Option 1 states that the Global Positioning System (GPS) is based on a network of satellites orbiting above the Earth. This statement is correct. GPS works by using a constellation of satellites that orbit the Earth and transmit signals which are received by GPS receivers on the ground.

Option 2 states that GPS is based on the system of triangulation. This statement is correct. Triangulation is indeed used in GPS to determine the precise location of a receiver. By measuring the distances from the receiver to multiple satellites, GPS receivers can calculate their position using triangulation methods.

Option 3 states that GPS receivers provide location in terms of latitude, longitude, and altitude. This statement is correct. GPS receivers do indeed provide this information, allowing users to know their exact location coordinates and in some cases, even their altitude.

Option 4 states that GPS provides information exclusively for military operations. This statement is not correct. While GPS was initially developed by the United States Department of Defense for military purposes, it is now widely available for civilian use as well. GPS is used in various industries and applications including navigation, agriculture, transportation, and recreation.

In summary, option 4 is the correct answer as it incorrectly states that GPS provides information exclusively for military operations.
