Abstract In order to explore the application effect of atmospheric pressure altitude tracing method in the atmospheric system,the corrected sea pressure method was used to handle the principle error,and the 5-point 3-order smoothing processing combined with BP neural network was used to handle the measurement element error.The results show that the use of error correction methods can effectively improve the measurement accuracy of the barometric altitude traceability method,reducing the error to within 0.3 meters,making the barometric altitude traceability method highly applicable in specific scenarios.
