VK172 G-mouse USB GPS/GLONASS USB GPS Receiver

VK172 G-mouse USB GPS/GLONASS USB GPS Receiver provides a highly accurate and reliable positioning solution for modern digital platforms. This compact module supports multiple global navigation satellite systems including GPS and GLONASS. Consequently, users experience faster signal acquisition and better tracking in urban canyons or dense foliage. The device utilizes the high-performance U-blox 7 engine to deliver superior sensitivity. Furthermore, its plug-and-play USB interface allows for immediate integration with Windows, Linux, and Android systems without complex wiring. Moreover, the built-in ceramic antenna ensures a strong signal lock while maintaining an incredibly small form factor. Therefore, you can transform any USB-capable device into a precision navigation tool with ease.

Key Features:

• Dual GNSS Support: This receiver tracks both GPS and GLONASS satellites simultaneously. Specifically, this dual-constellation support increases the number of visible satellites for a more stable fix.
• High Sensitivity: The chipset features a tracking sensitivity of −162 dBm. Additionally, it offers a cold start sensitivity of −148 dBm, allowing for positioning in challenging environments.
• Plug and Play: The module uses a standard USB 2.0 interface. As a result, most operating systems recognize it as a standard COM port without requiring manual driver installation.
• Compact Design: Its small, dongle-style footprint makes it ideal for portable applications. Furthermore, the lightweight plastic housing protects the internal components without adding significant bulk.
• Internal Battery: A built-in backup battery retains satellite data. Consequently, the device achieves a “Hot Start” in less than one second.
