From the project
OreSat's +/-Z end caps, the PCBs on the very ends of the satellite.
The ESI -Z End Cap is the board that "caps" the -Z end of the ESI 3U CubeSat. It protects the -Z End Card, carries two RMI3000 magnetometers, as far away from the internal OreSat magnetic noise as possible, has a L1 band GPS antenna for the OreSat GPS card, and has a cutout for the ESI POD GPS antenna.
