Full Summary
URSALA, RAQUEL, and FARRAH are small satellites developed by the National Reconnaissance Office (NRO) to collect electronic intelligence (ELINT) data. Initially designed in response to emerging threats, these satellites transitioned from serving national intelligence to providing real-time data for tactical military forces.
URSALA focused on detecting radar signals in the 2 to 12 gigahertz range, while RAQUEL utilized a directed search method for specific targets. Four URSALA satellites were launched between 1972 and 1979, with lifetimes extending beyond their expected durations.
The success of these satellites led to the Tactical Exploitation of National CAPabilities (TENCAP) program, allowing direct access to intelligence data for military users. This shift marked a significant evolution in how intelligence was gathered and utilized in combat scenarios.
