Oscar GNSS Receiver
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.
No hassle in getting fixed position even on the harshest environment, even under 13000 megawatts of the electric tower, yet able to relocate control points.
I am using Tersus for geophysical and geological investigations. I find it very simple to use, complete and reliable.
The David system performed admirably, and that was just the entry-level system. I am expecting the future test drive of the Oscar to go as well and likely better with the additional constellation.
