9.5 Receiver Start Operation
The GNSS+DR receiver backs up the last updated position, the direction and the DR parameters. At the next
power on, the GNSS+DR receiver starts the positioning in DR only mode by using the backup data. After that,
when the direction calculated by DR is coincident with the GNSS direction, the position mode changes to
DR/GNSS mixed mode. The GNSS+DR receiver outputs the positioning result by DR only until the position
mode changes to the DR/GNSS mixed mode.
