Abstract :Global Satellite Navigation Systems (GNSS) have become a critical infrastructure element in both civilian and military areas of the modern world. Thanks to the high-accuracy location, time and direction data they provide in the transportation, energy, finance and security sectors, GNSS systems have a wide range of use from daily life to strategic operations. However, this widespread use has brought with it serious security threats such as being vulnerable to jammer and spoofer attacks due to weak signal structure, geopolitical dependency and systemic collapse risks. These threats make GNSS systems vulnerable, especially in electronic warfare and cyber attack environments. This article analyzes the effects of strategic dependency on GNSS on national security and emphasizes the importance of developing national terrestrial navigation systems as an alternative solution. Terrestrial systems such as eLoran, DGNSS and RTK stand out as complementary and backup to GNSS thanks to their strong signal structures, local controllability and jammer/spoofer resistance. In Türkiye, the establishment of a national terrestrial navigation infrastructure has become a necessity that must be carried out in parallel with defense industry strategies and national technology initiatives. In this regard, multi-layered navigation systems (GNSS + terrestrial + inertial systems) are suggested as a critical strategy for the sustainability of national security.
