GPS/GIS

What is GNSS

Global Navigation Satellite System

What are the two core concepts GPS uses to calculate position

Time differences and satellite position

Two broad categories of GPS use

Navigation and data collection

Why is GPS important for people or industries today?

It provides accurate mapping and navigation for both people and industries, as well uses in surveying, data collection, and warfare and more.

What are the five other GNSS systems around the world

Galileo, GLONASS, BDS, QZSS, NAVIC

What is a Geographic Information System

A type of system that specifically processes spatial data, and a mapping system that visualizes geographic
information about features by explicitly referencing
them to locations on Earth’s surface.

Spatial

Refers to any space

Geospatial

anything that has to do with the study or practical use of how geographic features occupy or are distributed across space

Geographic

Earth’s surface and subsurface

GIS five uses (5 M’S)
