IMU Based Tilt Compensation
Empowered by a high precision inertial measurement unit (IMU) on Ultimate version, Oscar GNSS receiver from Tersus is a new generation of tilt survey GNSS receiver. This kind of calibration-free tilt compensation is immune to magnetic disturbances. Oscar gives a surveyor unprecedented flexibility and efficiency – holding the survey pole upright is no longer necessary. With an internal high-performance multi-constellation and multi-frequency GNSS board, the Oscar GNSS Receiver can provide high accuracy and stable signal detection.
Robust Design
The built-in high-performance antenna can speed up the time to first fix (TTFF) and improve anti-jamming performance. With a Nano-SIM card inserted in Oscar, it can access Internet, transmit and receive correction data through 4G/WiFi network. The built-in UHF radio module supports long distance communication. The built-in large capacity battery is detachable and can display power level. Two batteries support up to 16 hours of fieldwork in 4G/3G/2G network and Rover radio mode. Oscar can be easily configured with 1.54 inch interactive screen on Ultimate and Advanced versions. The rugged housing protects the equipment from harsh environments.
