Spacecraft Power Monitor, Phase I

Completed Technology Project

Project Introduction

Spacecraft Power Monitor, Phase I
This SBIR Phase I project will develop the Spacecraft Power Monitor (SPM) which will use non-intrusive electrical monitoring (NEMO). NEMO transforms the power distribution network in an spacecraft into a multiple-use service, providing not only power distribution but also a diagnostic monitoring capability based on careful measurement and analysis of power usage and start up and shut down transients. In depth analysis of this data enables real time assessment of system and component functioning and identifies potential system and component faults and failutes. We will use NEMO's ability to track load operation to verify that the systems and components of a spacecraft are operating properly This "spacecraft power monitor" or SPM, based on NEMO, will notify astronauts or ground support personnel when unexpected sequences occur. It can also generally track the health and diagnostic condition of key loads on the system. The system is light weight, small and inexpensive because the system requires only a sensor at the mains power input and uses existing power wiring to carry data. Phase I will involve ground measurements of spacecraft components. Phase II will involve measurements and analysis of an integrated system. More »
