200 – PowerManagement

This command sets the power mode to Full Power, Adaptive Trickle Power,

or Push-to-Fix mode. Figure 29 contains the values for the following

example to set the receiver to Adaptive Trickle Power mode:

$PLSC,200,2,200,3000,300000,30000*0D

Mode

See Figure 30

OnTime

200

(200 – 900)

Must be a multiple of 100 (if not, it is

rounded up to the nearest multiple of 100).

Set this to 0 when Mode = 3.

LP Interval

3000

(1000 – 10000)

Must be an integer value

≥1000 and

≤10000. Set this to 0 when Mode = 3.

MaxAcqTime

300000

(

≥1000)

When Adaptive Trickle Power is enabled,

this is the maximum allowable time from

the start of a power cycle to the time a valid

position fix is obtained. If no fix is obtained

in this time, the receiver is deactivated

for up to MaxOffTime, and a hot start is

commanded when the receiver reactivates.

The integer must be in multiples of

1000ms. There is no upper limit.

MaxOffTime

30000

(1000 –

1800000)

The longest period (in mS) for which

the receiver deavtivates due to the

MaxAcqTime timeout. The actual

deactivated period may be less if the

user-specified duty cycle (OnTime /

LpInterval) can be maintained.

PushToFixPeriod

(10 – 7200)

sec

The receiver automatically awakens every

Push-to-Fix period to obtain a position fix,

collect ephemeris (if needed), and calibrate

the real-time clock (RTC) (if needed).

The receiver outputs a response to this command. Figure 31

contains the response for the above command:
