The Trigature HF ionosonde concept
Reliable, fade-free, infrastructure-independent communication is extremely important for HF users (air/sea/ground). The Trigature next-generation ionosonde concept disrupts HF ionospheric sounding and the utilization thereof by providing precise, real-time and solid information of reliable ionospheric paths for integration into existing radio systems.
Why HF Links Are Opportunistic
HF communication is based on high-quality forecasts and models, but even today it remains fairly opportunistic: the usability of the radio path is only confirmed during the actual link establishment process, which in practice is affected by, for example, unexpected natural phenomena, local interference and deliberate jamming (electronic attack).
The Untapped Value of Ionospheric Data
Since the inception of ionospheric sounding some 80 years ago, the accumulated data has been used primarily for basic research. During this long process the understanding of relevance to HF propagation has gradually become increasingly important. However, application of this knowledge is currently being used merely for modelling and prediction and at best for delivering warnings of potential anomalies due to solar activity. Moreover, traditional ionosondes are very large, complex and fixed installations.
A Compact, Covert Next-Generation Ionosonde
Our main product is a next-generation, highly compact and rapidly redeployable digital ionosonde, which produces traditional scientific ionospheric data that refines forecasts for scientific research. Through its real-time and covert (LPI) operation, it also enables deterministic HF communication in a timely manner. This ensures users know exactly which frequencies are viable for clear, robust communication at any given moment. Furthermore, a network of this type of ionosondes can operate entirely independently of public infrastructure, with stations stealthily communicating with each other through the sounding signals themselves. For example, practically undetectable instant messaging via short encrypted messages can also be built on this platform.
Real-Time Intelligence for Reliable HF Paths
We solve the ”unreliable HF” problem by providing the intelligence needed to optimize communication paths in real-time. Our solution moves ionosounding from a static long-term scientific exercise to a dynamic tactical tool. We offer unprecedented portability and high-resolution data that enables fade-free internal communication and provides information for reliable radio paths in unpredictable environments. For defence users, this means mission-critical reliability; for commercial users, it means a scalable, cost-effective alternative to existing high-CapEx installations.
The Path to Wider Commercialization
A first-generation model of our compact ionosonde is already in commercial production use with a major customer. We are seeking seed investment and strategic partnerships with early-adopter customers to elevate this product hardware to a more production-friendly, second-generation stage with validation of our signal processing algorithms in field conditions. Finalization of our software-defined waveform deployment will result in wider commercialization of this product.
