Abstract: The term XNAV (X-ray navigation) is used to describe a variety of means of using celestial X-ray source observations for spacecraft attitude, position, velocity, and time determination. Several classes of source observations can be utilized for different...
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: Microcosm’s patented Orbit Control Kit (OCK) derives from the company’s long-term commitment to transfer to the spacecraft, from the ground, those operations that are better performed by an on-board system. This approach will lead to efficiencies in ground...
Abstract: Interest in studying the possibility of extraterrestrial life has led to the re-emergence of the Red Planet as a major target of planetary exploration. Currently proposed missions in the post-2000 period are routinely calling for rendezvous with ascent...
Abstract: A simulation environment is developed that will propagate a controlled orbit about asteroid and cometary bodies in the solar system. This simulation allows as input the location and orbit of the central body, and includes models for the gravitational field,...
