A High-Precision GPS/BeiDou-Synchronized Proton Precession Magneto

With the advancement of science and technology and the development of human society, there is an increasing demand for higher precision in magnetic field measurement. The proton precession magnetometer is precisely such an instrument capable of accurately measuring the geomagnetic field. As a high-precision magnetic field measuring device, it has been widely applied in high-precision magnetic surveys, mineral exploration, tectonic detection, seismic and volcanic precursor observation, engineering and environmental exploration, coalfield and hydrogeological exploration, pipeline and underground explosive detection, archaeology, petroleum and natural gas exploration, and other industries, thanks to its stable performance, compact size, ease of portability and simple operation.

This paper introduces a high-precision proton precession magnetometer developed by Beijing Orangelamp Geophysical Exploration Co., Ltd., with a detailed description and analysis of its working principle, appearance, functions, operation procedures and performance tests. This high-precision proton precession magnetometer has been widely used in the Chinese market and has received favorable feedback.

The high-precision proton precession magnetometer described in this paper adopts GPS or BDS (BeiDou Navigation Satellite System) for time synchronization, eliminating the tedious process of manual time input. In a favorable magnetic field environment, its noise level can reach 0.05 nT. Moreover, it is compatible with a dedicated free magnetic data processing software package developed by Beijing Orangelamp Geophysical Exploration Co., Ltd. The absolute error of this proton precession magnetometer is also controlled within ±0.5 nT.
