Technique for Optimising GPS Activity Via Identification of Fixed Routes
Mobile devices can track the location of the device at frequent intervals. When a user is on route, following the instructions of their navigation app, the mobile phone location service is constantly active. When the mobile phone detects location changes, it updates the position in the app and makes updates as necessary.
Mobile phones use A-GPS to determine geolocation. A-GPS combines GPS satellites and cell tower data to find a position and improve the precision of the location.
A route can often contain sections where a vehicle has no opportunity to change its course. These will be referred to as “fixed paths” in the rest of the document. An example of a fixed path could be a tunnel with no exits (see [Figure 1]), where the driver can only go forward, or the section of a motorway between an entry and exit point.
When a user enters a fixed path, GPS can be suspended until the user abandons the end of it. This improves the battery drainage caused by using GPS to determine the user’s position in the map by using the accelerometer instead.
To calculate the fixed paths, we will need to determine whether the route is using rail tracks or roads.
a) Rail path. The points where a rail track route course can change is in a fork. b) Roads. Diversion points are roundabouts, forks and junctions.
The next steps describe the invention workflow [Figure 4]: 1. Get the calculated route. 2. Identify the junctions the calcul...
