Summary
NAVSTAR 9 (USA 1), also known as GPS 9, is a navigation satellite launched by the US Air Force Space Command (AFSD) on June 13, 1984, from Vandenberg AFB's Space Launch Complex 3W using an Atlas E/SGS-2 launch vehicle. This GPS satellite has dimensions of 2.4 meters in length and 2.6 meters in diameter with a span of 5.3 meters. It weighs 431 kilograms at dry mass and was designed to last for approximately five years. The satellite's shape is described as a box with two panels, equipped with deployable solar arrays and batteries for power generation. Its mission focuses on navigation purposes within the GPS constellation, and it uses a 3-axis stabilized configuration manufactured by RWISB. NAVSTAR 9 is associated with the Payload GPS SVN 9 and operates without specified transmitter frequencies or major events noted in its record.
