Geographic Information Systems (GIS)

GPS, or Global Positioning System, is a satellite-based navigation system that provides location and time information anywhere on Earth. Developed by the U.S. Department of Defense, it uses a network of satellites to transmit signals, allowing GPS receivers to calculate precise positions.

GNSS, or Global Navigation Satellite System, is a broader term that encompasses all satellite navigation systems, including GPS, Russia's GLONASS, the European Union's Galileo, and China's BeiDou. GNSS offers global coverage and enhanced accuracy by integrating signals from multiple satellite networks, providing more reliable and precise positioning information across the globe.

GPS vs. GNSS

GPS: specific satellite navigation system developed by the United States

GNSS: A collective term for all the satellite navigation systems
