|20140016722||NAVIGATION SIGNAL TRANSMITTER AND METHOD FOR GENERATING NAVIGATION SIGNAL - 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 (||01-16-2014|
|20130279543||NAVIGATION SIGNAL TRANSMITTING APPARATUS, LOCATION INFORMATION PROVIDING APPARATUS, METHOD FOR TRANSMITTING NAVIGATION SIGNAL, AND METHOD FOR PROVIDING LOCATION INFORMATION - 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.||10-24-2013|
|20130127660||NAVIGATION SIGNAL TRANSMITTING APPARATUS, NAVIGATION SIGNAL TRANSMISSION METHOD AND POSITIONAL INFORMATION PROVIDING APPARATUS - A navigation signal transmitting apparatus, provided on ground, for transmitting a navigation signal to a receiver capable of positioning by receiving a spread spectrum satellite positioning signal from a satellite has first and second transmission antennas; a message generating unit that generates a message signal of positional information included in the navigation signal, and a modulating unit that modulates the message signal by a modulation process including spectrum spreading, based on spread codes of the same sequence as the satellite positioning signal allotted in advance to the navigation signal transmitting apparatus, for generating first and second navigation signals. The modulating unit executes the modulating process using either one of the first and second navigation signals as an object of demodulation at each time of reception by the receiver.||05-23-2013|
|20110050493||POSITION INFORMATION PROVIDING SYSTEM INDOOR TRANSMITTER AND METHOD FOR PROVIDING POSITION INFORMATION - 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.||03-03-2011|
|20100290504||POSITION INFORMATION PROVIDING SYSTEM INDOOR TRANSMITTER AND METHOD FOR PROVIDING POSITION INFORMATION - It is intended to provide position information in a location where it is difficult for radio waves to penetrate. An indoor transmitter is capable of programmably changing a format of a transmitter signal. A process to be performed by a position information providing apparatus comprises the step (S||11-18-2010|
|20090115661||POSITIONAL INFORMATION PROVIDING SYSTEM, POSITIONAL INFORMATION PROVIDING APPARATUS AND TRANSMITTER - 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 (S||05-07-2009|
|20080231513||SYSTEM FOR TRANSMITTING POSITIONING SIGNAL - A system for transmitting time-synchronized signals for positioning is provided. The system for transmitting positioning signals includes a transmitting apparatus mounted on artificial satellite, a repeater mounted on an artificial satellite, and a repeater mounted on an artificial satellite. Positional relation among artificial satellites is specified beforehand. Transmitting apparatus transmits a signal generated by encoding using a code identifying itself. Repeater receives a signal from the transmitting apparatus and transmits the signal. Repeater receives a signal from the transmitting apparatus and transmits the signal. The signals transmitted from the transmitting apparatus and repeaters and are received by receiving apparatuses and having the function of receiving the signals.||09-25-2008|
