The invention relates to the determination of the rotational position of a sensor by means of a laser beam emitted by a satellite. For this purpose, the sensor includes a rotational position determination device which has a laser beam detection device for detecting the laser beam emitted by the satellite. Moreover, the rotational position determination device includes a control device which is designed for determining the rotational position of the rotational position determination device based on the detected laser beam.

Determination of the rotational position of a sensor by means of a laser beam emitted by a satellite

A device configure to wirelessly transmitting optical signals via a satellite communication link includes a first sending arrangement and a first receiving arrangement. The first sending arrangement is configured to transmit optical signals via a first transmission path and a second transmission path to the first receiving arrangement. The first transmission path has a first transmission channel and the second transmission path has a second transmission channel. In addition, the first transmission channel is physically separated from the second transmission channel, while the second transmission channel is a low-rate transmission channel for transmitting amplitude-modulated optical signals.

Satellite communication link

A system for communication between two communication platforms, including a near-earth returning platform and a remote platform. A bidirectional asymmetrical communication link is set up between the two platforms.

System and method for communication between two communication platforms

A system and method for determining a position of a communication platform involves a first communication platform and a second communication platform. The first communication platform is in communicative contact with the second communication platform, and the communication connection is a focusable communication connection. The direction and/or orientation of the focusing of the communication connection is determinable and, by determining the focusing of the communication connection, a position of the second communication platform is determinable.
