A method for adjusting a radiation direction of an optical communication signal between a communication platform and a remote station includes: starting from an initial position of a beam deflection unit of the platform for steering the optical communication signal, adopting deflection positions of the beam deflection unit along two different lines of movement and in opposite directions along the lines of movement, the deflection positions being consistent with deflection angles having the same absolute value, each deflection position being held for a different period; measuring an intensity of the signal at the station; when an intensity change in the signal is discovered at the station, ascertaining a signal quality change in the signal and recording the duration of this intensity change; determining that intensity change that pertains to the best signal quality change, and the associated duration; changing the intensity of a guidance beam for the duration previously determined.

Beam orientation in unidirectional optical communication systems

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.

System and method for determining the position of a communication platform

To measure and regulate temperature, a temperature measuring resistor and a control element are accommodated in one layer as metallization on a substrate. The printed or otherwise manufactured conductors of the temperature measuring resistor and of the control element are arranged in close proximity to one another.

Arrangement for temperature monitoring and regulation

An optical waveguide has a core, wherein the core is doped with laser-active ions, and also additionally doped with Ce.

Optical waveguide

A device for loading of a light wave guide formed as a fiber with exciting energy in form of a pump light supply for producing a laser light has a fiber, such as a laser fiber and an amplifier fiber, which is wound with at least one winding in a coil-like manner for a transverse coupling of exciting pump light.
