Alwayslocate™ Mode - Quectel L76 Hardware Design

NOTE
1. When the modules enter GLP mode, the 1PPS and the SBAS functions are disabled.
2. In highly dynamic scenarios, the positioning accuracy of the modules in GLP mode is slightly
reduced.
3.3.6. AlwaysLocate™ Mode
AlwaysLocate™ is an intelligent power saving mode. It contains AlwaysLocate™ backup mode and
AlwaysLocate™ standby mode.
AlwaysLocate™ standby mode allows the modules to switch automatically between Continuous mode
and Standby mode. According to the environmental and motion conditions, the modules can adaptively
adjust the Continuous time and Standby time to achieve the balance between positioning accuracy and
power consumption. Sending software command and the modules returning a corresponding command
means the modules access AlwaysLocate™ standby mode successfully. It will benefit power saving in
this mode. Sending software command in any time will make the modules back to Continuous mode.
AlwaysLocate™ backup mode is like AlwaysLocate™ standby mode. The difference is that
AlwaysLocate™ backup mode switches automatically between Continuous mode and Backup mode.
Sending software command makes the modules enter AlwaysLocate™ backup mode. Pulling WAKEUP
high and immediately sending software command will make the modules enter Continuous mode.
For more information about these commands, see document [1].
The position accuracy in AlwaysLocate™ mode will be degraded, especially in highly dynamic scenarios.
The following figure shows the rough consumption in different scenes.
