4.1.1 Quality evaluation should be conducted by a qualified quality inspection agency. 4.1.2 Quality evaluation can only be conducted after the system has been in trial operation for more than half a year. 4.1.3 The validity period of the evaluation result is 2 years. 2 Quality level
The quality level of satellite navigation and positioning base station network is divided into four levels, from high to low: A, B, C, and D1
GB/T39614—2020
Records and reports
4.3.1 The quality evaluation records should be filled in in a timely, complete, standardized and clear manner. After the evaluators and verifiers sign, it is prohibited to change, add or delete records. For the evaluation record form, please refer to Table A.1 in Appendix A. 4.3.2 After the evaluation is completed, a quality evaluation report of the satellite navigation and positioning base station network should be prepared. The report template can be found in Figures A.1 to A.4. 5 Quality evaluation method
Quality characterization
The quality level of the satellite navigation and positioning base station network is characterized by primary and secondary indicators in percentage. 5.2
2 Evaluation indicators
See Table B.1 in Appendix B for evaluation indicators and descriptions of satellite navigation and positioning reference station network quality level. 3 Weights
The weights of the +-level and secondary quality evaluation indicators shall be set in accordance with Table 1. Table 1 Primary and secondary indicators and weight settings

Note 2: The weights of primary and secondary indicators are generally not adjusted. When otherwise specified in the system design and do not conflict with existing standards and specifications, the evaluation content can be added or deleted, and the indicator weights can be adjusted according to the proportion of the corresponding weights listed in this standard. The sum of the weights of each primary indicator (secondary indicator) after the adjustment should be 1.0. 4 Scoring method
5.4.1 Scoring mechanism
The satellite navigation and positioning base station network quality evaluation calculation adopts a weighted average scoring mechanism. 2
5.4.2 Scoring method for secondary indicators
The secondary indicators use the defect deduction method to calculate the quality level, and the deduction standards are shown in Table 2. Table 2 Indicator defect type and deduction standard
Defect type
Class I defect
Class II defect
Class III defect
Class IV defect
The secondary indicator score is scored according to the defect type and deduction standard according to formula (1): Deduction value
Sn=100-(ai×15+a2×10+as×5+a4) In the formula:
Secondary indicator score value;
GB/T39614—2020
The number of Class I defects, Class II defects, Class III defects and Class IV defects corresponding to the secondary indicator. The defect classification is shown in Table C.1 in Appendix C.
First-level indicator scoring method
First-level indicators are scored according to formula (2):
Where:
First-level indicator, second-level indicator score;
The weight of the corresponding indicator;
The number of second-level indicators included in the first-level indicator. Final system scoring method
The comprehensive score of the satellite navigation and positioning base station network quality level is scored according to formula (3): SWww.bzxZ.net
Where:
