Stationary Assets
Whereas a personal automobile normally moves on a daily basis, other assets are
expected to remain stationary. When a stationary asset does move, it truly is an
extraordinary event requiring immediate action. Under normal stationary
conditions, perhaps all that is required is a periodic heartbeat from the unit letting
the server application know that the locator is still alive and functioning.
Using the Scheduled Report Mode, Report Delay Flag and Motion Report Flag,
the unit can closely monitor and report upon initial movement while providing a
regularly scheduled heart beat. Expected battery life of four AA alkaline
batteries, assuming default configuration settings, except those depicted in Table
16, would be approximately 9-10 months even if the asset moved once a week for
an hour or so.
Setting Point Counterpoint
Scheduled Report Mode set
to either “1=Daily” or
“2=Weekly”.
Provides a regularly
scheduled
STATUS_MESSAGE
letting the server
application that device is
operational and give a
battery level indication.
Does not cause a new
position fix to be computed
even if there has been
motion since the last logged
position, but in a stationary
application, this should be
of little consequence.
Report Delay Flag set
“2=Tx Motion-related &
Exceptions”
Saves power and
communication costs by not
transmitting any
STATUS_MESSAGE
triggered by expiration of
DELAY Timeout, T4.
If want only Schedule
Report and Motion Report
Triggered messages
transmitted, set Report
Delay Flag to “
1=Tx
Exception Reports only
”
.
Motion Report Flag set
“
1=Report Motion in IDLE
(before attempting new GPS
fix)”
Sends notification to server
application immediately
upon sensing of initial
motion in the IDLE State.
Then goes and does a
position fix.
May not be worth the extra
data message in some
applications.
