How accurate is VBOX?
High end VBOX systems used for automotive testing (i.e. Advanced Driver Assistance Systems) can provide up to 2 cm positional accuracy. This level of accuracy is usually not required for mining users – where common VBOX products used on-site are shown below.

* Absolute Positioning and Height accuracy is measured as 95 % Circle of Error Probable (CEP). This means 95 % of the time the position readings will fall within a circle of the stated radius.
** VB2SX Brake Stop Accuracy refers to stopping distance as tested on a standard passenger vehicle, and may vary on a haul truck depending on the fitment and movement of the GPS antenna.
*** VB2SX Absolute Positioning Accuracy:
- With SBAS DGPS: <1 m in Europe, <1.8 m in USA and Asia
- With RTCM DGPS: 40 cm
- With local upgrade: 20 cm
**** VB2SX Height Accuracy:
- With SBAS DGPS: ±2 m
