20100149037 | Global positioning system (GPS) receiver and method of determining location of GPS receiver - A Global Positioning System (GPS) receiver includes a GPS receiving unit configured to receive navigation data from at least one visible satellite, a decoder configured to decode the received navigation data to extract time and almanac information from the decoded navigation data and a database configured to store satellite disposition information. A satellite location determining unit is configured to select at least one visible satellite candidate using the time information and the satellite disposition information, and to determine locations-in-space of the at least one visible satellite candidate with the almanac information. Also, a navigation filter is configured to calculate pseudo-ranges from the at least one visible satellite and the selected at least one visible satellite candidate using the corresponding locations-in-space, and to determine a location of the GPS receiver using the calculated pseudo-ranges. | 06-17-2010 |
20100207814 | Global positioning system receiver and satellite clock correcting method thereof - Disclosed is a global positioning system receiver which comprises a satellite signal receiving part constructed and arranged to extract navigation data from a satellite signal received from at least one satellite; a decoder constructed and arranged to decode the navigation data; a satellite location determining part constructed and arranged to determine a location of the at least one satellite according to the decoded navigation data; and a satellite clock correcting part constructed and arranged to calculate a velocity of the at least one satellite and to correct a satellite clock based on at least one of the calculated satellite velocity and the location of the at least one satellite. | 08-19-2010 |
20120206294 | Samsung Electronics Co., Ltd. - A Global Positioning System (GPS) receiver includes a GPS receiving unit configured to receive navigation data from at least one visible satellite, a decoder configured to decode the received navigation data to extract time and almanac information from the decoded navigation data and a database configured to store satellite disposition information. A satellite location determining unit is configured to select at least one visible satellite candidate using the time information and the satellite disposition information, and to determine locations-in-space of the at least one visible satellite candidate with the almanac information. Also, a navigation filter is configured to calculate pseudo-ranges from the at least one visible satellite and the selected at least one visible satellite candidate using the corresponding locations-in-space, and to determine a location of the GPS receiver using the calculated pseudo-ranges. | 08-16-2012 |
20140152496 | GNSS RECEIVER AND CALCULATING METHOD FOR PSEUDO-RANGE AND POSITION DETERMINATION THEREOF - Methods and apparatus are provided for calculating a pseudo-range and position in a global navigation satellite system receiver. A first pseudo-range of a satellite is calculated for position determination of the global navigation satellite system receiver. A second pseudo-range of the satellite is calculated for position correction of the global navigation satellite system receiver. A differential operation is performed using the first pseudo-range and the second pseudo-range to eliminate an error. A more precise pseudo-range of the satellite is calculated using the differential pseudo-range. | 06-05-2014 |
