The Defense Advanced GPS Receiver (DAGR)

The Defense Advanced GPS Receiver (DAGR) 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 signal. Over fifty GPS satellites such as this NAVSTAR have been launched since 1978. ... The United States Department of Defense (DOD or DoD) is the federal department charged with coordinating and supervising all agencies and functions of the government relating directly to national security and the military. ... GPS signals are the what the Global Positioning System satellites broadcast to the user segment. ...

Manufactured by Rockwell Collins, the DAGR entered production in March 2004, with the 40,000th unit delivered in September 2005. It was estimated by the news source Defense Industry Daily that, by the end of 2006, the USA and various allies around the world had issued almost $300 million worth of DAGR contracts, and ordered almost 125,000 units.^[1] It replaced the Precision Lightweight GPS Receiver (PLGR), which was first fielded in 1994. Rockwell Collins (NYSE: COL) is a large United States-based international company headquartered in Cedar Rapids, Iowa, primarily providing aviation and information technology systems, solutions, and services to governmental agencies and aircraft manufacturers. ...

Due to the COMSEC electronics inside the DAGR, it is against US federal law for any individual or organization not authorized by the National Security Agency (NSA) to purchase or be in possession of the device. When devices are no longer useful or operational, they are to be returned to an NSA-approved vendor (usually the original supplier), where they are destroyed. Communications security (COMSEC): Measures and controls taken to deny unauthorized persons information derived from telecommunications and ensure the authenticity of such telecommunications. ... The National Security Agency/Central Security Service (NSA/CSS) is the U.S. governments cryptologic organization. ...
