VK-172 USB GPS/GLONASS Receiver Module – External GNSS Antenna with Plug-and-Play USB Interface

Description

Description

The VK-172 USB GPS/GLONASS Receiver Module is a compact, high-performance GNSS dongle that brings accurate positioning and timing capabilities to any device with a USB port. Designed as a “G-Mouse” form factor smart antenna, this receiver integrates a powerful U-blox engine (G-7020 chipset) with a built-in active patch antenna, all housed in a lightweight, durable ABS enclosure.

Unlike standard GPS modules that require soldering or UART connections, the VK-172 connects directly via USB and is recognized as a virtual COM port, providing a simple NMEA-0183 data stream to your operating system. It supports both the American GPS and Russian GLONASS satellite constellations, offering enhanced accuracy and faster Time-To-First-Fix (TTFF) compared to GPS-only receivers.

With 56 tracking channels and support for DGPS (WAAS, EGNOS, MSAS), the VK-172 achieves positional accuracy of approximately 2.5 to 3.5 meters in open sky conditions. Its high tracking sensitivity of -162 dBm ensures reliable performance even in challenging signal environments.

The VK-172 is widely compatible with operating systems including Windows (XP through 11), Linux (driver-free on most distributions), Android, and Raspberry Pi systems. It is an ideal solution for vehicle navigation, aviation tracking, Raspberry Pi projects, time synchronization, and any application requiring USB-based GPS/GLONASS data.
