Reduced Messaging
Reduced Messaging Mode lowers the cost associated with transmitting messages over Globalstar’s
satellite network by sending messages at a minimal message interval when the asset is in a defined area
and transmits at a higher message interval when the asset is changing locations. These message
intervals are set as part of the configuration process based on the concept that repeated reporting
information of the same location, when an asset has not moved from its defined area, is redundant and
doesn’t provide addition usable information about its current location.
By comparing current and prior position information, the SmartOne determines if its location is changing.
The definable area in which the device should remain in Reduced Messaging Mode is called the Change
of Location Area and it is a square. When the SmartOne goes outside of the square, its location is
considered to be changing or relocating.
Usage Example: A fleet operator owns 1,000 trailers. When the trailer(s) are sitting at a depot they
want a location message once a day. They also want a message notification within 1 hour when a
trailer has left a depot. Lastly, they want a location message every 3 hours when a trailer is moving
between depots. Based on this requirement, the fleet operator will need to set the Change of Location
Area (size of the depots where the trailers will visit), the message interval while the trailers are inside
the Change of Location Area (1 per day), the interval at which the SmartOne will check its location
while in a State of Vibration and inside the Change of Location Area(1 per hour), set the number of
messages when the trailer leaves the Change of Location Area (1 Change of Location Area Alert
Message) and the message interval while the trailers are in transit between depots (every 3 hours).
Theft Recovery
When the SmartOne is configured to operate in the Theft Recovery Mode, it differentiates between
authorized and unauthorized movement of an asset. While the power to the SmartOne is turned off, all
movement of the asset is considered authorized. When power is turned on, the SmartOne obtains a
position from GPS satellites. The position is used to set the center of the defined Change of Location
Area in Theft Recovery Mode. While in the Change of Location Area, the SmartOne obtains position fixes
at an interval set during configuration. As long as the SmartOne remains within the Change of Location
Area all movement is considered to be authorized.
Once the SmartOne’s position is outside of the Change of Location Area, it alerts the SmartOne to an
unauthorized movement and immediately sends a location message (Change of Location Alert Message).
The SmartOne continues to send location messages at a message interval set during the configuration
process until the power is turned off or the battery is dead.
Usage Example: A construction company is working on a job site for 1 year and wants to ensure
that their generators and other heavy equipment on site aren’t stolen. The company wants to check
the location of their equipment 12 times a day, every 2 hours, to confirm the asset hasn’t been stolen,
but only wants a transmitted location message once per day. Based on this requirement, the
construction company will need to set the Change of Location Area (size of the job site), the message
interval while inside the Change of Location Area (1 per day), the interval at which the SmartOne will
check its location while in a State of Vibration and within the Change of Location Area (every 2 hours)
and the message interval if the asset is outside the Change of Location Area (stolen).
