Rotator for LEO satellites

    Thanks to all for the responses. We are in an early stage of the project and your part is only to set up the antenna and RX/TX system. The communication part is done by someone else and we just know that part of it will be a high speed downlink on 13cm. To our calculations we are on the limit with a 2 m dish. So at the moment we are investigating the optimum for this setup regarding dish-size / rotator accuracy and speed / system costs. We also have to account for future developments as this institut will not be able to make a similar investment within the next 10 years.
    Anyway, further informations and reports are welcome.

    In that case, if you intend to use for professional missions I would strongly recommend a much larger dish - or X-band and a proper professional dish mount. They do come up second hand and if you have a mechanical shop then perhaps it could be refurbished. You might want to talk to TU Graz - experts in this area.
