LeoLabs Space Radar

LeoLabs Space Radar is operating in S-Band phased-array radar which can monitor various space objects in low-Earth orbit (e.g., satellites, space debris, rocket bodies, space stations). The radar forms a very narrow antenna pattern, which is swiveled in two elevation angle planes simultaneously. A reflecting object must pass through both antenna pattern planes. The velocity and the orbit are calculated from both measured values.

The data is fed into a network. This network currently consists of 4 large radars:

The Costa Rica Space Radar is operational since April 1. 2021. It forms a total of 4 planes of antenna patterns, which are arranged crosswise. This improves the accuracy of the measurement even for overflights with unfavorable approach angles.
