1. Introduction
This chapter includes overview, receiver features, and devices in the package.
1.1 Overview
The Surveying 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 big interactive screen on Ultimate and Advanced
versions. With an internal high-performance multi-constellation and multi-
frequency GNSS board, the Surveying 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 RTK mode. The built-in UHF radio
module supports long distance communication. The rugged housing protects
