Developed entirely in-house, our state-of-the-art four-channel GNSS Software-Defined Radio (SDR) device is designed to acquire and process GNSS signals with exceptional efficiency and precision. This versatile hardware forms the backbone of a wide array of advanced applications. It plays a critical role in remote sensing, enabling enhanced environmental monitoring and geospatial data collection. In anti-jamming scenarios, it ensures signal integrity and resilience, even in challenging or hostile environments. Additionally, the device supports array antenna beamforming, significantly improving signal accuracy while minimizing interference. This powerful combination of capabilities makes our GNSS SDR an essential tool for next-generation positioning and navigation solutions.
