York Space Systems clears design review for Tetra 3/4 GEO space domain awareness missions
YSS•York Space Systems’ Tetra 3 and 4 missions for U.S. Space Force cleared delta Critical Design Review, allowing work to proceed to build, with spacecraft delivery targeted for Q4.
1. Design review cleared
York Space Systems expanded its prime integration work into geostationary orbit for the U.S. Space Force’s Tetra 3 and 4 space domain awareness demonstrations. The spacecraft development integrates sensors for resident space object tracking and rendezvous and proximity operations, including long-wave infrared imaging, LiDAR ranging to 20 kilometers and a GPS side-lobe receiver. A propulsion system added late in design required minor harness and software changes, with no structural, thermal or power impacts.
