UvAGPS Data Model

For different versions of the UvAGPS firmware different tables are used. For firmware version v0.9.3.6 till v1.0.0.X the tables UVA_ENGINEERING_DATA and UVA_TRACKING_DATA are used. But in the new firmware versions 1.0.1.4 till 1.0.2.4 so much information was added that new tables were introduced. However for the most important tracking tables a view is created so that all similar tracking for all types of firmware can be seen in one view. That is the UVA_TRACKING view.

UVA_TRACKING_DATA

Tracking data from UvA GPS tags for older firmware
