The SkyFox Labs piPATCH-L1E1 is a GPS-L1 + GALILEO E1 CubeSat Active Antenna module designed to provide strong signal reception in space.

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

The module fits CubeSat structures with M2.5 mounting holes. Customized mounting hole placement or additional sensors/EEE parts are available on request.

Product is manufactured in two grades to satisfy both Engineering and Flight requirements. Modules (/EM, /FM) are electrically identical, however their chemical and mechanical properties allows it to be used in laboratory or space, respectively.

The fully functional Engineering Model is finished by red coating with Remove Before Flight labelling.
