Summary
IRIDIUM 123, also known as Iridium Next SV123, is a communication and traffic monitoring satellite operated by IRIDS. Launched on June 25, 2017, from Vandenberg Air Force Base (SLC4E) using the Falcon 9 launch vehicle, it was manufactured by OATKGA with a design lifetime of 10 years but planned for up to 15 years of operation. The satellite features a LENGTH of 3.1 meters, DIAMETER of 1.5 meters, and SPAN of 9.4 meters. It has a dry mass of 700 kg and was launched with a total mass of 860 kg. Equipped with L-band payload, Ka-band cross-links and downlinks, ADS-B payload, and an AIS-receiver (on 58 satellites), IRIDIUM 123 utilizes two deployable solar arrays and batteries for power. Its shape is described as a Half Hex Prism+2 pan, without specific details on its color or RCS value.
