It receives GPS and GLONASS signals at the same time, which supports more consistent positioning than a single-constellation receiver. The refresh rate reaches up to 10Hz, so speed and position updates are frequent enough for detailed tracking. It records a UTC timestamp for each tracking point and stores data in the built-in 1M flash memory, giving up to 2 hours of recording time. The built-in 200 mAh LiPo rechargeable battery provides up to 150 minutes of working time. You can switch between metric and imperial systems, and the GNSS LOGGER software handles device management and data recording on Bing Maps. The firmware can be upgraded when new versions are available. The device measures 65.7 x 39.6 x 20.8mm and comes in black.\u003c\/p\u003e\u003ch2\u003eFeatures and Construction\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Black GNSS speedometer with GPS and GLONASS, 10Hz refresh rate, 65.7 x 39.6 x 20.8mm, built-in 1M flash and 200 mAh battery\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/4923\/2025-10-24\/original-image\/3241059111939.webp\"\u003e\u003c\/div\u003e\u003cp\u003eThe core hardware centres on simultaneous GPS and GLONASS reception, a built-in antenna, and a receiver operating on L1 at 1575.42 MHz.
