GOES-R Features that Allow Near-Continuous Observation |
Dr. Steve Jolly is the Lockheed Martin Chief Engineer for the GOES-R program (next generation weather satellites in geo-synchronous orbit) in the Civil Space line of business for Space Systems Company. He was GOES-R Chief Systems Engineer from inception through 2012. He is the Program Manager for the Mars Reconnaissance Orbiter (MRO) in flight operations, and was DPM and Chief Systems Engineer during development. He has served Project Orion off and on as an independent advisor and tiger team lead for entry, descent and landing. He was Program Manager for the Mars Science Lab (MSL) Aeroshell and was a co-inventor of the highly innovative MSL Sky Crane. He has served as a member of EDL systems engineering team and critical events risk process for Phoenix, Stardust and Genesis and served on the National Research Council’s EDL panel. He was chief systems engineer for Mars Sample Return (MSR). He was also systems design lead for Mars Climate Orbiter (MCO) and flight operations lead for the ill-fated MCO and MPL. He has 31 years of experience in spacecraft and launch vehicles from concept through flight operations. Steve was an assistant research professor of aerospace engineering sciences at the University of Colorado prior to joining Lockheed Martin and has remained active in developing and teaching courses, and publishing. He was a faculty member of the NASA Center for Space Construction, and a NASA faculty fellow of NASA Marshall Space Flight Center. Representing LM, Steve is currently Focus School Advisor to CU-Boulder and serves on the external advisory board for Aerospace Engineering Sciences. Before his academic career he was with McDonnell Douglas Astronautics building and launching Delta and Delta II vehicles. He has a B.S. in aerospace engineering from CU-Boulder, an M.S. from Florida Institute of Technology, and a Ph.D. in aerospace engineering sciences from CU-Boulder. He is a 2007 recipient of the NASA Public Service Medal for distinguished service and is the American Astronautical Society (AAS) Chair for the Rocky Mountain Section. He is a member of the board of directors for the Space Science Institute (SSI).

Abstract |
| |
The Geostationary Operational Environmental Satellite R-Series (GOES-R) satellite has the operational capability for near-continuous observation to enhance our nation’s ability to observe, predict, and communicate weather and climate data at a new level of fidelity and timeliness. GOES-R meets performance requirements while performing satellite operations like station keeping and offloading momentum wheels, and does not require a yaw flip of the satellite at any time of the year. Similarly, the fault management architecture for GOES-R is constructed around an emergent philosophy that allows for fault containment at the component level and the avoidance of unnecessary safe hold entries for the satellite. Together, these features strive toward 100% availability for this advanced weather satellite, assuring the acquisition and downlink of vital Earth and space observation data used for weather prediction. This paper discusses these advanced capabilities and how they are harmonized in the GOES-R system architecture to achieve assured observation.
