GPS is a United States satellite-based radio navigational, positioning, and time transfer system operated by the Department of Defense (DOD). The system provides highly accurate position and velocity information and precise time on a continuous global basis to an unlimited number of properly-equipped users. The GPS constellation of 24 satellites is designed so that a minimum of five are always observable by a user anywhere on earth. The GPS receiver uses data from a minimum of four satellites to yield a three dimensional position (latitude, longitude, and altitude) and time solution.
How many satellites make up the Global Positioning System (GPS)? 24.
What is the minimum number of Global Positioning System (GPS) satellites that are observable by a user anywhere on earth? 5.
How many Global Positioning System (GPS) satellites are required to yield a three dimensional position (latitude, longitude, and altitude) and time solution? 4. |
