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.
