When lat / lon becomes (0,0) in GeoCoordinateWatcher

I am in trouble because there are many cases where the latitude and longitude cannot be obtained with GeoCoordinate Watcher.

Specifically, the following acquisition results are often obtained.

(conditions)
・ Model: Surface GO 2 (LTE model)
・ GPS = ON / LTE = No Sim / Wifi = OFF
・ GeoPositionAccuracy = default

(State in PositionChanged event) * 1
・ (GeoCoordinateWatcher) .Status! = GeoPositionStatus.Ready
・ (GeoCoordinateWatcher) .Position.Location.IsUnknown = false
・ (GeoCoordinateWatcher) .Position.Longitude (Latitude) = 0

In the case of " 1", what kind of hardware state can be considered?
Example)
・ GPS module: Obtained but GPS signal is incorrect
・ GPS module: Not acquired
・ GPS module: Acquiring
If the signal has not been acquired, I think it will be "Is Unknown = true".

Also, if the signal is received purely by the GPS module (LTE = No Sim / Wifi = OFF), how long does it generally take to make a decision? (GeoPositionAccuracy = default)

Thank you
