Summary
NAVSTAR 44 (USA 135), also known as GPS IIA-19, is a US navigation satellite that was launched on November 6, 1997, from Launch Pad LC17A at AFETR using the Delta 7925 launch vehicle. It operates as part of the GPS constellation and has a configuration of 3-Axis stabilization with a box shape plus two panels. The satellite measures approximately 2.4 meters in length, 1.8 meters in diameter, and spans 5.3 meters when its solar arrays are deployed. Its dry mass is 860 kg, which is the same as its launch mass. It was manufactured by BOSB and equipped with two deployable solar arrays for power generation along with batteries. The satellite's intended operational lifetime was estimated to be around 7.5 years, serving navigation purposes under the ownership of AFSMC.
