"The pipe is being closed" error when using GeoLocator in Windows Store App(Windows 8.1)?

I am working in Windows 8.1 app and I am finding the current location of the user using below mentioned code. Now when I run my app in Tablet using Cellular network the app crashes but it works fine on Wifi. Can someone suggest a solution for this?

            geolocator = new Geolocator();
            geolocator.DesiredAccuracy = PositionAccuracy.Default;
            geolocator.DesiredAccuracyInMeters = 1000;
            geolocator.MovementThreshold = 5;
            geolocator.ReportInterval = 500;
            try
            {
                Geoposition mygeoPosition = await geolocator.GetGeopositionAsync();
            }
            catch(UnauthorizedAccessException ex)
            {
                UserMessageUtil.ShowMessage("Location is disabled in Settings");
                await Launcher.LaunchUriAsync(new Uri("ms-settings-location:"));
            }
            geolocator.PositionChanged += geolocator_PositionChanged;

I always check in Laptop Machine so I didn't face this issue in past but now I have a tablet with both 3G and WIFI connectivity and when I run the app in tablet and try to get the current location, the error comes.

Update

I also sometimes get The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) error on line

Geoposition mygeoPosition = await geolocator.GetGeopositionAsync();

I get both these error when I am connected on a Cellular network

Start off by using a larger movement threshold. Most GPS devices only have an accuracy of 15 meters. Setting the movement threshold to 5 could be too small and cause issue.

Also look at using one of the position accuracy enumerators:

geolocator.DesiredAccuracy = Windows.Devices.Geolocation.PositionAccuracy.high;
