15.3. SELF MANAGED POWER SAVING MODES

Multi Spider module has several self-managed power saving modes tailored for different use cases.

These modes provide several levels of power saving with degradation level of position accuracy.

Initial operation in Full Power state is a prerequisite for accumulation of satellite data determining

location, fine time and calibration of reference clocks.

15.3.1. ADAPTIVE TRICKLE POWER (ATP™)

ATP™ is best suited for applications that require navigation solutions at a fixed rate as well as

low power consumption and an ability to track weak signals.

This power saving mode provides the most accurate position among self-managed modes.

In this mode module is intelligently cycled between Full Power state, CPU Only state consuming

15mA and Standby state consuming ≤ 0.1mA, therefore optimizing current profile for low

power operation.

ATP™ period that equals navigation solution update can be 1 second to 10 seconds.

On-time including Full Power Tracking and CPU Only states can be 200ms to 900ms.

15.3.2. PUSH TO FIX (PTF™)

PTF™ is best suited for applications that require infrequent navigation solutions.

In this mode ORG4572 module is mostly in Hibernate state, drawing ≤ 54µA of current, waking

up for satellite data refresh in fixed periods of time.

PTF™ period can be anywhere between 10 seconds and 2 hours.

Host can initiate an instant position report by toggle the ON_OFF pad to wake up the module.

During fix trial module will stay in Full Power state until good position solution is estimated or

pre-configured timeout for it has expired.
