VBOX Sport 10Hz VBOX Sport units sold after June 2019 will come with an upgraded GPS receiver which is able to receive multiple constellations. The new receiver operates at 10 Hz instead of 20 Hz and tracks the Russian GLONASS range of satellites in addition to GPS.
The advantage of using both satellite constellations is that there are almost twice as many satellites in view, helping to maintain a robust satellite connection and increasing the accuracy of the speed and position signal in challenging GNSS reception areas. Challenging areas include tree lined roads, tall buildings and large structures that can block and reflect GNSS signals.
Due to the way the software calculates acceleration, deceleration and lap timing results, this data is not affected by the drop in sample frequency. For most, if not all, motorsport and automotive applications the difference between 10 Hz and 20 Hz is negligible. In areas with poor GNSS reception you should see an improvement on lap timing results due to better signal quality.
