Abstract
Accuracy of a positioning device may be determined without requiring the device to be at any specific location, such as a test location. Instead of comparing the reported location and directional data to a known location and directional data, the present technology may use multiple discrete location and directional reports for comparison with the reported data at multiple locations. The multiple comparisons are used to assess the relative accuracy of the positional telematics system. The reported location may be a GPS location or from another positioning system.
