Overview

About the UA301 BDS-3

The UA301 BDS-3 smart antenna is equipped with the Lyra II baseband chip and Aquila RF chip, supporting full-constellation, full-frequency signal reception and processing across BeiDou, GPS, GLONASS, Galileo, and more. It supports L-Band signal reception and satellite-based augmentation system (SBAS/PPP) positioning services. With built-in Wi-Fi and Bluetooth, the UA301 enables remote WebUI configuration and upgrades for enhanced ease of use. It also features onboard data storage to collect raw observation data in real time, making it well-suited for PPK and other operational scenarios.

Specifications

The UA301 BDS-3 Smart Antenna is powered by the Tianqin II baseband chip and Tianying RF chip, supporting all-constellation, all-frequency signal tracking and processing across BeiDou, GPS, GLONASS, and Galileo, as well as L-band signal reception and satellite-based augmentation positioning services. With built-in Wi-Fi and Bluetooth, the UA301 enables remote WebUI configuration and firmware upgrades for enhanced ease of use. It also features onboard data storage for real-time raw data logging, making it ideal for PPK and post-processing applications.

Featuring superior antenna gain, a stable phase center, and an optimized axial ratio, the UA301 can deliver centimeter-level positioning accuracy via RTK differential positioning when pairing two UA301 units through datalink devices (such as UHF radios or cellular networks). It is widely applicable to agricultural machinery assisted steering, construction vehicles, marine vessels, and surveying, providing high-precision position, attitude, velocity, and timing data.

Features

● All-constellation and all-frequency tracking, supporting BDS-3 and China Precision augmentation service; ● Compact design with built-in Wi-Fi and Bluetooth for easy WebUI remote configuration and upgrades; ● 8 GB internal storage supporting real-time raw data logging; ● Qualified through rigorous environmental testing; ● Supports multiple operating modes, suitable for agricultural machinery assisted steering, construction vehicles, marine positioning, UAV surveying and mapping, and more.
