The procedure for processing satellite navigation signals uses two loops of interlinked carriers. One of these uses a wide-ranging discriminator, whilst the other uses a non-wide ranging discriminator. The procedure for processing satellite navigation signals also supports supplementary modulations allowing the transmission of data which adds to the information intrinsically contained in the elementary signal. The process includes using two loops of interlinked carriers. One of these comprises a wide ranging differential DBPSK-type discriminator (115) to hold the dynamic, and the other comprises a non-wide ranging BPSK-type discriminator (117) for not correlating the code errors. Within the first carrier loop a technique of squaring (111) is used. |
