Descripción
The European Space Agency (ESA) has undertaken the development of
Optical Data Relay payloads, aimed at establishing free space optical
communication links between satellites. The first of such systems put
into orbit is the SILEX project, in which an experimental link between a
GEO satellite (ARTEMIS) and a LEO satellite (SPOT IV) will be used to
relay earth observation data. In order to perform In Orbit Testing (IOT)
of these and future optical communications systems, ESA and the
Instituto de Astrofisica de Canarias (IAC) reached an agreement for the
building of the Optical Ground Station (OGS) in the IAC Teide
Observatory, which consists basically of a 1-meter telescope and the
suitable instrumentation for establishing and testing bi-directional
optical links with satellites. The presence of the atmosphere in the
data path posses particular problems, with an impact on the
instrumentation design. The transmission, reception and measurement
functions, along with the overall control of the instruments, are
performed at OGS by the Focal Plane Control Electronics (FPCE). The
design and performance of this instrumentation is presented, emphasizing
the Pointing, Acquisition and Tracking, the Tuneable Laser and the
Master Control.
