1. Introduction
This chapter includes overview, receiver features, and devices in the package.
1.1 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 harsh environments.
