Abstract

Science and technology continue to evolve every day, and their potential can be
maximized to facilitate human work, including the needs of scientific research. Oceanographic
data collection is a concrete example of technological utilization. Conventionally, data collection
was done manually using human labor, but technological advancements have led to the
creation of a device called a drifter. In oceanography, continuous and real-time data collection is
essential for forecasting water conditions. Location and time data collection using the GPS
UBLOX NEO 6M is utilized to obtain data on ocean current direction and speed. The
RockBLOCK Mk2 9602 satellite-based communication module is used to avoid communication
range limitations. A GPS Tracker system based on the Iridium Satellite Network has been
successfully designed and built, and testing has been conducted to measure its ability to collect
time and location data as well as its ability to transmit data using satellite communication.
Testing was carried out by comparing GPS module data with data from Google Maps, as well
as comparing data collected locally on an SD card with data collected on the Iridium server.
comparing data collected locally on an SD card with data collected on the Iridium server. The
research results show that the collected data has an average deviation of 0,36 meters.
