Comparative analysis of standard frameworks

Dimensions	Scope requirements	Implementation points
Data classification	Divided into three categories: basic information, observation data and results data.	Ensure that each type of product meets the format and content requirements, such as the use of standard formats such as RINEX and RTCM.
Accuracy requirements	The coordinate accuracy of the base station must reach the millimeter level, and the observation data interval must not exceed 1 second.	Establish a quality control process and regularly calibrate equipment and data processing systems.
Compatibility	Supports compatibility with multiple systems such as BDS, GPS, GLONASS, Galileo, etc.	Ensure that both hardware and software can support signal reception and processing of all target satellite systems.

Implementation suggestions

Site construction: - Select site strictly according to standards to ensure representative geographical location. - Use GNSS receivers and antenna equipment that meet the requirements, such as Trimble R8 or Leica GNSS receiver. Data collection and processing: - Ensure the stability of real-time transmission of observation data streams to avoid data loss. - Use professional post-processing software for data analysis and product generation, such as CASS or Trimble Business Systems. Quality Control: - Regularly calibrate equipment and check the accuracy of key parameters such as antenna elevation. - Establish a data review mechanism to ensure that the output data meets the accuracy and format requirements.
