What kind of equipment do I need to test GPS inside a building ?

Hello MP,

You will need to bring the GPS signal into the area where you are testing the M20048-1. You can use a kit such as this:

or design something similar in order to test your installation of our module. Please let me know if you have any other concerns.

Best regards,

Hello Madhu,

While you can use a GPS repeater to see that a GPS device is functional indoors, that will not be sufficient to objectively test the performance (such as the receive sensitivity) of the device.  To do that, you will need a GPS simulator and a small anechoic chamber to shield the device from RF interference.

The GPS module might work just fine until designed into the host device, where on-board circuitry EMI might desensitize the receiver or de-tune the GPS antenna.  Have you checked that?

Labs such as ours can provide GPS testing and trouble-shooting services during the development stage to verify the design, and we also develop end-of-line production testers which will verify that the device meets performance thresholds before shipping it.
