GEOST sensors to detect interference will fly on SDA satellites – Breaking Defense

AFA 2023 — Northrop Grumman has tapped Tucson-based startup GEOST to provide sensor payloads to protect the missile tracking satellites the defense behemoth is building for the Space Development Agency (SDA), GEOST announced Monday.

GEOST, a LightRidge Solutions company, makes electro-optical and infrared sensors for space applications. Under the contract, the firm will supply eight tiny Starlite sensors, each about the size of a soda can, to identify ground-based sources of interference; it will also supply an accompanying ground system. The payloads will equip some of Northrop Grumman’s satellites being built as part of SDA’s first operational Tracking Layer constellation in low Earth orbit, the release said.
