Simulate alternative, regional and lunar PNT signals with S-band support in PNT X
S-band is becoming a busy space for developers of position, navigation and timing (PNT) signals and equipment. With the L-band frequencies used by GPS and other GNSS constellations becoming crowded, more PNT services are taking advantage of S-band frequencies opened up by the International Telecommunications Union (ITU). That’s bringing new complexity to PNT test engineers, […]

Bring new realism to NAVWAR testing with continuous dynamic range in PNT X
Radio frequency (RF) jamming is one of the most prevalent threats to navigation equipment, especially in navigation warfare (NAVWAR) scenarios. Developers of receiver equipment therefore want to know how, realistically, the receiver will respond to the presence of jamming interference. In particular, developers often need to understand the impact on the receiver in dynamic scenarios where the […]

Build ultra-realistic PNT test scenarios with 3D terrain modeling in PNT X
Developers of positioning, navigation and timing (PNT) equipment usually have to sacrifice realism when testing with simulators in the lab. No simulator can ever replicate the true richness of the real-world environment, making field testing an important part of the development cycle. But it’s now possible to get closer to real-world conditions in the lab […]

Turn I/Q files into realistic signals with PNT X: SimIQ Spatial Awareness
Developers of positioning, navigation and timing (PNT) signals have long used the I/Q file format to record signals and interference waveforms for replay in a simulator. The ability to inject I/Q-defined transmitters into a GNSS simulator is invaluable for research and development of future signals and custom waveforms, and to evaluate their impact on systems […]

Beyond GNSS: Simulating alternative and complementary PNT signals in the lab
The ever-growing reliance on PNT technologies, and the emergence of new threats, means we need more sources of PNT to keep receivers robust and resilient. There are plenty of new sources to choose from, from PNT constellations in Low Earth Orbit (LEO) like Xona PULSAR, to Locata’s ground-based service, which offer independent backup to GNSS. […]
