The QZSS is a Japanese satellite navigation system that augments the U.S. GPS in the Asia-Pacific region. QZS-7 will be launched on H3 flight no. 9 on an H3 Model 22 vehicle. QZS-7 would have completed the 7-satellite configuration of the QZSS but QZS-6 was lost in a Dec 2025 launch failure. In addition to the main payload, it carries a Situational Awareness Camera Hosted Instrument (SACHI), a Space Situational Awareness (SSA) payload developed by MIT Lincoln Laboratory for the U.S. Space Force. A similar camera piggybacked on the QZS-5 satellite as well.
