Abstract
Our mission objective is to design an altimeter satellite that uses GNSS-reflections, which means a dedicated receiver (passive instrument) onboard the satellite. Another requirement is being competitive with conventional altimeter satellites (active instruments). The use of GNSS-reflections is feasible when the antenna is optimized for receiving weak signals. We choose a phased array antenna concept. The antenna has a large field of view (FOV) of 80â, because it will be able to steer the beam and to receive up to 12 specular points simultaneously. This means that it is possible to see a much wider area than with a conventional satellite. Furthermore the satellite will have a 10-day repeat orbit doing 143 orbits with an inclination of 99.58â at an altitude of 79,173Â km. The cost price is estimated around a 100 Million Euro.
