A Legacy of Space Innovation for Sixty YearsExtensive Space HeritageMicrochip’s Vectron state-of-the-art crystal manufacturing facilityin Mt. Holly Springs, PA employs some of the most experiencedfrequency control personnel in the industry. Today, we drawon the expertise of these individuals to supply precision quartzcrystals and blanks to our military, space, defense and commercial customers, utilizing state-of-the-art design, manufacturingand control systems to meet and exceed customer expectationsfor reliability, performance and value. Vectron brand oscillators,consist of products from several acquisitions, including VectronInternational, McCoy Electronics and Oak Frequency Control.When the world celebrated the 50th anniversary of the Apollo 11moon landing in 2019, it was due in part to the McCoy Electronics frequency control products that were onboard the lander. Priorto the Apollo program, our products were onboard the UnitedStates’ first successful space exploration mission in 1958.Solutions From Low Earth Orbitto Interstellar SpaceFor over six decades, Vectron’s products have flown in hundreds of missions. Our products are currently in low earth orbit,geosynchronous orbit and on the Moon, Mars and Venus.Voyager 1, the furthest man made object from the earth, hasfrequency control products that have operated continuouslyfor 42 years, and are aiding in the transmission of data frominterstellar space, a distance of 13 billion miles. The followingchart highlights some of the major programs that have usedVectron oscillators.Continuous InnovationWith over six decades of proven flight heritage, we draw onour experience and continue to innovate, providing state ofthe art designs, world class manufacturing and unparalleledcustomer service to assist your space mission success nowand into the future.Highlights of Major Programs Using Vectron ce Shuttle1990sCentaurCassini-HuygensHubble TelescopeInternational Space Station2000sMars SpiritMars OdysseyNew HorizonsGlobal Star II2010sOrionGPS IIIGalilieoAtlas IV launch vehicleVectron Space and High-Reliability Frequency-Control Solutions3
