Experts at the German Aerospace Center (DLR) are analyzing signals from Japan's first quasi-zenith satellite, Michibiki, which began transmissions (including the first transmission from space of the new civil signal, L1C) on October 26, according to the Japan Aerospace Exploration Agency (JAXA).

The accompanying figures show the spectral flux density and a scatter plot of the QZS-1 L1 signals that were recorded with DLR´s 30-meter high-gain antenna at Weilheim last week. The L1 signal contains two GPS-compatible L1C and L1 C/A components, and the L1-SAIF which is a signal compatible with GPS satellite-based augmentation systems.

JAXA’s initial functional verification of Michibiki is expected to last about three months.
