Marine GPS, DGPS, and WAAS Systems
The Global Positioning System (GPS) is the backbone of modern marine navigation. Originating as a U.S. Department of Defense project in the 1970s, GPS became fully operational in the 1990s, enabling precise global positioning through a constellation of 24+ satellites. The integration of DGPS (Differential GPS) and WAAS (Wide Area Augmentation System) further refined positional accuracy, reducing potential errors to under one meter — a revolution for maritime safety and efficiency.
Innovations in Marine GPS
Today’s marine GPS systems combine multiple technologies including DGPS, WAAS, and advanced satellite compasses to enhance reliability and precision. Many units now incorporate chartplotting, radar overlays, AIS data, and NMEA 2000 networking for seamless communication with other onboard systems. These innovations support safer navigation, faster route planning, and enhanced situational awareness in all maritime environments.
GPS technology has become indispensable, not just as a stand-alone system, but also as a core component in integrated navigation suites. PSI offers GPS solutions from leading brands known for rugged design, reliable signal acquisition, and marine-grade durability.
