METHOD OF PROCESSING RADIONAVIGATION SIGNALS |
摘要 |
<p>The satellites of a constellation of satellites each transmit, on distinct frequencies, a first and a second radionavigation signal, respectively. Each station of a reference network from which a satellite is visible performs non-differentiated measurements of code and phase for each of the two signals originating from the satellite and deduces therefrom a raw value of the widelane ambiguity. An internal delay of the satellite and a whole value of the widelane ambiguity are determined, in the network, on the basis of this raw value. The method comprises the steps: -receiving the first and second radionavigation signals at the level of the reference receiver; -performing, with the aid of the reference receiver and for each of the first and second signals received, a non-differentiated measurement of code and a non-differentiated measurement of phase; -calculating the raw value of the widelane ambiguity on the basis of the non-differentiated measurements of code and phase; and -fixing the internal delay of the satellite and the whole value of the widelane ambiguity on the basis of the raw value for the reference receiver.</p> |
