Abstract: In order to ensure that Chinese BeiDou satellite navigation system ru ns smoothly, the assessment of signal quality has become a significant task. Alt ernative binary offset carrier (AltBOC) is BeiDou B2 frequency signal. The acqui sition of BeiDou signal is processed in off-line mode and the evaluation is perf ormed by taking signal power spectrum, eye diagram, constellation, correlation, loss and s-curve deviation on AltBOC as signal quality evaluation parameters. Th e results illustrate that the new system signal, namely AltBOC signal, has the b est performance in code tracking precision, anti-jamming and anti-multipath.

 

 

Key words: signal quality assessment; alternative binary offset carrier(Alt-BOC ); correlation loss;s-curve bias
