摘要:
Provided is a position information providing system which can reduce a time required for acquiring position information. An indoor transmitter (200-1) 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 (200-1) includes an EEPROM (243) which stores therein position data for identifying an installation location thereof, an FPGA (245) operable to generate a second positioning signal including the position data as a spread spectrum signal, and a transmitting section (251 to 258) 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.

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 each of which achieves reduced time of positioning with a positioning signal from an indoor positioning transmitter. When an information providing server (1230) recognizes a transmitter ID of a transmitter (1210) from a mobile phone (1200), the information providing server (1230) makes reference 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 information providing server (1230) transmits data of the SVG map information to a base station (1240), the base station (1240) wirelessly emits the data of the SVG map information. When the mobile phone (1200) detects arrival of the data, the mobile phone (1200) can obtain the location of the transmitter (1210) from the data in accordance with a browsing operation of a user of the mobile phone (1200).
摘要:
An information management system (10) includes: a mobile communication terminal (100) capable of obtaining location information; and a medical institution (130) provided with a regional medical data bank system (120) and a transmitter (131). The mobile communication terminal (100) transmits a space-time tag and a terminal ID to the regional medical data bank system (120). The space-time tag is constituted of time information and location information. A space-time ID information processing unit (121) of the regional medical data bank system (120) generates a space-time ID in a folder for each user based on a plurality of space-time tags and stores it in space-time ID information DB (122). A terminal device (133) of the medical institution (130) transmits the location information of the mobile communication terminal (100) and the time information to the regional medical data bank system (120). A verification processing unit (124) verifies information from the mobile communication terminal (100) against information from a utilization terminal (141) and transmits the information to the utilization terminal (141) when a request for transmission of the information is valid.
