ASTRA was born out of the vision for applying fundamental space physics knowledge to real-world problems.
Geoff Crowley, Ph.D.
CEO and Chief Scientist for ASTRA LLC
Geoff Crowley is the CEO and Chief Scientist for ASTRA LLC, a technology development company, with interests in developing technology and specialized applications for customers, performing fundamental scientific research, and sales of ground-based and space-based instruments and scientific data.
He recently led the development of a commercially available software-defined GPS receiver for space weather monitoring. This receiver measures the ionospheric total electron content (TEC) and scintillation parameters that affect communications, navigation and surveillance systems. ASTRA has deployed an array of these receivers in Alaska to map ionospheric scintillation in real-time. ASTRA has also developed several smart-phone Apps for the delivery of space weather information on Apple and Android platforms. William Shatner’s “Moving America Forward” organization recently recognized ASTRA with an entrepreneurial award during a TV show that featured their scintillation work.
Dr. Crowley has also developed an HF radio sounding system, called TIDDBIT, for mapping traveling ionospheric disturbances in the ionosphere. He is alsothe Principal Investigator on the NSF-funded Cubesat mission called “Dynamic Ionosphere Cubesat Mission (DICE)”, which launched in October 2011 on a NASA satellite from Vandenberg Air Force Base.
Dr. Crowley received his Ph.D. in Ionospheric Physics from the University of Leicester, UK, and a B.Sc. degree in Physics from the University of Durham, UK. Prior to founding ASTRA, Dr. Crowley worked in four large organizations: NCAR, AFRL (as a contractor via U.Lowell), JHU-APL and SwRI, where he performed fundamental research on various areas of space physics and space weather. He has published over 100 scientific articles on his research. He is best known for his work on the thermospheric neutral gas density at high latitudes, including his discovery of the cellular structures that occur there, and his groundbreaking modeling of high density features in the cusp region.
Dr. Crowley was a co-founder of the American Commercial Space Weather Association (ACSWA), and currently serves as Co-Chair on the Executive Committee of ACSWA.
