Operation modes
There are three operation modes in the positioning, and they can be specified using the @GSOP command.
These operation modes can be switched during operation.
Normal
In this mode, all the GPS-related circuits are activated, and the positioning operation is performed continuously.
In this mode, the GPS circuits and positioning processing are operating so the power consumption is the
highest but the performance is also the highest.
The Sleep time can be specified only when the Normal mode has been selected. Operation transfers to the
Sleep mode only for the specified time with each positioning cycle, and the positioning operation is performed
continuously for the remaining time of the positioning cycle.
Low Power
In this mode, the positioning operation is performed at a low level of power consumption. Once the satellites
are picked up and positioning starts, some of the GPS circuits are set to OFF, and operation is performed
intermittently at a low level of power consumption. If the positioning has failed or the number of satellites has
decreased, some of the GPS circuits are set to ON, and the positioning operation is performed continuously.
Normal mode
The RYS8830 works continuously with all GPS circuits activated and outputs NMEA sentences with the specified
period by @GSOP as shown in Fig. NMEA sentence is output immediately after the first fix, then NMEA sentence
is output with the specified period again from that point.
