How a circular array of sensors catches fleeing satellite signals
In short: Tracking satellites in orbit is a race against speed and precision. This video explores SARAS, a Spanish technology designed to help ground stations lock onto signals from newly launched missions with unprecedented accuracy.
SARAS, which stands for 'Fast Acquisition of Satellites and Launchers,' solves the difficulty of capturing signals from fast-moving spacecraft. The system utilizes a circular array of eight small radio-frequency sensors mounted around the rim of a 15-meter diameter dish antenna at the ESA's ESAC Establishment.
Since its installation in 2013, the technology has been validated across numerous missions, including CryoSat-2, XMM, GOCE, and Swarm. In addition to individual objectives, the technology excels at capturing data from various satellite constellations, including the three-unit Swarm project.
