CPS Technologies Corporation (Nasdaq: CPSH) announces the completion and shipment of several parts to be used in the high-performance spectrometer-based methane sensing system of the MethaneSAT satellite program. MethaneSAT is designed to locate and measure methane from human sources worldwide with much higher sensitivity and spatial resolution and with a far wider field of view than is available with current satellite technology. Methane is a potent greenhouse gas, with more than 80 times the warming power of carbon dioxide during the first 20 years after it is released to the atmosphere.

Grant Bennett, President and CEO, stated “CPS is pleased and honored to be participating in this historic program. The MethaneSAT program could have a major impact on significantly reducing the unnecessary release of Methane into the atmosphere. We are also pleased that participation in this program has allowed us to work with Ball Aerospace, the primary flight system integrator and instrument provider for the MethaneSAT program.”

AlSiC is a metal-matrix composite consisting of the metal aluminum and the ceramic silicon carbide. In power modules and power supplies, as well as many other electronic applications, AlSiC enables higher reliability and higher performance as a result of its material properties, particularly thermal expansion, thermal conductivity and stiffness-to-weight ratio. AlSiC is very light weight, which is an important consideration in space-based and airborne applications.

In addition to the MethaneSAT system, CPS AlSiC components are also found on the Mars 2020 Perseverance Rover, International Space Station and in the most recent generation of GPS satellites (GPS III) for the U.S. Space Force. CPS believes AlSiC components will increasingly be used in space-based and airborne applications because of the compelling performance advantages AlSiC provides.
