  • Publication number: 20100202495
    Abstract: A transmitter has a portion that sets a parameter about the transmitter itself based on a parameter made to correspond to a condition for selecting a receiver with which the transmitter communicate with, a portion that generates a spread code based on the set parameter, and a sending portion that spreads transmit-data to form a spread signal by the generated spread code, and that sends the spread signal. The receiver has a portion that receives the signal transmitted by the transmitter, a portion that sets a parameter about the receiver itself based on the parameter made to correspond to the condition, a portion that generates a despread code based on the set parameter, a portion that performs a correlation computation of the received signal and the generated despread code, and a portion that selects a transmitter with which the receiver communicates, based on a result of the correlation computation.

  • Publication number: 20100007550
    Abstract: A positioning apparatus for a mobile object for measuring a position at a current time includes a GPS positioning unit for updating a GPS operation data; an INS positioning unit with a detection value for INS positioning; a speed detector for detecting speed; an error corrector for correcting an error of the detection value, the position measured by the INS positioning and the speed; and a mobile object model operation unit for calculating a mobile object model; wherein an initial position is calculated using the GPS operation data, and the mobile object model operation unit measures the position to the current time when the current time coincides with a GPS updating time; and wherein the initial position is calculated without the GPS operation data, and the mobile object model operation unit measures the position to the current time when the current time does not coincide with a GPS updating time.

  • Publication number: 20090271108
    Abstract: A navigation apparatus (1) that detects a position of a movable body includes map data storage means (13) for storing map data; an autonomous sensor (12) that detects information on behavior of the movable body; inertial position determination means (10b) for detecting an inertial position-determination position of the movable body, by accumulating the information detected by the autonomous sensor (12) on a result of position determination performed using radio navigation; characteristic position detection means (10d) for detecting a characteristic position (31) that is the inertial position-determination position at which the movable body has exhibited a characteristic behavior; correction amount detection means (10e) for extracting positional information on a road position (22) corresponding to the characteristic position (31), by referring to the map data storage means (13); and position correction means (10f) for correcting the characteristic position (31) using a Kalman filter based on a condition that t

  • Publication number: 20080228395
    Abstract: A positioning device that detects a position of a mobile body with a radio navigation positioning unit includes: first and second autonomous sensors obtaining behavioral information on the mobile body; a position detecting unit obtaining an estimated position and an estimated direction by updating a detection result based on the behavioral information from the first autonomous sensor; a map data positioning unit that refers to a map data storage unit based on the estimated position and obtains a map data linked position at a predetermined distance away from a link; a direction detecting unit obtaining a cumulative estimated direction by updating the detection result based on the behavioral information from the second autonomous sensor; and a most probable position estimating unit estimating the position of the mobile body from the estimated positions and directions using the Kalman filter.
