    摘要: A navigation method includes imaging a first celestial object (12) with an imaging device (102)and calibrating the pointing of the imaging device (102) to position of the first celestial object (12) in the image. A second celestial object (12) and a satellite (20) are imaged and position of the platform (22) determined using position of the conjunction of the second celestial object (12) and the satellite (20) in the image of the second celestial object and satellite. Navigation systems are also described.

    摘要: The invention provides an autonomous navigation method of Mars probe. The method comprises the following steps: according to the position relationship of the probe in the solar system, selecting the sun, the earth and the sun, Mars as the observed objects, acquiring the angle information, and establishing the position, velocity and other navigation parameters with the extended Kalman filter (EKF). The invention has the advantages of simple principle and low system resource requirements; it is a new method of autonomous celestial navigation of the Mars probe. The method expands the spacecraft navigation means, improves the navigation ability, and can be directly applied to the future autonomous navigation mission of Mars exploration in China; therefore, it has a wide range of applications in the field of deep space exploration.

    摘要: A large constellation of low-cost satellites with a satellite support and administration system that allows widespread user access to advanced satellite technology at extremely low costs. Any portion of the constellation can be tasked and configured for specific data capture. In one embodiment, a constellation of individual satellites are employed to concurrently collect occultation data from multiple GPSS originating signals that pass through atmospheric sections of interest. Alternately, the constellation can be configured as a vehicle location tracking system that receives multiple vehicle tracking signals and based thereon, track within a system grid each vehicle under surveillance. The system can use AIS for ocean going vessels, ADS-B for aircraft, and AEI for trains. Use of the system permits extended tracking of key cargos and the protection of vehicles from piracy and the like.

    摘要: A method and system for a multi-spectrum celestial navigation system includes a first sensor responsive to at least a first and a second wavelength band of electromagnetic radiation. The sensor is configured to generate a first output related to the first wavelength band of electromagnetic radiation and to generate a second output related to the second wavelength band of electromagnetic radiation. The system also includes a processor programmed to receive the first and second outputs, determine a position of the sensor with respect to one or more stars using a stored star catalog and the received first and second outputs, and output the determined position.
