Position Quality Configuration

Feature description

Sometimes shared vehicles are parked underground or in an area with high rise buildings. In both conditions GPS performance of the cloudboxx can be bad and the location of the vehicle in the app can be off by several hunderds of meters because of a bad gps fix or none at all. Although the car might be parked in it's proper home zone, the app reports it's not and the user cannot end its reservation. To fix these problems the position of the car can be overwritten by a predefined position under certain circumstances. The configuration of this can be done in Control Center.

Configuration parameters

The configuration takes 4 parameters.

1. max meter limit: this is the threshold of how many meters the car should have driven since last receiving a correct GPS position. If this limit is reached (together with the HDOP limit) the position is overwritten. Recommanded value to start with: 500
2. HDOP: HDOP stands for horizontal dilution of precision. HDOP is a measure of the confidence level of the last GPS fix. The lower this number the more confident and the better the last GPS position was. If a GPS fix has a higher HDOP than this parameter (and the max meter limit is reached) the position is overwritten. Recommanded value: 1
3. latitude: latitude of the overwrite position
4. longitude: longitude of the overwrite position

The overwrite position is defined by the coordinates in latitude and longitude. You can manually enter these value are select a position on the map

Configuration in Control Center

The position quality configuration is set on the level of a physical vehicle. To add a configuration for a certain vehicle go in Control Center to "cars", select the car and open the "position quality configuration tab". Here you can add a configuration, remove it and edit the parameters.
