eLORAN
Maintain Resilient Positioning, Navigation and Timing (RPNT) when GNSS cannot be trusted with the world’s smallest eLORAN antenna and receiver. Resist jamming and spoofing on operations using jam-resistant, ground-based signals in a small form factor, combined with specialised algorithms to assure performance.
Achieve terrestrial positioning resilience through ground-based transmitters rather than vulnerable satellites. Ensure 10-metre accuracy using low-frequency, high-power signals that remove dependency upon other navigation signals.
Portable RPNT Capability
GPS interference impacts military, shipping, air and critical infrastructure’s ability to operate and manoeuvre. Alternative sources of navigation and timing independent of satellite infrastructure enable increased confidence in position and navigation. While traditionally Very low frequency (VLF) antennas are physically large thus limiting deployment options, Roke’s receiver solution is ultra-low in Size, Weight and Power (SWaP) without compromising on performance.
