High Frequency/Automatic Link Establishment (HF/ALE) Radio Propagation Test to Antarctica

Recent federal/military standards in the area of automatic link establishment (ALE) for HF radios have been developed that coordinate frequency selection between communicating terminals, allowing them to adapt to skywave conditions.

Description
Summary:Recent federal/military standards in the area of automatic link establishment (ALE) for HF radios have been developed that coordinate frequency selection between communicating terminals, allowing them to adapt to skywave conditions. This study focused on evaluating the utility of these state-of-the- art radios in the polar environment. A quick-look evaluation of this technology was demonstrated over a radio circuit between Christchurch, New Zealand, and McMurdo Station, Antarctica. This transauroral link, operated by the U.S. Navy for the National Science Foundation, is the primary link for all operational, logistical, and emergency communications for U.S. operations between the Antarctic and the outside world. Daily plots of the measured signal-to-noise ratio, probability of bit error, and channel quality are presented, and analyzed. Because of the initial success of this technology demonstration, additional experiments were designed for deployment in FY-1993 to answer not only operational issues, but also to collect data for further scientific studies and engineering improvements.
