Abstract [en]

This work presents the design aspects of Miniature Optical Ground Station (MOGS)for free-space communication links. Proposed MOGS terminal shall establish and sustainfast and reliable free-space data transfer link between the space, airborne andground platforms. MOGS terminal consists of agile and accurate two axis pointing (elevation,azimuth) and tracking mechanism, optical transmitter (Tx) and receiver (Rx)systems and supporting hardware and software. MOGS system shall be mechanicallysound, dust and water protected and light weight to be transported by two people.Design requirements consider the operation of MOGS in hostile environmental conditionssuch as operation under the heavy rain, humidity, dust storm, long exposure todirect sun and temperature variations. The design of MOGS is a complex combinationof mechanics, electronics and optics. The tight budget, high demanding performancerequirements and week defined or conflicting (for different missions) customer specificationsadds complexity in the design process. Initial research showed that one system willhardly be able to meet the requirements for all the variety of possible mission scenarios.Alternatively, one could think about a design which allows adaptation in some extentand can be customized for specific mission. In the scope of this thesis we highlightthe MOGS high level and subsystem level configuration trade-offs and design variables.The work is mainly focused on the MOGS structural configuration , receiver optics andpointing, acquisition and tracking (PAT) systems.
