Summary

The ORBCOMM-X satellite, also known as Orbcomm-X, has the NORAD catalog ID 21576 and was launched on July 17, 1991, from ELA2 at FRGUI using an Ariane 40 launch vehicle. The spacecraft is owned by ORBC and manufactured by FAIR (Fairchild Space & Defense Corporation). It has dimensions of 0.2 meters in length, 0.5 meters in diameter, and a span of 4.4 meters due to its antennas, with a dry mass of 17 kg, the same as its launch mass. The satellite is equipped with an Orbcomm payload for experimental machine-to-machine (M2M) and Internet of Things (IoT) communication purposes, powered by solar cells and batteries. Its shape is described as a box with attached antennas, and it has a radar cross-section (RCS) of 0.141 square meters. The purpose of ORBCOMM-X aligns with its mission to explore experimental communication technologies for M2M/IoT applications.
