PENGARUH GANGGUAN SINYAL GPS OLEH AKTIVITAS MILITER TERHADAP KINERJA NAVIGASI KAPAL MV. GLOVIS DAYLIGHT: STUDI PADA RUTE PELAYARAN INTERNASIONAL KOREA - KANADA – KOREA

Abstract

This study investigates the impact of GPS signal disruptions caused by military activity, particularly during international voyages in geopolitically sensitive waters. Aboard MV. Glovis Daylight, significant disruptions occurred during a voyage between Canada and Korea, attributed to ballistic missile testing by North Korea. This interference caused a phenomenon known as “GPS jumping,” where the vessel’s position was incorrectly shown on land, leading to confusion, navigation errors, and potential safety hazards. Unlike previous research that primarily focused on natural interference, this study highlights military operations as a major source of GPS signal disruption. The main research objective is to examine how such disruptions influence navigational performance and maritime safety. Using a quantitative descriptive approach, data were collected through structured questionnaires and direct observations of the ship’s crew. Statistical analysis was conducted using SPSS 26. Findings reveal that GPS disruptions significantly reduce navigation accuracy, increase route deviation risks, and delay communication with shore. Around 80% of respondents confirmed that military activity had a direct operational impact on the vessel. The study concludes that missile tests and military exercises pose real threats to navigational safety in international waters. Recommendations include improving crew training, using alternative navigation systems, and establishing international protocols to manage military activity near shipping lanes.
