    Abstract
  • In order to comprehensively evaluate the performance of single-thread, multi-thread, and multi-coroutine in Global Navigation Satellite System (GNSS) data download, this paper uses the International GNSS Service (IGS) data center of Wuhan University as the download source and analyzes the download effects of three methods in terms of the time span and magnitude of the download file. The results show that in the process of small and medium-sized files download, multi-thread has more advantages than single-thread and multi-coroutine,while for large file downloads, the download effect of multi-coroutine is slightly better than multi-thread, and both have better performance than that of single-thread. Since GNSS data file is generally small and medium-sized file, multi-thread is more suitable for GNSS data download.
