Description

Известны способы гидрографического обследовани  рельефа морского дна по промерным галсам судна совмещеннел с одной пз линий положени , с последовательным использованием нескольких разномасштабных планшетов.Methods are known for hydrographic survey of the seabed topography along the vessel s measuring tacks combined with one pz of position lines, with the sequential use of several different-scale plates.

Предлагаемый способ отличаетс  от известных , что обследование ведут в пропессе выдерживани  курса промерного судна по двум лини м положени  с обработкой результатов наблюдени  на одном планшете . Это позвол ет производить гидрографическое обследование без прокладки места сто нки судна и исключает процесс последовательного составлени  нескольких крупномасшл-абных планшетов, что существенно ускор ет производство и обработку .материалов обследовани The proposed method differs from the known ones that the survey is carried out in the process of keeping the course vessel of the measuring vessel on two lines of position with the processing of the observation results on one tablet. This allows hydrographic surveys without laying the vessel’s parking space and eliminates the process of sequentially compiling several large-scale tablets, which significantly speeds up the production and processing of survey materials.

Наибольший эффект от применени  способа может быть иолучен в том случае, если в комплект коордннируюн1,ей апиаратуры входит прибор дл  удержани  судна на одной линии положени  - изофазометр (например, в отечественной радионавигационной системе - «Координатор , в английской системе - «Декка). Одиако способ может быть применен и при отсутствии такого прибора. В последнем случае удержание судна на изофазе производитс  с помощью обычного счетно-илшущего устройства.The greatest effect from the application of the method can be obtained if the kit includes coordinator1, it includes a device for keeping the vessel in one line of position — an isophasometer (for example, in the Russian radio navigation system — Coordinator, in the English system — Decca). Odiako method can be applied in the absence of such a device. In the latter case, the vessel is held at isophase by means of a conventional counting device.

На основном планшете промера выдел ют участок, подлежащий обследованию , и определ ют, вдоль какого семейства изофаз целесообразно расположить основные галсы. Нредпочтенпе следует отдать более помехоустойчивому каналу с большей дл-мои волны. Границами участка со всех сторон выбирают подход щие изофазы. Сн в с планшета значени  граиичных изофаз и рассто ние между ними, определ ют интервал между планируемыми галсами в фазовых циклах с тем, чтобы обеспечить на местности выбранные междугалсовые рассто ни . В заключение составл ют табличку значений изофаз, по которым будут расположены галсы обследовани . Планируемые галсы могут быть в карандаше нанесены на мелкомасштабный планшет основного промера. После этого начинают промер по выбранным изофазам, ограничива  галс значени ми граничных изофаз второго семейства. Отсчеты по этому второму каналу или, ио крайней мере, отметки времеии на фазограммс(отсечки) делают с новышенной частотой по сравнению с иромсром на основном планшете. Эта операци  может быть поручена вахтенному технику-гидрографу или.On the main measurement plate, the area to be examined is determined, and it is determined along which family of isophases it is advisable to place the main tacks. Generally, you should give a more robust channel with a greater for-wave. The boundaries of the site select suitable isophases from all sides. From the tablet, the values of the gradient isophases and the distance between them determine the interval between the planned tacks in the phase cycles in order to ensure the selected intergall distance on the ground. Finally, a tabulation of the values of the isophases is made, on which the survey tacks will be located. Planned tacks can be applied in a pencil on a small-scale main measurement plate. After that, the measurement of selected isophases begins, limiting the tack to the values of the boundary isophases of the second family. The readings on this second channel or, and at least, the time stamps on the phasograms (cut-offs) are made with a new frequency compared to the volume on the main tablet. This operation may be entrusted to the watch hydrographic technician or.
