    摘要： An SPS receiver comprises a radio receiver for measuring pseudoranges to orbiting SPS satellites, a local real time clock accurate within three seconds of true SPS system time, and a communication channel to receive NAV-data rebroadcasts from a server. Such server is associated with its own private navigation receiver that has direct satellite signal reception that is strong enough to reliably demodulate the SPS system NAV-data. The SPS receiver synthesizes its own NAV-data from time information provided by the local real time clock and almanac and ephemeris data provided by the server in the rebroadcast. Thus the SPS receiver can operate in weak signal environments that would otherwise be impossible.

    摘要： A navigation-satellite receiver uses a reference station accessible over a network to store NAV data subframes for pattern matching at a network client. Alternatively, the pattern matching is performed by the server when per-byte communication costs are high. The stored NAV data repeats ephemeris data every thirty seconds, and full almanac data every 12.5 minutes. This permits the client to instantly recognize where in the NAV data sequence its own received signals are, and it need not actually wait to receive the preambles in the TLM words. Several precious seconds are therefore saved in producing a rapid time-to-first-fix.

    摘要： A time difference information supply system includes: a terminal unit for receiving satellite signals as signals from positioning satellites; and a plurality of communication base stations asynchronous with one another, which can communicate with the terminal unit and include base station time measuring means for measuring time of the communication base stations, transmission information producing means for producing transmission information containing transmission time, and transmission information transmitting means for transmitting the transmission information to the terminal unit on transmission radio waves. The terminal unit includes: distance information storing means for storing distance information indicating distances between the terminal unit and the communication base stations with which the terminal unit can communicate; satellite time synchronizing means for maintaining synchronicity with time of the positioning satellites based on the satellite signals from the plural positioning satellites; transmission radio wave receiving means for receiving the transmission radio waves from the plural communication base stations simultaneously or sequentially, reception time information producing means for producing reception time information indicating reception time of the transmission radio waves; communication base station distance acquiring means for acquiring distances between the terminal unit and the communication base stations from the distance information storing means; estimated reception time information producing means for producing estimated reception time information indicating estimated reception time of the transmission radio waves based on the transmission time contained in the transmission information and the distances between the terminal unit and the communication base stations; transmission time difference information producing means for producing transmission time difference information indicating differences of the transmission time based on the reception time information and the estimated reception time information; and transmission time difference information storing means for storing the transmission time difference information of the plural communication base stations.

    摘要： A slice set for a specific period of time is acquired from a storage area of a memory which is a ring buffer while changing the read position, and the signal strength total value of each slice set is calculated. The signal strengths of the slices include in the maximum strength slice set and the signal strengths of the slices preceding or subsequent to the maximum strength slice set are calculated, and the final signal read position is determined based on a read offset of the maximum strength slice. A GPS satellite signal is acquired and tracked based on the slice read from the determined signal read position, and a specific positioning process is performed.
