The SkyFox Labs piPATCH-MAX is a Multiband (Civil GPS-L1 + GLONASS-G1 + GALILEO-E1 + BEIDOU-B1) Satellite Active Antenna module designed to provide strong signal for GPS satellites reception in space.

The module is suitable for projects requiring stronger GPS signal reception with enough margins due to the ease-of-use MCX signal and power interface.

The module could be easily mounted to the satellite structure using four M4 screws with a flat head. High quality conformal coating, Kapton fix and Sn/Pb tin-lead (non-RoHS) used for the Flight Model by design brings the best possible outgassing performance in vacuum environment of space.

The antenna is fully compatible with piNAV-L1, piNAVi-L1 and pqNAV-L1 GPS navigation solutions as well as other GPS/GLONASS receivers with biased RF antenna inputs in the nominal range of 3.3V to 5V DC.
