Titolo
A New Open-Loop Multipath Mitigation Strategy Suitable to Modern GNSS Signals
Abstract
The paper presents a new multipath mitigation strategy suitable to current Global Navigation Satellite System signals (e.g. Galileo and modernized GPS), including high order Binary Offset Carrier (BOC) modulated signals. The proposed strategy differs from the other approaches in the state of the art, based on the same number of correlators (five): while the code tracking discrimination function is realized by means of a tradi-tional closed-loop architecture based on three correlators (Early, Prompt, and Late), the multipath mitigation is implemented in open-loop, exploiting the measurements of two additional correlators not directly used in the discriminator for the code tracking loop. Simulation results are provided in order to demon-strate and validate the performance and the flexibility of the pro-posed strategy in three cases: CBOC(6,1,1/11) (Galileo E1 Open Service), BPSK(1) (GPS L1 C/A) and BOCc(15,2.5) (Galileo E1a-like) modulated signals.
