15. POWER MANAGEMENT

15.1. POWER STATES

15.1.1. FULL POWER ACQUISITION

ORG4572 module stays in Full Power Acquisition state until a reliable position solution is made.

Switching to GPS-only mode turns off GLONASS RF block lowering power consumption.

15.1.2. FULL POWER TRACKING

Full Power Tracking state is entered after a reliable position solution is achieved.

During this state the processing is less intense compared to Full Power Acquisition, therefore

power consumption is lower.

Full Power Tracking state with navigation update rate at 5Hz consumes more power compared

to default 1Hz navigation.

15.1.3. CPU ONLY

CPU Only is the transitional state of ATP™ power saving mode when the RF and DSP sections are

partially powered off. This state is entered when the satellites measurements have been

acquired, but navigation solution still needs to be computed.

15.1.4. STANDBY

Standby is the transitional state of ATP™ power saving mode when RF and DSP sections are

completely powered off and baseband clock is stopped.

15.1.5. HIBERNATE

ORG4572 module boots into Hibernate state after power supply applied.

During this state RF, DSP and baseband sections are completely powered off leaving only RTC

and Battery-Backed RAM running.

ORG4572 will perform Hot Start if stayed in Hibernate state less than 4 hours from last valid

position solution.

15.2. BASIC POWER SAVING MODE

Basic power saving mode is elaborating host in straightforward way for controlling transfers between

Full Power and Hibernate states.

Current profile of this mode has no hidden cycles of satellite data refresh.

Host may condition transfers by tracking duration, accuracy, satellites in-view or other parameters.
