Iridium Satellite Time and Location – PNT Series
The Helix Geospace Iridium STL active antenna is a compact, dielectric-loaded decafilar helix antenna designed for the Iridium band. Utilising proprietary Dielectrix antenna technology, it achieves exceptional efficiency relative to its size and volume.
Engineered to receive Iridium Satellite Time and Location (STL) signals, these antennas support STL terminals in delivering global position, navigation, and timing (PNT) services that operate independently of GPS/GNSS. The secure, encrypted satellite broadcast signal is robust enough to penetrate indoor environments.
STL signals provide a dependable alternative for time augmentation and authentication, addressing vulnerabilities in GNSS, such as jamming and spoofing. They are essential for critical applications, including power grids, telecom networks, financial systems, and infrastructure requiring authenticated positional data.
The HXDC26 series is an active, receive-only Iridium antenna that allows terminals to be installed several meters away from the antenna itself. It incorporates a low-current, low-noise amplifier (LNA) alongside a pre-filter to mitigate harmonic interference from high-intensity signals.
These antennas have excellent co-to-cross polarisation characteristics, enhancing their ability to distinguish multi-path (reflected and polarisation-reversed) signals. Additionally, they are balanced and electrically isolated from the platform ground, providing robust resistance to common-mode noise and minimising performance degradation from nearby objects.
Thanks to the unique dielectric core material (patent-protected), Dielectrix antennas maintain consistent performance even when installed in compact spaces. The antenna is available in two configurations: encapsulated with a protective over mould protective radome or unencapsulated for seamless device integration.
Applications
