Dual-Frequency RTK GNSS Module WKG035BT0FY01

WKG035BT0FY01 is a dual-frequency RTK GNSS module supporting BDS, GPS, QZSS, SBAS and Galileo. It provides centimeter-level high-precision positioning for UAV, surveying, precision agriculture and robotics.

Product Overview

1. Functional Description

WKG035BT0FY01 is a high-performance 35 × 35 × 13 mm multi-GNSS dual-frequency RTK high-precision positioning module. The module is based on the ATGM332D-F8P multi-frequency, multi-constellation GNSS module independently developed by Allystar, together with high-precision positioning algorithms. It supports multiple satellite navigation systems, including BeiDou-2, BeiDou-3, GPS, QZSS, SBAS, and Galileo, as well as L1 and L5 frequency bands. It can simultaneously receive signals from multiple satellite navigation systems to achieve combined positioning, navigation, and timing.

WKG035BT0FY01 integrates carrier-phase smoothing and multi-frequency ionospheric interference mitigation technologies, enabling centimeter-level positioning accuracy when used with a base station or CORS network. Its multi-constellation and multi-frequency positioning capability improves satellite visibility and ensures high reliability in challenging environments such as urban canyons, wooded areas, and areas under elevated roads or bridges.

The module features a built-in high-speed RTK engine for rapid initialization. Its adaptive anti-interference algorithm can intelligently identify and suppress multipath effects and electromagnetic noise. With a low-power hardware and software architecture, WKG035BT0FY01 achieves a good balance between continuous high-precision positioning performance and power consumption.

With the advantages of high integration, high performance, low power consumption, and cost-effectiveness, WKG035BT0FY01 is suitable for applications including high-precision positioning and navigation, smart logistics, precision agriculture, intelligent driving, and other high-accuracy navigation systems.
