After installation on buoys, geomagnetic electronic compasses often suffer from measurement errors in azimuth angles due to manufacturing errors and magnetic interference from the buoy structure. This paper presents a two-step compensation method for azimuth measurement errors of electronic compass based on rotational step error fitting. In the first step, before installation on the buoy, the magnetometer of the electronic compass is calibrated using the ellipsoidal fitting method, which requires arbitrary rotation of the lightweight compass around multiple different axes. In the second step, after mounting the electronic compass inside the buoy, stepwise rotations are performed to collect azimuth measurement errors at various angles. The least squares method is then applied to fit the developed error function relative to rotation angle to generate compensation values for various azimuths, which are used for secondary error compensation. Experimental results demonstrate that using azimuth angles calculated by high-precision satellite positioning devices as absolute reference values, the measurement accuracy of azimuth angles reaches 0.6° after applying the proposed compensation method to the electronic compass. This approach avoids the use of three-dimensional rotation operations or large Helmholtz coils and is therefore simple and suitable for field operation.</div></div>","PeriodicalId":34311,"journal":{"name":"Measurement Sensors","volume":"41 ","pages":"Article 101971"},"PeriodicalIF":0.0,"publicationDate":"2025-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145048510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CPMI framework processes real-time temperature and strain measurements from strategically placed FBG sensors during charge-discharge cycles to estimate battery capacity degradation and determine maintenance requirements. The proposed system employs a support vector-based classification algorithm that categorizes operational states based on FBG sensor data streams, identifying deviations from optimal temperature and voltage ranges. This classification approach generates a quantitative maintenance index that enables systematic assessment scheduling rather than arbitrary inspections. Experimental validation over 200 charge-discharge cycles demonstrates the CPMI system's effectiveness, achieving a maintenance state identification accuracy of 0.95, 75 % classification success rate, classification latency of 0.1 s, precision exceeding 0.95, and an assessment reliability of 0.98.

Using a controlled variable method in simulation, the frequency boundary between high-frequency noise and useful signals was identified. After applying a low-pass filter with a cutoff frequency of 10 kHz, the simulation results indicated that the processed signal provides sufficiently accurate travel information. On the hardware side, a specialized signal conditioning circuit was designed for the acceleration sensor signals, and its effectiveness was verified through Machette hammer experiments.
