Key highlights

The SkyFox Labs miniPATCH-L1 is a GPS-L1 CubeSat active antenna module designed to provide strong signal for GPS satellites reception in space.

The module can be embedded closer to the conductive parts such as metallic sidewalls or PCB groundplanes on the body of the satellite to extend the existing antenna groundplane. The module is suitable for projects requiring stronger GPS signal reception with enough margins and ease-to-use MCX signal and power interface.

Product is manufactured in two grades to satisfy both Engineering and Flight requirements. Both the 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.
