Multi-Antenna GNSS Simulation for Unmanned Aerial Vehicles (UAVs)

Problem We Solve

When testing unmanned aerial vehicles (UAVs) such as drones, GNSSGlobal navigation satellite system (GNSS): A general term describing any satellite constellation that provides positioning, navigation, and timing (PNT) services on a global or regional basis. See also simulators can generate a signal to represent the UAVUnmanned Aerial Vehicle. Remotely piloted aircraft commonly referred to as a drone. See also. But how those vehicles interact with others and perform in GPSGlobal Positioning System is a navigation satellite system. See also and GNSS-denied environments can make all the difference in their performance. And many drone applications rely on multiple antennas for positioning and heading.

Why it is Important

In case of a spoofing attack, embedded sensors might receive compromised data to make the unmanned vehicle drift from its initial trajectory. By testing unmanned vehicles before sending them on the field, you will be able to configure them properly to react to jamming and spoofing attacks.

Thorough test plans should account for as many scenarios as possible to ensure the safety of the end product. A GPS/GNSS simulator makes it possible to simulate the actual GPS signal required by the vehicle, and in cases described above, the ability to simulate multiple RF signals for multi-antenna UAVs.

How We Solve it

• Our Skydel Software running on a GSG-8 Simulator offers a multi-instance feature that most simulators on the market do not.
• From a single master Skydel instance, several Skydel slave instances running on the same hardware, can be controlled, each one representing an independent trajectory, vehicle, or antenna. This allows you perform multi-antenna GNSS simulation.
• Because they run on the same hardware, additional problems like time synchronization are solved for you.

This provides the tester with unmatched levels of control, ease, and flexibility in simulating multiple RF signals without requiring the purchase of additional hardware. The Skydel GSG-8 simulator supports up to four simultaneous instances: vehicles, trajectories, or independent signals from one device. If you need more instances, thanks to our COTS hardware-powered architecture, it’s as easy as adding more GPUs, making this the most scalable, cost-effective multi-antenna simulation solution in the world.
