EVK-M10QSAM - User guide
9.3 Navigation update rate
The
CFG-RATE-MEAS
configuration key that is shown in
the navigation update rate. The navigation update rate value is defined in ms, where 100 ms
corresponds to 10 Hz. The default update rate is 1000 ms which corresponds to 1 Hz. The default
1 Hz update rate is a good tradeoff between position accuracy and power consumption. Certain
applications require faster update rates for high performance but this will increase the receiver
power consumption.
Increase the communication baud rate and reduce the number of messages that are enabled
when high navigation update rates are used. The maximum baud rate of 921600 or 460800 baud
rate should be sufficient for most use cases.

9.4 Power modes
EVK-M10QSAM supports the following power modes and can be configured with the
CFG-PM-
OPERATEMODE
configuration key.
•
Continuous mode (FULL):
This is the full power mode and the default mode of the receiver. No
power save mode is active in this mode.
•
On/Off mode (PSMOO):
This is a power save mode for reducing the power consumption of
the receiver. In this mode, the receiver is configured to be periodically turned on or off for
applications that require less frequent position updates. Typically used for update periods
longer than 10 seconds.
•
Cyclic tracking mode (PSMCT):
This is also a power save mode for applications that require
more frequent position updates. Typically used for short update periods in the range of 0.5 to
10 seconds. In this mode, the receiver does not shut down completely between position fixes,
but uses low-power tracking instead.
BeiDou B1C is not supported in power save mode (PSM). Some PSM states clear the
RAM memory. Store receiver configuration in BBR to maintain the settings. In addition, it is
recommended to disable SBAS because the receiver is unable to download or process any SBAS
data in PSM.
