    摘要: Provided is a position information providing system which can reduce a time required for acquiring position information. An indoor transmitter is adapted to provide position information by using a second positioning signal compatible with a first positioning signal which is a spread spectrum signal from each of a plurality of satellites. The indoor transmitter includes an EEPROM which stores therein position data for identifying an installation location thereof, an FPGA operable to generate a second positioning signal including the position data as a spread spectrum signal, and a transmitting section operable to transmit the spread spectrum signal. The second positioning signal is generated to repeat the same content in a cycle shorter than that of the first positioning signal.

    摘要: Positional information is provided at a place out of reach of radio wave. The process executed by a positional information providing apparatus includes the steps of: obtaining a received positioning signal (S610); specifying an emission source of the positioning signal (S612); obtaining, when the emission source of the positioning signal is outdoors, a navigation message included in the positioning signal (S622); executing a process for calculating the position based on the signal (S624); obtaining, when the emission source of the positioning signal is indoors, message data from the positioning signal (S630); obtaining coordinate values from the data (S632); and displaying positional information based on the coordinate values (S650).

    摘要: A navigation signal transmitting apparatus and a location information providing apparatus are provided for reducing time of positioning with a positioning signal from an indoor positioning transmitter. When an information providing server recognizes a transmitter ID of a transmitter from a mobile phone, the server makes reference refers to database associated with the transmitter ID, and reads SVG map information associated with the ID (including information for displaying a map and information of a correspondence relation between the transmitter ID and the location of the transmitter on the map). When the server transmits data of the SVG map information to a base station, the base station wirelessly emits the data of the SVG map information. When the mobile phone detects arrival of the data, the mobile phone can obtain the location of the transmitter from the data in accordance with a browsing operation of a user of the phone.

    摘要: Provided is a navigation signal transmitter capable of ensuring reduction in frequency deviation of a terrestrially transmitted navigation signal at low cost. The navigation signal transmitter is operable to receive a transmission wave, generate a synchronization pulse in synchronization with a predetermined data frame, generate an internal clock fundamental oscillation by a reference signal synchronizing section (550) using the synchronization pulse as a reference signal, generate an IMES signal based on the internal clock fundamental oscillation, and transmit the IMES signal. The reference signal synchronizing section (550) comprises a counter circuit (551), a comparator (553), a low-pass control filter (554), a D/A converter (555) and a voltage controlled oscillator (556). The reference signal synchronizing section (550) is configured to, when a magnitude relationship between the number of clock pulses generated in the voltage controlled oscillator (556) using the synchronization pulse as the reference signal and a reference value falls within a predetermined value and continues a predetermined number of times in one direction, adjust a level of control voltage of the voltage controlled oscillator (556).
