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, […]

How to Minimize Latency in a Hardware-in-the-Loop PNT Testbed

A GNSS simulator is an essential test instrument for dynamic platforms of all kinds. The simulator produces replica GNSS signals that are controllable and repeatable, allowing the assessment and qualification of PNT systems such as GNSS receivers. For applications where PNT capabilities are safety- and liability-critical, one goal of the test regime should be to […]

Unlocking the Potential of Commercial Satellite Navigation with SimXona

Commercial low Earth orbit (LEO) satellite constellations have the potential to introduce new positioning, navigation and timing (PNT) signals to complement existing global navigation satellite systems (GNSS), providing resilience, security, and high precision to navigation users. More than 20x closer to Earth compared to medium Earth orbit (MEO), providing stronger signals from LEO is attractive […]
