Almanac is a set of data that depicts the trajectory of each satellite. It is used to calculate the satellite's approximate position. Almanac for QZSS are available at this site. The data format is YUMA.
Only the definition of “Health” is not identical with the IS-GPS-200E and IS-QZSS-JAXA.
In the QZSS Almanac, health of the satellites are written in the form of 5bit in decimal as defined in the IS-QZSS. The 5-bit health is the SV health of all PNT signals including L1C/A, L1C, L2C and L5. The "0" is placed when the signal is available, "1" when not available. Refer the IS-QZSS-PNT 18.104.22.168.2 for more information.
