!!! The app works only in combination with a Piciorgros TTS-2000 device !!! The app uses the TETRA Site Survey device to manually measure TETRA networks in areas without GPS coverage. This enables the user to create coverage maps of indoor locations. The locations are referenced with internal x/y coordinates with could be mapped to other coordinate systems in a post-processing of the results. A graphical representation of the area (map) can be imported via the internal photo library or with the build in camera of the iPad. Continued use of GPS running in the background can dramatically decrease battery life."
