Avg speed

Average speed. The average speed during a device’s report interval, which is calculated using the distance traveled (beginning and ending odometer values) and time (update period).



Represents more than one vehicle in a similar location on a map.



Diagnostic data is an additional feature. Diagnostic data varies by vehicle make/model/year.


GPS drift refers to the magnitude of inaccuracy of a device’s positional data (e.g., the number of meters within Circular Error Probability).



Gravitational force. 1 G is equal to the force of gravity at the Earth’s surface, which is 9.8 meters per second.

Google Places

Includes place information on a variety of categories, such as: establishments, prominent points of interest, geographic locations, and more.


Used to organize your vehicles using classifications that make sense to your business.


Inst speed

Instantaneous speed. The last speed value sampled during a device’s report interval.


Max speed

Maximum speed. The highest speed value sampled during a device’s report interval.



Normalization allows you to more accurately compare data among multiple vehicles (drivers), typically related to event violations.


Out of range

A message that may indicate the vehicle’s GPS device is not reporting data.

Overlapping trip

A trip (engine on to engine off) that occurs during an overnight/midnight threshold.


Posted speed

The maximum lawful vehicle speed (in multiples of 5 mph) for a particular location as displayed on a regulatory sign.


Power Take-Off. A device used on a vehicle to provide power to an attachment or separate system (hydraulic or mechanical).



Total vehicle hours.


Snap to roads

The snap to roads option allows you to alter the representation of the trails. Vehicle locations are typically provided every two minutes.

Speed limit disclaimer

Many speed limits are 5-10 MPH different in either direction, and the data is not guaranteed.

Speed sample

Each vehicle is typically on a 2-minute report interval. During that time, the device is sampling speeds usually at 4 times per second.

Stop note

Allows drivers to add information about various stops (e.g., “Customer was not home for delivery.”).

Sustained speed

Occurs when two or more consecutive instantaneous speed points are above the speeding threshold.



When setting up an alert with time conditions, the alert uses the timezone preference set in your user profile.

Tracking data

In addition to ignition status, data is tracked for the following: Stopped and/or over idling threshold, out of range, PTO engaged, vehicle speed (max and average speeds between updates) GPS location (lat/long, reverse geo-coded address, and/or landmark if applicable), direction (heading), odometer, and more.


Defined as the period between ignition “on” and ignition “off.”

Trip summarization

A 24-hour period (midnight to midnight) based on the timezone setting of the master user on the account.

Trip summary identifiers

System identifers that summarize a trip based on Days Utilized, Trips, Idle Time, Distance, and Engine Hours.
