SAE International has issued a new ‘Transmitted Enhanced Loran Signal Standard’.

Their PNT Committee has issued 3 new documents that provide technical descriptions of the signal-in-space eLoran waveform and 2 accepted data channel techniques; these include explanations and recommended practices:

    SAE9990 − Transmitted Enhanced Loran (eLoran) Signal Standard
    SAE9990/1 − Tri-State Pulse Modulation Data Channel Modulation Techniques
    SAE9990/2 − 9th Pulse Modulation Data Channel Modulation Techniques

SAE explains that there is a growing consensus supporting the development of independent, complimentary, multi-domain PNT services that can interoperate with GNSS; hence it is leading the charge to issue standards for eLoran.

It explains that the 3 documents, when combined with future SAE PNT Committee work products, will define architectures, sensors, interfaces, training and certification recommended practices, so that the commercial marketplace can continue to develop products and capabilities to provide robust and resilient PNT solutions for consumers.
