Introduction

Interpretation of the core content of the standard

Test category	Key indicators	Technical points
On-site acceptance	Civil construction quality ≥95 points Equipment installation ≥97 points	Including verticality of observation pier, lightning protection grounding resistance, and equipment installation compliance inspection
Remote acceptance	12 functions + 9 performance items	Focus on verifying the reference station receiver multi-system signal acquisition capability
Operation acceptance	15 days of continuous observation	Data integrity requirements: Grade A ≥ 98%, Grade C ≥ 95%

The MW-GF combined algorithm is used for cycle slip detection. The calculation formula is:

MP_k1 = ρ_k1 - (f_k1²φ_k1 + f_k2²φ_k2)/(f_k1²-f_k2²)

The multipath error of Grade A stations is required to be ≤0.3m (elevation angle 10°)

Acceptance in stages: Strictly follow the order of on-site → remote → operation
Equipment selection: The receiver must support BDS-3 full frequency points (B1C/B2a, etc.)
Lightning protection design: Must comply with GB50057 Level 2 protection standards
