| Abstract: |
| This paper proposes a discontinuous data accuracy evaluation method ba
sed on irregular variation of time interval with regard to the short data paragr
aph and broken time line of theodolite when space TT&C ship releases beacon
balloons. It applie
s self-adaptive outlier detection method and fitting residual error method to s
olve the problem of scientifically outlier detection discontinuous data,which ef
fectively fulfills ship-borne radar distance zero value and adjustment parameter
accuracy evaluation, and realizes data accuracy evaluation based on theodolite. |
