Abstract
Through funding by NASA’s Exploration Systems Research and Technology (ESR&T) Program and the Advanced Space Technology Program (ASTP), a team, including JPL, Boeing, NASA-Glenn, and the Georgia Institute of Technology, will develop an end-to-end modeling tool for rapid architecture trade-offs of high-datarate laser communications from lunar, martian, and outer planetary ranges. An objective of the modeling tool is to reduce the inefficient reliance on modeling of discrete subsystems or sequential development of multiple expensive and timeconsuming hardware units, thereby saving significant cost and time. This dynamic, time-domain modeling tool will accept measured component and subsystem data inputs and generate “difficult to measure” characteristics required for the performance evaluation of different designs and architectural choices. The planned modeling tool will incorporate actual subsystem performance data to reduce the develop–build–evaluate–refine production cycle. The list of high-level objectives of the program includes (1) development of a bidirectional global link analysis backbone software encompassing all optical communication subsystem parameters; (2) development of a bidirectional global link simulation model encompassing all optical communication parameters; (3) interoperability of the link analysis tool with all relevant detailed subsystem design models; and (4) a validated model that is validated against known experimental data at the subsystem and system levels.
