Testing GNSS receivers

[Jacek]

Hi

I'm looking for materials about testing GNSS receivers. What document regulates the questions of certification of GNSS receiver for aviation use? What document regulates the question of maintenance and periodical checks of receivers? I'm looking for materials according to FAA and EASA.

The certification is regulated by FAA Technical Standard Orders (TSO), or EASA Technical Standard Orders (ETSO). Generally there is little (if any) difference between them.

FAA:
TSO-129 GPS
TSO-145 GPS/WAAS, integrated avionics
TSO-146 GPS/WAAS, stand alone receiver

EASA
ETSO-129 GPS
ETSO-145 GPS/WAAS, integrated avionics
ETSO-146 GPS/SBAS, stand alone receiver

All documents above have several revisions, indicated by a letter appended to the document number.

The underlying tests for certification are specified in the Minimum Operational Performance Specifications (MOPS)
RTCA DO-208 (GPS MOPS)
RTCA DO-229 (GPS/WAAS MOPS)

(E)TSO-129 should no longer be used for new equipment .

The required maintenance & periodic checks are specified in the Component Maintenance Manual (CMM).

But if your question is about testing the navigational accuracy of a GNSS/GPS as installed in an airframe basically, per the FAA, you don't - it is not required.
You are required to verify that the antenna isn't subject to airframe blanking in banked turns and that it is not affected by VHF transmissions or any other EMI - see FAA AC 25-7C.
