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. Allow up to 10 minutes to capture satellites if the GPS has not been used recently.
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.
TIL 1937: My Vernier GPS or LabQuest 2 GPS shows a lot of scatter when it is at rest.
