Position accuracy testing system

摘要

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.

主权项

1. A method for determining accuracy of positional data, comprising:
receiving positional data from a positional device associated with a vehicle, wherein the vehicle is traversing a roadway as the positional device generates the positional data; storing the received positional data in a memory of a computing device; selecting positional data points from the received positional data; comparing the selected positional data points to geo-data points for the roadway over which the vehicle was traversing during generation of the positional data by the positional device associated with the vehicle; determining an accuracy of the positional data points based on the comparison against the geo-data points; and generating a report including the determined accuracy.
