One time glitch after lost gps signal

[Herman Veldhuizen]

This showed up on the map, have only seen it once. It happened after driving through a tunnel (no gps).
5.2.1 on Android.

The sign in the upper left corner says you dont have an internet connection

@Marinus-van-Deudekom no, it means that i am driving in forest like area (offroad), and HERE thinks that because it got an incorrect position from my phone (lost the gps signal). It takes a little while to recover from that.

The patch work of blue lines is roughly on a straight line between to waypoints.

@Herman-Veldhuizen now I see the fault in my answer. It shoot have been no internet connection instead of what I wrote an internet connection. Small detail nog difference

@Marinus-van-Deudekom It’s not an internet connection issue, but rather the GPS signal being lost when driving through a tunnel (see the original post).

@herman-veldhuizen I’ve driven through quite a few tunnels myself this summer, but I haven’t noticed this issue. Does MRA automatically pick up the route again after a while? And what happens if you tap “Tap to recalculate route”?

[Herman Veldhuizen]

@CD130 After leaving the tunnel a new gps fix was obtained in this case, but the map remained frozen, sort of. I didnt wait long enough to know if the app would recover by itself. I tapped recalculate and that worked.

[CD130]

Okay, clear. I’ll keep a closer eye on what the app does on my end when I come out of a tunnel where the GPS signal was lost.

The behaviour varies from tunnel to tunnel. Not sure why.
Most annoying is that the app recalculates if the gps position wanders off, even with the setting for automatic recalculation off.

It depends on the responsible Service Organisation for the specifically Tunnel. Some have installed antennas or other technical solutions to extend the satellite signal into the tunnel.

The it depends also on the Navi-Devices. Some uses this extra service (if it is there), some does an interpolation, to keep on to display the position on the screen, some does nothing then informing about loss of GPS signal.
