Summary
INMARSAT 5-F1 is a communication satellite with the NORAD catalog ID of 39476 and object identifier 2013-073A, built by BOES using the BSS-702HP bus configuration for INMRL (Inmarsat). Launched on December 8, 2013, from TYSMC LC200/39 aboard a Proton-M/Briz-M launch vehicle, this satellite reached its stable orbit on December 9, 2013. It has dimensions of 7 meters in length, 3.2 meters in diameter, and spans 33.8 meters when solar arrays are deployed. The dry mass is 3500 kilograms, and the launch mass was 6090 kilograms. Equipped with 89 Ka-band transponders for communication purposes, it uses two deployable solar arrays along with batteries for power supply. Its design includes a box shape with two panels for its solar arrays, and it has an expected operational lifetime of 15 years.
