The GPS requires an open view of the sky to work well; it is not designed to work indoors. The most likely reason for not seeing satellites is poor view of the sky.

To test the GPS, take it outside and position it with a clear view of the sky with the screen facing up. It can take 15 minutes or more to capture satellites if the GPS has not been used recently. You need to acquire signals from at least three satellites before your position is shown in the LabQuest App.

LabQuest 2 only
The number of satellites acquired by the GPS can be viewed by tapping the globe symbol in the lower-right of the LabQuest 2 screen. When LabQuest is searching for satellites but is not communicating with enough to establish a location, there is an X over the globe symbol.

LabQuest 3 only
The number of satellites acquired by the GPS is shown to the right of the GPS icons shown in the top notification bar.
