Spirent’s 6th-generation simulation system, PNT X, offers an unrivaled 2 kHz software and hardware update rate as standard.
A 2 kHz simulation iteration rate provides PNT X users with the ability to improve accuracy of simulated trajectories without compromising performance. This is of particular benefit to military high-dynamic applications, such as space missions and hypersonic or spinning vehicles, such as missiles. A high-rate iteration of the simulation motion models and pseudorange calculations is needed to allow determination of spin rotational direction. PNT X supports execution of these calculations against current scenario run-time at 0.5 millisecond intervals.
The 2 kHz simulation iteration rate also produces a lower latency rate for hardware-in-the-loop (HIL) testing and faster conversion from digital inputs to RF analog outputs. In an Inside GNSS article, this is explained: “Some customers use a simulator to generate the vehicle dynamics, for an aircraft for example. They send all the PVT information to the simulator, the simulator has to read the message, apply it to the simulation and then generate the RF signals on top of that. By doubling the update rate, we are making all the steps in this process much faster, so we decrease the overall latency of the HIL system.”
Introducing PNT X: Our most powerful and flexible PNT simulator ever
Positioning, navigation and timing (PNT) are critical capabilities in an ever-growing range of systems – from military drones to communications satellites, and from autonomous cars to crewless container ships. Even lunar landers are now equipped with GNSS receivers. And while global navigation satellite systems (GNSS) like GPS were once the default source of space-based PNT, […]
