We are only relying on the currently connected to radio-cell to estimate a position and it can take up to 20 seconds until a first position estimate from the network is obtained. The likely difference with android for example is that we do not hand information about neighboring radio cells to the network-based positioning provider.
Also note that applications have no way of forcing the system to use this information (on purpose). The location infrastructure will make sure that all required providers to achieve a fast and accurate fix are powered on whenever an application requests position updates. I will come up with actual measurements of the time it takes to obtain a position estimate after updates have been enabled. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to location-service in Ubuntu. https://bugs.launchpad.net/bugs/1500039 Title: Ubuntu Phone is not getting a mobile network cell triangulation position Status in Canonical System Image: Confirmed Status in location-service package in Ubuntu: Confirmed Bug description: Hi! I think that the mobile network cell triangulation position is not working in Ubuntu Phone OS. The position should be really fast (~1 - 5") and I'm thinking that Ubuntu Phone is waiting for a real GPS position every time. A good test could be this: - Go to a room, way out of a sky to avoid a real GPS signal. - Set WiFi service OFF. - Set GPS service ON. - Set data connection ON. - Go to this website via webbrowser-app: http://leafletjs.com/examples/mobile-example.html The website will ask you to allow access to the current location. - Make sure to not have a GPS position cached. In a PC or *any* Android you'll see your position immediately. Bug: In Ubuntu Phone an error will appears. This error is because the geoposition (https://developer.mozilla.org/en-US/docs/Web/API/Geolocation/Using_geolocation) is not working with the cell triangulation network data. You can try a lot of apps like Google Maps, OSMTouch, HERE map, uNAV... and a fast position from data connection is not happening, unless you be with a WIFI connection. If you try Google Maps in Android, the position will be really fast just with data connection. Thanks in advance!
