A hologram display device includes a light generator generating light, a spatial light modulator forming an interference pattern to interfere with the light, and a controller providing interference data to the spatial light modulator to form the interference pattern. The spatial light modulator includes a first area in which pixels are arranged in a first pattern, and a second area in which pixels are arranged in a second pattern. The controller includes a data generator generating first interference data for the first area and second interference data for the second area, a compensator generating first correction data based on the first interference data and second correction data by correcting the second interference data, and an output unit generating the interference data based on the first correction data and the second correction data.

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.

GNSS receiver and calculating method for pseudo-range and position determination thereof

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.
