Abstract

Regional dynamics marked by the increase in submarine operations by several countries need to be balanced with increasing Indonesia's capabilities in underwater warfare and contributing to increasing the deterrence of the country's defense system at sea. Therefore, the aim of this research is to consider the competitive dimensions of the development of submarine capabilities on the deterrence effect of a country and assess the extent of the discussion in the literature review. This research is a statement that there is no instrument for assessing the capability and sustainability of submarines in an effort to increase the deterrence effect in the ALKI II area which is linked to current dynamic developments so that this research is expected to contribute to obtaining an instrument for assessing submarine capability and the deterrence effect of submarines. in the ALKI II area.

Abstract

Global navigation satellite system (GNSS) is a multi-satellite-based navigation system, in the GNSS positioning process involves several navigation satellites such as global positioning system (GPS) which is a navigation system to bring up more observation data so that it is very useful when determining the desired parameters in a real-time data processing. In the research, an experimental study is used to determine land subsidence which is one of the vertical deformations of the earth's crust as a consequence of crustal dynamics. The result of the analysis is raw position data with the average method of detecting the height of the ellipsoid in the XYZ location area. Data collection is done by observation using the absolute method for one hour for position and fifteen days of observation for height. While the equipment used is u-blox Neo-7M, MCU TTL RS-485 module, ESP32-S Dev Kit V1 module, memory card module and real time clock (RTC). The results of the observation validation analysis are i) GPS-1 Easting 1.09 m and Northing 1.08 m, GPS-2 Easting 1.19 m and Northing 1.32 m, GPS-3 Easting 0.54 m and Northing 0.64 m while GPS-AVG GPS Easting 0.56 m and Northing of 0.64 m, ii) The results of the GPS-1 ellipsoid height analysis are 3.76 m, GPS-2 4.28 m, GPS-3 of 3.69 m, and iii) GPS AVG of 3.01 m.
