How Can Fleet Managers Improve Their GPS Systems?


Managing a fleet of vehicles such as trucks may come with its own set of struggles. Alongside driver safety, fuel costs, maintenance, and vehicle usage are on-time deliveries as one of the more crucial factors that worry most fleet managers. Although GPS trackers are enabling efficiencies on the road, the technology is still not safe from tampering.

GPS jammers can create problems for trackers as the device jams signals, rendering information from the system useless. A jamming simulator can prevent such a hazardous situation from jeopardizing your fleet.

The Need for an Anti-Jam Test

GPS systems are very useful for fleet managers because they help to optimize the drivers’ route. It serves as a big help because the system can redirect drivers away from road constructions, detours, and traffic jams. With an optimal performance from the GPS, your drivers can arrive on time and make their deliveries.

As GPS tracking technologies emerge, GPS jamming devices also rise. So much so that people can easily buy online, even though these devices are illegal to sell and use in the US. Jammers block or interfere with GPS systems. This emphasizes the need for jamming simulators. So as not to disrupt work operations, testing your GPS tracking devices and the threats they may face with a GPS jammer can help you negate these problems.

The Speed and Time Measurement

The speed accuracy of GPS, which depends on many factors, with a 95 percent probability. The global average user range rate error (URRE) is ≤0.006 m/sec over any 3-second interval. Certain elements, like atmospheric conditions, satellite geometry, signal blockage, and receiver design quality, affect a receiver’s speed accuracy.

Through the GPS signal in space, the time transfer accuracy, 95 percent of the time, is the performance standard that assumes the usage of a specialized time transfer receiver at a fixed location.

The Various Augmentation Systems for GPS

As a civilian user, you can get improved GPS accuracy with augmentation systems. These systems can enhance the precision, availability, integrity, and other factors related to positioning, timing, and navigation.

Some examples of augmentation systems are:

  • Wide Area Augmentation System (WAAS) – It’s a regional space-based augmentation system, (SBAS) which the Federal Aviation Administration (FAA) operates. WAAS supports aircraft navigation across North America.
  • Continuously Operating Reference Stations (CORS) – The National Oceanic and Atmospheric Administration (NOAA) manages the U.S. CORS network. It stacks and sorts GPS data for accurate positioning linked with the National Spatial Reference System.
  • Nationwide Differential GPS System (NDGPS) – This ground-based augmentation system offers improved accuracy and integrity of GPS info to users on U.S. waterways.

The Need for Jamming Simulator

Our Anti-Jam Testing system can identify the efficiency of GPS services and prevent potential risks. This interference generation system can test the support of the anti-jam performance of your GPS receivers.

It allows you to indicate jamming levels and signal transmission characteristics for narrowband and broadband jammers. You can operate it in standalone mode. You can also use it as a supplement to a CAST simulator.
