As well as VBOX 3i, we have also launched a 20Hz RTK and Glonass upgrade, increasing the positional accuracy of VBOX 3i to 2cm when used with an RTK enabled base station. The combination of 100Hz GPS, 20Hz base station RTK signals, and 20Hz Russian Glonass signals, means that this is our most accurate system to date. However, 50Hz and 100Hz RTK/Glonass systems are in development and will be announced shortly!
