Japan Aerospace Exploration Agency (JAXA)
The Japan Aerospace Exploration Agency (JAXA) confirmed that the quality and reliability for positioning signals (L1-C/A and L2C*1) of the First Quasi-Zenith Satellite (QZS) "MICHIBIKI" satisfied the QZS system user interface specifications (IS-QZSS) through technological verification, thus lifting the alert flag*2 for the L1-C/A and L2C positioning signals on June 22.
We will remove the alert flag for the remaining positioning signals (L5 and L1C*3) after their compliance with the IS-QZSS is verified.
As the alert flags were dismissed, a GPS receiver corresponding to the MICHIBIKI will be able to use MICHIBIKI's positioning signals for its calculations.
JAXA is engaging in promotional activities to develop a commercial GPS receiver that corresponds to the MICHIBIKI including a program called "supporting system for corresponding a commercial GPS receiver with the QZSS (QZ-support.)" (Please refer to the attachment.)
We expect to expand the environment where people can enjoy MICHIBIKI's effectiveness through lifting the alert flags and popularization of receivers corresponding to the MICHIBIKI.
