people with ground receivers to pinpoint their geographic location.
GPS reading – The longitude, latitude, time, and date information
obtained from processing the signals from the GPS satellites.
I
In Motion – The unit is considered to be In Motion when there is a State
of Vibration – and – when a comparison of a new GPS reading to a
previous GPS reading indicates the tracker has changed location by at
least a specified minimum distance. The specified minimum time and the
specified minimum distance are both configuration parameters.
Inaccurate GPS reading – The longitude and latitude information obtained
from processing the signals from the GPS satellites when a tracker can
not observe an adequate number of satellites; the GPS signals were
jammed by electronic interference; the GPS signals were reflected from
objects creating multi-path conditions; or weather conditions distorted
the GPS signals. An inaccurate GPS reading may have longitude and
latitude errors of a mile or more.
Input – A digital channel in the device that allows the detection of
switch stage changes. The inputs are dry contact inputs, ON/OFF.
Level of Sensitivity for Vibration Sensor – a configurable parameter
that sets the number of pulses per minute that a vibration sensor must
detect to be considered sensing vibration.
M
Message – A collection of information that is transmitted in a group
over the satellite network.
Message Interval – The amount of time specified by the user between
Location Messages. The SMARTONE transmits a Location Message once the
Message Interval has elapsed. The internal clock on the device is reset
to the interval time after each transmission. The SMARTONE is in low
power consumption Mode during the interval to preserve battery life.
Message Time(s) of Day – The specific time of day in military format for
the SMARTONE to transmit Location Messages. . The SMARTONE is in low
power consumption Mode between the specific times of day to preserve
battery life.
Message Transmission – The process of sending a message over the
satellite network. The process includes sending a message multiple
times to improve the transmission success rate.
N
Number of message repeats – The number of times a message is send in a
message transmission with the same UMN. The number of message repeats
