| 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 |
