Summary

NAVSTAR 80 (USA 309), also known as GPS III SV04, is a navigation satellite launched by the U.S. on November 5, 2020, from Cape Canaveral Air Force Station's LC40 launch pad using a Falcon 9 launch vehicle. It has dimensions of 3.4 meters in length and 1.8 meters in diameter, with a span of 14 meters due to its deployable solar arrays. The satellite has a dry mass of 2160 kg and was launched with a total mass of 4400 kg. Manufactured by LMSSD for the SMC (Space and Missile Systems Center), it is designed to serve a navigation mission and operates with an AOCS motor system for its attitude control. Its power generation relies on two deployable solar arrays along with batteries, supporting its mission over a projected 15-year lifetime. The satellite's shape is described as box-shaped with two panels, and it carries the GPS SVN 77 payload to enhance global positioning services.
