摘要:
An apparatus that can transmit a signal enabling higher accuracy of calculating positional information is provided. A transmitting apparatus 200 transmitting a positioning signal includes an oven controller crystal oscillator (OCXO) 210 having a thermostatic oven that keeps the temperature of a quartz resonator constant and oscillates such that variation in output frequency caused by the ambient temperature change is minimized, a voltage controlled oscillator (VCO) 220 outputting a signal modulated in accordance with the signal from OCXO 210, multipliers 240 and 260, a code generator 230 outputting code patterns for respectively identifying each of artificial satellites on which the transmitting apparatus 200 is mounted to multiplier 240, a memory 250 storing a navigation message, a transmitting portion 280, and an antenna 290.
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.
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).
