Introduction

Innovation of core technology of the standard

GB/T 42576-2023 marks that my country's Beidou high-precision chip technology has entered a systematic development stage, and its technological evolution presents three major characteristics:

Multi-frequency and multi-system integration: support BDS/GPS/GLONASS/Galileo four-system signals
Chip-level high precision: RTK positioning accuracy reaches centimeter level (≤(8+1×10^-6×D)mm)
Fully integrated design: RF baseband integrated chip power consumption <0.8W

Comparison of key technical indicators

Performance dimensions	Basic requirements	Advanced requirements	Test methods
Tracking capability	12 satellites for a single system	36 satellites for the entire system	Satellite signal simulator verification
Capture sensitivity	-133dBm(BDS)	-137.5dBm(GPS)	1dB step increment test
Positioning accuracy	5m(single point)	8mm+1ppm(RTK)	Baseline field measurement verification

Typical application scenarios

Smart driving field

Adopting RF baseband integrated chip to achieve:

Centimeter-level positioning under 515m/s high-speed dynamic
Stable output in rapid acceleration scenario at 40m/s²
Works in the full temperature range of -40℃~85℃

Innovation in test method

The standard innovatively proposes:

Triple-difference carrier phase accuracy detection method: calculated by the formula σ(k)=√[∑(Δ∇Δφ_ij²(k))/8(n-1)]
Multi-stress comprehensive test: including 150m/s² mechanical shock + 2000V electrostatic protection
Full-process environmental testing: Screening for hazardous substances based on GB/T 39560 series standards
