ExtremeRTK™ Patented Technology
Full Satellite TrackingOur self-developed GNSS board, with 576 channels, supports full, multi-constellation tracking
|
Multipath MitigationAdvanced 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.
|
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. |

Overview
The Oscar GNSS Receiver is a new generation GNSS RTK system. It supports calibration-free tilt compensation function which is immune to magnetic disturbances, leveling pole is not required. Easy configuration with 1.54 inch interactive screen on Ultimate and Advanced versions. With an internal high-performance multi-constellation and multi-frequency GNSS board, the Oscar GNSS Receiver can provide high accuracy and stable signal detection. The high-performance antenna can speed up the time to first fix (TTFF) and improve anti-jamming performance. The built-in large capacity battery is detachable, two batteries support up to 16 hours of field work in 4G/3G/2G network and Rover radio mode. The built-in UHF radio module supports long distance communication. The rugged housing protects the equipment from challenging environments. |
