How A GPS Tracker Works

GPS tracking devices can be used to track people, vehicles and other assets, anywhere on Earth. Currently, there are 27 satellites orbiting the earth, 24 are operational, the other three will become operational if one of the satellites happen to fail. At any given time there are at least three satellites that are visible in the sky from a location. These satellites then triangulate on the position of the GPS tracking device. By continuing to triangulate the coordinates at regular intervals, the satellites can determine the speed of an object, the distance traveled and how long it has been stationary.
There are two main types of GPS tracking systems currently on the market today. They are classified as Passive and Active/Live (real-time) Tracking.
KJB Security's passive GPS tracking devices include the I Trail historical tracker.
US Fleet Tracking's active GPS tracking systems include the PT-X5 real-time GPS tracker and the OBD-X5 tracker.
Not all GPS tracking devices are created equal. When considering the purchase of a GPS tracking unit, comparisons should be made based on accuracy, sensitivity, frequency of sampling points, power sources, reliability, and the software that translates the data into an understandable, easy-to-use format.

GPS Tracking Accuracy

All Us Fleet Tracking GPS tracking devices, whether they are active or passive, provide locations that are accurate within 2.5 meters (or roughly 7 feet).

GPS Tracking Sensitivity

Since GPS Tracking for many users is covert in nature, the tracking device needs to be manufactured in a way that maximizes GPS reception. Most traditional GPS devices need a clear view of the sky and will lose GPS reception if placed in some concealed positions. The Us Fleet Tracking line of GPS tracking devices have been designed with that concern in mind. They are sensitive enough that they can be hidden in covert locations while retaining and maintaing good reception.

GPS Tracking Frequency of Sampling Points

The KJB Security passive I Trail GPS Tracking device capture and store GPS signals including time, position, and speed once every second. Competing products capture data once every five (5) to ten (10) seconds per sampling. The second-by-second data represents a better flow of information that can be used to generate greater and more detailed reports.

GPS Tracking Power Sources

Since the majority of GPS tracking customers prefer portability from their units, it is critical for the devices to be able to manage power efficiently. All of Us Fleet Tracking's devices provide a minimum of 20 hours of wheels in motion tracking. Internal sensors put the device into sleep mode when the vehicle is not in motion, which helps in extending battery life. Users of the device can expect to receive days or even weeks of tracking ability. Results will vary based on the number of hours in motion per day.

GPS Tracking Reliability

All Us Fleet Tracking products go through extensive pre-development research and testing to ensure that our customers are purchasing products that are at the forefront of GPS tracking technology. These strict requirements have helped in establishing Us Fleet Tracking as an industry leader, making our GPS tracking solutions the systems of choice, regardless of customer type.

GPS Tracking Software

Us Fleet Tracking's vehicle tracking software offers three ways to view and evaluate tracking data in a user-friendly package that will appeal to both novices and advanced computer users.

• Digital street map: Gives a historical, moment-by-moment replay. Shows when and where the vehicle traveled. Screen shows animated tools, including speedometer, clock with second hand and compass.
• Google Earth satellite map: Accurately displays the driving path and stops on a satellite image.
• Text activity report: Gives a daily summary, divides driving activity into segments with detailed descriptions including starting address, departure time, time en route, arrival time, miles traveled and how long the vehicle stayed at each location.

The significance of second by second data is critical in providing a comprehensive, fluid replay of any and all historical tracking data. Any device providing less than second by second recording falls short of these expectations. As an example, Kjb Security Product's Passive GPS Tracking devices are able to record 3,600 positions per driving hour whereas competing devices recording every 5 seconds, which only provides 720 positions per driving hour.
