Usage of camera system for determination of pitching and rolling of sounding vessel

Naus K., Makar A.

Reports on Geodesy

2005

z. 2/73

301-307

In this article the description of usage of two cameras for determination of pitching and rolling of sounding vessel has been presented. The description includes presentation of the method of placing and calibration video cameras on the sounding vessel and the method of determination of pitching and rolling on the basis of images obtained using these cameras. The basis of this method is relationship between horizontal line of the image and the horizon line with relation to pitching and rolling.

Correlation of hydrographic surveys obtained using large sounding vessels

Makar A., Naus K.

Reports on Geodesy

Reliability of navigational charts and cells of electronic one depends on accuracy of determination of position and depth measurements, which can be obtained using DGPS, GPS-RTK and EGNOS during positioning and using hydrographic echosounder during depth measurement. The essential factor, which influences on hydrographic measurements, is correlation of determined position with position of the reflecting point on the bottom, where acoustic wave is reflected, especially during disrupted moving of the sounding vesseI. In this article the method of compensation of disruptions of the sounding vessel and correlation measured parameters during hydrographic surveys has been presented.
