Usage Example: A Company is required to report the GPS locations
of their hazardous chemical containers twice a day. Based on
this requirement the Company has 2 options: set a message interval of
every 12 hours, the 12 hour internal begins when the device is
powered up or configure message times of day 12:00 noon and 12:00
midnight.
Reduced Messaging
Reduced Messaging Mode reduces the cost associated with transmitting
messages over Globalstar’s network by sending messages at a minimal
message interval when the asset is in a defined area and transmitting 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 satellite signals. 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.
