Michibiki 7

QZSS (Quasi Zenith Satellite System) is a Japanese satellite navigation system operating from inclined, elliptical geosynchronous orbits to achieve optimal high-elevation visibility in urban canyons and mountainous areas, as well as from geostationary orbits. The navigation system objective is to broadcast GPS-interoperable and augmentation signals as well as original Japanese (QZSS) signals from a seven-spacecraft constellation. Michibiki 7 also carries a Space Situational Awareness payload from the US Space Force developed by the MIT Lincoln Laboratory known as the Situational Awareness Camera Hosted Instrument (SÃCHI).
