Helix Geospace
Helix Geospace is developing a range of small form factor, high-performance, antennas for use in a wide range of demanding telecommunications and navigation applications including GNSS, Internet of Things (IoT), autonomous vehicles/driverless cars, drone delivery platforms, LEO satellite communications, personal body-worn devices and Machine-to-Machine (M2M) communications. Our Dielectric-loaded Multi-filar Antennas (DMAs) for GNSS applications enable the 10cm dynamic accuracy that will be demanded for driverless cars, UAS, aerospace and many other safety critical applications where reliance of smart systems and autonomy will prevail. Our multi-frequency DMAs support GPS, Galileo, Glonass and Beidou constellations, with highly focused phase centre, and high common-mode noise rejection. They are immune to multi-path effects caused by reflections in city environments, and are also resilient to interference, jamming and electrostatic discharge. The ceramic substrate concentrates the electric field, minimising near-fuel effects. DMA antennas are designed for rugged applications, so are ideal for military, aerospace and automotive products.
