Measuring Power Consumption
6.1. Power Consumption at Different Stages
Module power consumption is measured in four stages: acquisition and tracking (including almanac
update), tracking (almanac update is over), upon entering ALP mode and Backup mode.
Acquisition and tracking (including almanac update): 0 s to 12.5 min
Tracking (almanac update is over): > 12.5 min

Figure 11: Power Consumption at Different Stages
The EVB works normally. After entering the tracking mode, the module enters the ALP mode when the
$PAIR732,1*21
command is sent. Then, the power consumption of the ALP mode can be measured.
Record the average value after the power consumption of the ALP mode is stable. For more information,
