As of 2009, military GPS applications include: Navigation: Soldiers use GPS to find objectives, even in the dark or in unfamiliar territory, and to coordinate troop and supply movement. In the United States armed forces, commanders use the Commander's Digital Assistant and lower ranks use the Soldier Digital Assistant. [141]
The AN/PSN-13 Defense Advanced GPS Receiver (DAGR; colloquially, "dagger") is a handheld GPS receiver used by the United States Department of Defense and select foreign military services. It is a military-grade, dual-frequency receiver, and has the security hardware necessary to decode the encrypted P(Y)-code GPS signals .
Blue force tracking is a United States military term for a GPS-enabled capability that provides military commanders and forces with location information about friendly (and despite its name, also hostile) military forces. In NATO military symbology, blue typically denotes friendly forces. The capability provides a common picture of the location ...
A GPS receiver in civilian automobile use. Air navigation systems usually have a moving map display and are often connected to the autopilot for en-route navigation. Cockpit-mounted GNSS receivers and glass cockpits are appearing in general aviation aircraft of all sizes, using technologies such as SBAS or DGPS to increase accuracy.
The first military use of satellites was for reconnaissance. In the United States the first formal military satellite programs, Weapon System 117L, was developed in the mid-1950s. [2] Within this program a number of sub-programs were developed including Corona. [2] Satellites within the Corona program carried different code names.
The Joint Precision Airdrop System (JPADS) is an American military airdrop system which uses the Global Positioning System (GPS), steerable parachutes, and an onboard computer to steer loads to a designated point of impact (PI) on a drop zone (DZ). The JPADS family of systems consists of several precision airdrop systems, ranging from extra ...
Autonomous air combat maneuvering instrumentation (AACMI) are second-generation GPS-based ACMI systems. Unlike first-generation ACMI systems, which use ground radars to track and record the position of the aircraft on the range, AACMI systems use aircraft-mounted satellite navigation systems such as the US NAVSTAR GPS system. Recording of ...
When GPS was first being put into service, the US military was concerned about the possibility of enemy forces using the globally available GPS signals to guide their own weapon systems. Originally, the government thought the "coarse acquisition" (C/A) signal would give only about 100- metre (330 ft ) accuracy, but with improved receiver ...
