QZSS Decoded Message Blocks
QZSNav
Number:
4095
"OnChange"
interval: block generated each time a new navigation data set is
received from a QZSS satellite
The
block contains the decoded navigation data for one QZSS satellite. The data is
decoded from the navigation message transmitted by the L1C/A or L1C/B signal. Refer to the
QZSS ICD for further details.
