GNSS Receiver



  • 72-Channel High Performance u-blox M8 engine.
  • –167 dBm sensitivity for reliable positioning in challenging Conditions.
  • Extremely fast TTFF (Time To First Fix) at low signal level.


WGM-30X is a highly sensitive which is a built-in antenna. You can use the GNSS Receiver in automotive navigation, security tracking purpose, map making and fleet management. Providing reliable positioning in difficult environments, meet even the most stringent requirements in versatile industrial and consumer applications, such as UAVs, vehicles (car, truck, bus etc.) and asset tracking. The optional connectors of USB and PS / 2 enable the connection with a laptop, car PC and other electronic devices. It’s compatible with Microsoft Windows 10, 8.1, 8, as well as 7, Vista.
