What We Are Doing

Since 1984, CPI has designed, developed, and implemented basic and applied science projects for various U. S. Government organizations and prime contractors. Working directly with scientists at federal agencies and large prime contractors, CPI continually meets the requirements these institutions seek through cutting edge research and state-of-the-art technology. Our strong client base of repeat customers (some of whom have been using our services for over 20 years) are a testament to the confidence clients place in the experience, skills, and capabilities of our professional scientific services.


Current and Prior CPI projects include:

Astrometry

Joint Milli-Arcsecond Pathfinder Survey (JMAPS)
The Joint Milliarcsecond Pathfinder Survey (JMAPS) is a Department of Navy (DoN) bright star astrometric all-sky survey scheduled for launch in the 2013 time frame. Mission objectives include a complete update of star positions for the 2015 epoch to accuracy levels of 1 milliarcsecond (5 nano-radians) for bright stars, as well as demonstration of a 10 milliarcsecond attitude determination capability and 50 milli-arcsecond attitude control on-orbit.

vlbi_thumb Very Long Baseline Interferomety (VLBI)
Very Long Baseline Interferometry (VLBI) is a technique being used by the United States Naval Observatory (USNO) to determine the reference frames for stars and the Earth, and to predict the variable orientation of the Earth in three-dimensional space. This information is important for frequent calibration of the Global Positioning System (GPS) to avoid drift in triangulations over time. Read more >

The Synthetic Scene Generation Model (SSGM) is a Missile Defense Agency (MDA) standard model that generates multi-phenomenology scenes used to predict what visible and infrared (IR) sensors view during ballistic missile engagement scenarios. Read more >

Sensor Calibration and Validation (Cal/Val)

GOES-13 EUVS Calibration and Early-Orbit Validation
CPI and NRL physicists provided the first validation of EUVS on GOES-13 (5-channel solar EUV sensor) using multiple sources of independent data after developing a calibration model accommodating pointing offsets, non-uniform disk emission, and band spectral shapes of the user's choosing.
