Abstract: Operationally Responsive Space (ORS) has become the mantra for the next generation spacecraft that will support the warfighter. ORS missions require an extension of the current, traditional approach for fine-tuned, high cost, high accuracy attitude...
Abstract: The concept of utilizing pulsars for spacecraft navigation has been in development since the discovery of these rapidly rotating neutron stars in the 1960’s [1]. The Jet Propulsion Laboratory (JPL) conducted studies in the 70’s and 80’s proposing the use of...
Abstract: Functional and design concepts, and a number of promising scenarios for use of a low-cost, simple Orbital Transfer Vehicle (OTV) are presented in this paper to help provide the rationale for developing such a vehicle for near-term use in supporting and...
Abstract: In-flight demonstration of close-range formation flying modes is discussed with emphasis on low cost, based on spacecraft design simplicity and minimum size, and hence minimum launch cost. Piggy-back launch of three identical demonstration spacecraft is the...
Abstract: AttSim is a spacecraft attitude simulator that has been specifically developed to design and verify attitude control concepts and flight software architectures and algorithms. Its primary goal is to provide a generic approach to small satellite attitude...
