Minimize PRARE Sensor Description

PRARE (Precise Range And Range-Rate Equipment) is a microwave tracking system operating at centimeter accuracy levels for the measurement of satellite to ground range and range rate. The concept is based on an autonomous spaceborne two-way and dual frequency microwave tracking system with its own telemetry, telecommand, data storage, timing and data transmission capabilities. This allows data analysis on a global basis within a very short time delay. Due to the microwave transmission concept, the system operates independently from weather and daylight conditions.
