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 flexibili ty 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.

Oscar GNSS Receiver has three versions: Ultimate, Advanced and Basic (from left to right), provides selectivity for the requirement of different users

Calibration-free Tilt Compensation

Oscar GNSS Receiver is the State-of-the-Art GNSS Receiver developped and built from scratch by Tersus GNSS. With advanced features such as calibration-free tilt compensation and a high-performance multi-constellation and multi-frequency GNSS board, Oscar offers supreme accuracy and stable signal detection even in demanding environments such as urban canyons and under canopy.

Let’s Get Right to the Point

Oscar comes with 2 swappable, large capacity batteries with power displays. Works up to 16 hours (4G/3G/2G network or base-rover radio modes).

Smart Battery

With up to 16GB of memory on board, Oscar supports 300+ days of storage (e.g., at a 15sec sapling rate in TRS format). Standard RINEX also supported.

Smart Battery

Oscar supports UHF, 4G, Wi-Fi, and NFC connectivity. The built-in UHF 2W radio modem enables Oscar to receive and transmit correction data at typical ranges of 5-10km.

Smart Battery

Fully compatible with mainstream formats for correction data. Supports file import and export in various formats.

Smart Battery

IP68 rated dust and water proof. Resistance of 2m pole drop onto concrete. Meets the United States Military Standard of MIL-STD-810G & FIG 514.6C-1.

Smart Battery

Free use of the Tersus Caster Service, a cloud service to transmit and receive corrections over cellular connections, for Oscar bases and rovers. You can support multiple rovers from a single base.

Smart Battery

Full Satellite Tracking

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

Fix in seconds

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.

Compact design

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.
