Experiment Computer System for Spaceflight Payload Command & Control, Laser Metrology System for Deployed Structure Verification, and General Purpose

The goal of the Phase II program is to expand the development of the fault-tolerant, general-purpose Experiment Computer System (ECS) and Laser Metrology System (LMS) from the feasibility study of Phase I and concurrent Phase II activities to Engineering Development Unit (EDU) level applicable to the Deployed Structures (DSX) flight experiment. The program consists of three main efforts. The first is development of a prototype Experiment Computer System (ECS), which serves as the sequencer for deployment control as well as handling command, control and data acquisition functions for DSX. The second is development of a laser metrology sensor (LMS) that will provide precise angular and range measurements of structural deflections of the DSX deployed structures. The third develops an active isolator concept for one of the large, flexible DSX payloads.
