version, the Oscar from Tersus GNSS is a new generation of tilt survey receiver. Its calibration-free tilt compensation is immune to magnetic disturbances ­— holding the survey pole upright is no longer necessary. Powered by Tersus ExtremeRTK GNSS technology, Oscar can provide high accuracy and stable signal detection.

The built-in high-performance antenna can speed the time to first fix (TTFF) and improves anti-jamming performance. With a Nano-SIM card, Oscar can access the internet and transmit and receive correction data through 4G/Wi-Fi. The built-in UHF radio module supports long-distance communication. A detachable smart battery can display power levels. Two batteries support up to 16 hours of fieldwork in 4G/3G/2G-network and rover-radio mode. Oscar can be configured through a 1.54-inch interactive screen on the Ultimate and Advanced versions. The IP67-rated rugged housing protects it from harsh environments.

The Tersus Caster Service (TCS) helps surveyors set up a GNSS base station quickly to broadcast a correction stream via mobile networks. Natively supported by FieldGenius and Nuwa App, Oscar can be configured to different work modes to suit various daily jobs.

Satellite Tracking. Oscar supports multi-constellation and multi-frequency satellite tracking, including GPS, GLONASS, BeiDou, Galileo, SBAS and QZSS.

Accuracy. With enhanced positioning accuracy and constellation tracking, even in harsh environments, Oscar controls deviation within 3cm in surveying and mapping applications.

Quick Fix. Oscar can fix integer ambiguity rapidly after tracking satellites and receiving correction data: 3–5 seconds in the open sky, and 10–30 seconds under canopy or near buildings.
