What is GPS latency and does it affect accuracy?

Table of contents
No headers

GPS latency is the time between the measurement of velocity, and when the VBOX reports this velocity.

This is only an important factor when using the VBOX velocity output compared with any external signals such as a brake trigger.

If you are using the VBOX with the supplied VBOX Tools software, or the multifunction display, then the latency is taken into account and does not affect the accuracy in any way.

If you are taking the CAN output of a VBOX or the raw data from a logged file, then you will need to be aware of the latency, and take this into account.
