Quasi-Zenith Satellite "MICHIBIKI" is available now from the position signal. Signals are available to complement the existing GPS signals, it is possible to measure more accurate positioning.
Japan Aerospace Exploration Agency (JAXA) at 9:00 am on June 22, QZSS "MICHIBIKI" was made available from the position signal. If the handset is activated, enabling a more accurate measurement of the position to complement the existing GPS signals.
Interoperable with GPS and the current "L1-C / A" (1.5GHz) and "L2C" (1.2GHz) will release a warning flag because it meets the quality and reliability specifications are available for the current position.
For guidance, the start time approximate estimate of Fujitsu General is responsible for the SI and the development of positioning system by the NEC. Target specifications are needed to understand the ± 2.6 m distance for guidance, has been achieved in this case 100%. Mechanism of GPS, position accuracy can lead to an accurate distance to the satellite. GPS error of the specification is ± 7.6 meters, that there are several variations of the satellite generation.
Although guidance signals a predefined, and car navigation systems in general need to be addressed to the recipient. That some will be available in a firmware update. More to consider concrete products by Sony, Epson has been the product will be compatible with the future.
MICHIBIKI was launched in September last year, above about (quasi-zenith) and sends a signal to complement the position of the GPS signal which is characterized by that will be available in the shade of buildings or mountainous areas, now leads because it operates in one unit, looks straight from the day in Tokyo, about eight hours. Strategic Space Development Headquarters this government has been considering since the launch of Unit 2, operate in some system reports a total of four aircraft, which reportedly planned to be available 24 hours.
