Tersus Oscar Trek

Tilt Compensation with Photogrammetry

Tersus Oscar GNSS Receiver Ultimate

The Oscar Trek GNSS Receiver is the latest high-precision GNSS RTK system, which innovatively brings together visual positioning technology, GNSS, IMU and a camera. It enables the user to carry out high-precision, high-efficiency and multi-point measurements. It also has a calibration-free, tilt compensation function which is immune to magnetic disturbances, meaning that measurements can be taken when the survey pole is at an inclined angle.
The Oscar Trek is easy to configure with a 1.54 inch interactive screen. With its internal multi-constellation and multi-frequency GNSS board, the Oscar Trek GNSS Receiver can provide high accuracy measurements with a stable signal detection.

Two Large, Detachable batteries

The Trek 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

The high-performance antenna can speed up the time to first fix (TTFF) and improve the anti-jamming performance of the receiver. 

Inbuilt Camera

The inbuilt camera enables the user to measure what they see. In conjunction with the GNSS antenna, the camera can take accurately positioned photos which can later be used to build a point cloud.
