Helix Technologies announced that it has completed intensive real-world driving trials in densely urban London, UK, demonstrating mitigation of multi path and enabling satellite satellite position fixes even in underpasses and areas where overhead sky was obscured.
The company states that its dielectric-loaded multi-filar antennas (DMAs) are resilient in GNSS-challenged environments. Designed to enable centimeter accuracy PNT from = GNSS satellite constellations, they reject multi-path signals, are immune to RF and electrical interference, common-mode noise and near-field effects, and provide protection against malicious jamming and spoofing, according to Helix. This suits them for autonomous vehicle and drone situational awareness, as well as a wide range of defense, industrial and consumer applications.
