  • Method and system for determining relative displacement and heading for navigation
    Patent number: 8954271
    Abstract: A system and method for determining a location of a mobile object is provided. The system determines the location of the mobile object by determining distances between a plurality of sensors provided on a first and second movable parts of the mobile object. A stride length, heading, and separation distance between the first and second movable parts are computed based on the determined distances and the location of the mobile object is determined based on the computed stride length, heading, and separation distance.
    Type: Grant
    Filed: November 8, 2010
    Date of Patent: February 10, 2015
    Assignee: The University of Maryland, College Park
    Inventors: Suneel Ismail Sheikh, Darryll J. Pines, Joseph Kim Conroy, Timofey N. Spiridonov

  • Navigational system and method utilizing sources of pulsed celestial radiation
    Patent number: 7197381
    Abstract: A system and method for navigation utilizing sources of pulsed celestial radiation are provided. A spacecraft, satellite, or other vehicle (12) has a pulse sensor (22) mounted thereto for detecting signal pulses (14) generated by a plurality of pulsars or other celestial objects (16). The detected signal pulses (14) are synchronously averaged at the known period of the pulsar or other celestial object (16) with respect to a timer (24). Timer (24) measures the pulse time of arrival at the pulse sensor (22) by comparing the pulse signal (14) with a pulse shape template (52), and a processing means (30) calculates the offset time between the measured pulse time of arrival at sensor (22) with a calculated pulse time of arrival at the solar system barycenter (SSBC).
