It now radiates correction signals for GPS receivers, to improve the accuracy of their location solutions.<br />(GPS signals from the satellites are subject to small perturbations as they pass through the ionosphere. At Wormleighton, and several other such stations, the signals are received and the amount of correction required to give the right location worked out for each satellite. This data is then transmitted to receivers that can make use of it so that improved positional accuracy results.)<br />The transmission from the site is on 291kHz - i.e. long wave and it uses what's known as minimal shift keying (MSK)at 100 baud.Peter Leehttps://www.blogger.com/profile/07013746639474025464noreply@blogger.com
