Abstract:
According to the principle of signal oddity detection, the w avelet transform is used to detect the cyc le-slip o f the GPS carrier phase observab le. The locat ion of the cycle-slip is regarded as the bizarre po int o f the signa.l The coefficient o f the w avelet transform has a max ima lmodu lus va lue. The p lace o f the cyc le-slip is ascertained by detect ing the po in t ofmax im almodulus va lue. The experimenta l data val-i date that the deg ree o f the autom atization is h igh and the place is exactw ith the w avelet transform detect ing the cycle-slip. The detection o f the doub le difference observab le is more obv ious than that of the signle d ifference observable bacause the double difference observable e lim inates the infection o f the re levant errors, and the effect is better if the cyc le-slip is b igger.
