Form 9.B Project Summary






Project Title:

Spacecraft Microaccelerometer


Technical Abstract (Limit 200 words)

Canopus Systems proposes to perform both

conceptual design and prototype test of a

spacecraft inertial sensing microsystem based upon

a unique MEMS high resolution, novel design

microaccelerometer. The innovative microsystem

design represents technologies sought by

integrating acceleration data sensors, and data

processing with high performance, low power, low

cost subsystem interfaces on a multi-chip module

using advanced packaging techniques. A conceptual

design for a real time in-situ sensor calibration and

test feature is also provided. The project objectives

are to: carry out the microaccelerometer

performance analyses and compare predicted

parameters with prototype test data; develop a

near-optimal sensor design configuration; and

perform an overall microsystem conceptual design

including control, interface and calibration


The proposed effort includes modeling, simulation,

analyses, prototype sensor test and evaluation,

preliminary system design and environmental

qualification planning. The results anticipated are

development of a recommended microsystem

design with optimized sensor subsystem features to

be implemented in a Phase II flight development

and demonstration program. Space microelectronics

systems applications will include acceleration

measurements for IMU's, structural analyses,

microgravity science, in-space propulsion and

related inertial sensing functions to significantly

reduce the spacecraft's power, mass, volume and

cost requirements via MEMS and microsystem


Potential Commercial Applications (Limit 200 words)

The microaccelerometer microsystem can be

utilized for acceleration environment

characterization (structural modeling verification,

microgravity science process disturbances) on

commercial payloads flying on Shuttle, Space

Station and free flyer platforms. The design can

also be utilized in inertial measurement units

installed in commercial spacecraft, in military

avionics, in commercial and civilian avionics and in

personal or mobile navigation sensor microsystems.

The system can also be utilized in seismometry for

commercial oil exploration.
