Question

I’ve been looking quite some time today to gather GPS coordinates from a Windows Phone 7 device – however since I do not have an actual test device here I tried to set some dummy data which I want to have returned instead of real GPS Data … that, however ist not working out too well:
This code ist partially an example from so which I found here. However I tried to put it into a class which I can access later.

public class GetGPS : GeoCoordinateWatcher
{
    GeoCoordinateWatcher watcher;

    public GetGPS()
    {
        watcher = new GeoCoordinateWatcher(GeoPositionAccuracy.Default);
        watcher.MovementThreshold = 20;

        watcher.PositionChanged += this.watcher_PositionChanged;
        watcher.StatusChanged += this.watcher_StatusChanged;
        watcher.Start();
    }

    private void watcher_StatusChanged(object sender, GeoPositionStatusChangedEventArgs e)
    {
        switch (e.Status)
        {
            case GeoPositionStatus.Ready:
                //plingpling
                break;
            case GeoPositionStatus.Disabled:
                // location is unsupported on this device
                break;
            case GeoPositionStatus.NoData:
                watcher.Position.Location.Latitude = 54.086369f;
                watcher.Position.Location.Longitude = 12.124754f;
                break;
        }
    }

    private void watcher_PositionChanged(object sender, GeoPositionChangedEventArgs<GeoCoordinate> e)
    {
        var epl = e.Position.Location;

        // Access the position information thusly:
        epl.Latitude.ToString("0.000");
        epl.Longitude.ToString("0.000");
        epl.Altitude.ToString();
        epl.HorizontalAccuracy.ToString();
        epl.VerticalAccuracy.ToString();
        epl.Course.ToString();
        epl.Speed.ToString();
        e.Position.Timestamp.LocalDateTime.ToString();
    }
}

This is my other class in which I try to access the data – however I always get NaN as lat1Rad and long1Rad … can you please help me?

I want that example to be functional on the emulator ( with a fixed GPS Coordinate ) and on a phone 7 device – where it actually grabs the value.

GetGPS location1= new GetGPS();

//GeoCoordinate myPosition = location1.getPosition();

//Radianten berechnen
double lat1Rad = GradZuRad(location1.Position.Location.Latitude);
double long1Rad = GradZuRad(location1.Position.Location.Longitude);

I basically just want to program a class which returns me the CURRENT GPS Position.

Where is your example code from?

Have you tried using the sample on MSDN?

Alternatively, there’s a greate simulator available from http://phone7.wordpress.com/2010/08/02/no-device-no-gps-no-matter-with-code/
