Analysis of Pulsar Time-of-Arrival Measurement Error and Dilution of Precision
Fei Chai · 2009
Pulsars' time of arrival measurement error were calculated using SNR method.The calculated pulsar which suitable for navigation was selected from pulsar database.The influence of observation time and detector area on measurement error were analyzed.Based on this,the differences of DOP analysis between GPS and pulsar navigation were given.The top ten group of pulsar were presented based on lower measurement error principle.The influence of observation time and detector area on DOP were also analyzed.
