Overview
About the UA204
The UA204 integrated GNSS antenna provides a cost-effective, high-precision positioning solution. Integrated with a built-in GNSS receiver, high-precision antenna, and MEMS sensor, it covers signal reception for BeiDou, GPS, GLONASS, Galileo, and L-Band. Featuring satellite-based augmentation high-precision positioning, it can achieve 25 cm (RMS) positioning accuracy with a single antenna without differential corrections. With excellent antenna gain, phase center stability, and axial ratio performance, datalink equipment (UHF radio, network, etc.) can be used to connect two UA204 antennas for RTK differential positioning to achieve centimeter-level positioning accuracy. It is dedicated to providing high-precision position, attitude, velocity, and timing data for agricultural machinery assisted steering, construction vehicles, vessels, surveying and mapping systems.
Overview
The UA204 GNSS smart antenna provides a cost-effective, high-precision positioning solution. Integrating a built-in GNSS receiver, high-precision antenna, and MEMS sensor, it tracks BeiDou, GPS, GLONASS, Galileo, and L-Band signals. Featuring satellite-based augmentation high-precision positioning capability, it achieves 25 cm (RMS) positioning accuracy on a single antenna without local differential corrections. With excellent antenna gain, phase center stability, and axial ratio performance, two UA204 antennas can also be connected via datalink devices (UHF radio, network, etc.) for RTK differential positioning to achieve centimeter-level accuracy. It is specifically designed to provide high-precision position, attitude, velocity, and timing data for agricultural machinery assisted steering, engineering vehicles, marine vessels, surveying and mapping, and other systems.
