AbstractThe first digital zenith telescope prototype(DZT-1)of China was successfully developed by National Astronomical Observatories,Chinese Academy of Sciences and Shandong University of Science and Technology at the end of 2011.Compared with classical astrometric telescopes,DZT-1 has features of small size,high automation,and high accuracy.It can be used to do classical astrometric observations as well as measurement of plumb line variation and deflection of the vertical.So DZT-1 plays a significant role in astronomy and geoscience.Although the measurement principle and method of DZT-1 are somewhat similar to classical photographic zenith tube,there are still many differences.The present paper introduces the principle,method,and procedure for processing DZT-1 star image and data,as well as the application software for astronomical latitude and longitude calculation using DZT-1 observations.The test observations and the observation results are also presented.According to the test observation results,the standard deviation of single observation is about 0.2"–0.3",and 0.07"–0.08" in term of a group observations.In conclusion,the data processing software fulfills DZT-1’s demand for data processing,guaranteeing the automation and high accuracy for DZT-1.
