GPS Simulators: The Basic Principles Behind This Technology

As an organization developing devices or equipment heavily reliant on satellite signals, one of the first things you need to prioritize is ensuring they can perform the demanding tasks you intend for them. Without the proper GPS tools though, you don’t have the guarantee that they can satisfy the real-world needs you designed them for.

The good news is, much thanks to Global Positioning System simulating devices, such as the multi-element GPS simulator, you can test your devices’ suitability and functioning before launching them out in the market. Knowing the general principles behind its use will help you recognize its value and importance in your organization’s operations.

Accurately tracking satellites: The cornerstone of all successful GPS-enabled devices

The ability to track and pinpoint satellite signals accurately is key to having a fully functional, successful GPS-enabled device. This said, you need to make sure your device has this power before you give the public access to it.

Because live-sky testing comes with so many possible variables, it doesn’t offer you a feasible way to study your device’s capabilities and functionalities. From satellite clock and orbit errors to navigation data and atmospheric errors, the list goes on and on. This is why laboratory testing with GPS simulators is crucial to any device pre-launch testing.

Controlled testing through GNSS simulating technology

The basic principle behind the use of GPS simulators is to test navigation systems within a controlled and secure laboratory. With these satellite signal-simulating tools, you have complete control over the factors that are otherwise unknown with live testing.

For instance, you can test under controlled constellation signals and environmental conditions. You also don’t have to worry about unintended or unintentional interference, as well as unnecessary signal effects. And of course, testing is repeatable.

These are just some of the conditions that you can expect through controlled testing using GPS simulators. However, they should be enough to make you acknowledge that they are indeed a must when it comes to designing GPS-enabled devices.
