Problems solved by technology

However, due to the lack of laboratory measurement and testing methods and testing equipment, most instruments cannot perform standardized and effective verification / calibration, and can only adopt on-site self-calibration or comparative testing methods, and there is no unified standard, resulting in the reliability and accuracy of observation data. The reliability and credibility are seriously affected, and there are great hidden dangers in the quality of the obtained data information

[0059] Examples and discussions:

[0060] The detection accuracy of the roll and pitch of the attitude sensor detection device is 0.001 degree, and the detection error after compensation is 0.005 degree.

[0061] The static accuracy of the roll and pitch of the S-108 model attitude sensor is 0.02° (RMS), and the accuracy of the up and down heave within ±10m is 5cm or 5%. The static internal accuracy of the instrument obtained through the above detection process Both the test standard deviation and the external coincidence precision test standard deviation are smaller than the corresponding precision values, meeting the precision requirements.

[0062] The dynamic accuracy of the roll and pitch of the S-108 model attitude sensor is 0.03° (RMS), and the up and down heave accuracy is 5cm or 5%. The standard deviation of the accuracy test is less than the corresponding accuracy value, which meets the accuracy requirements.

Abstract

The invention discloses a ship-borne attitude and angle sensor detection method, wherein a detected instrument is placed on a detection device based on a ship-borne attitude and angle sensor detection device; according to requirements of detection flow and method, synchronous motion of the device and the detected instrument is realized through software of an upper computer of the detection device; and comparative analysis is performed on a testing parameter value and a detection instrument observation data value by using testing platform software to obtain a detection result and output a detection report. The ship-borne attitude and angle sensor detection method belongs to original research achievement and no related literatures are available.

Description

technical field [0001] The invention relates to the technical field of marine surveying and mapping, in particular to a detection method of a shipborne attitude and angle sensor. Background technique [0002] Ocean sounding sonar equipment is an indispensable equipment in the fields of hydrographic survey, marine survey, national defense application and research, etc. With the rapid development of ocean development and monitoring, marine scientific research, ocean sounding sonar equipment has been widely used and played a huge role. However, due to the lack of laboratory measurement and testing methods and testing equipment, most instruments cannot perform standardized and effective verification / calibration, and can only adopt on-site self-calibration or comparative testing methods, and there is no unified standard, resulting in the reliability and accuracy of observation data. The reliability and credibility are seriously affected, and there are great hidden dangers in the...
