Doppler Correction and Tracking in Commercial NGSO Networks

摘要

Successful implementation of Doppler correction and satellite tracking in commercialNGSO applications requires an automated solution that is transparent to the end user. Theamateur-satellite service pioneered the concept of One True Rule, and commercial systems aredesigned to implement this rule by adjusting in response to an observed downlink signal. Phasedarrays are the likely solution for space station tracking by user equipment, and the limitations ofthese arrays will be compensated for by constellation size, ensuring access to at least one NGSOsatellite above a certain elevation angle. In time, these techniques may come to be considered inthe amateur-satellite service as well, although manual correction and tracking remain valuablefor their illustration of radio principles, one of the foundations of the amateur-satellite service.
