Mission-ready calibration device for in-flight RCS measurement.
The Spherical Passive-Active Radar Calibration System (SPARCS), a product for the U.S. Air Force, is a calibration device for in-flight RCS measurement ranges. This autonomous, lightweight flying sphere allows a single operator to deploy and operate the system through its guidance, navigation, and control module. This module includes a high-precision reference GPS/IMU subsystem for altitude and position control, as well as a two-way telemetry link to the ground control station.
