The Defense Advanced GPS Receiver (DAGR). Coordinates are for Rockwell Collins headquarters in Cedar Rapids, Iowa.. 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.
AD 47 was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Claudius and Vitellius (or, less frequently, year 800 Ab urbe condita ).
L1 and L2: −157 dBW for the C/A code signal and −160 dBW for the P(Y) code signal. L5 will be −154 dBW. Researchers from The Aerospace Corporation confirmed that the most efficient means to generate the high-power M-code signal would entail a departure from full-Earth coverage, characteristic of all the user downlink signals up until that ...
Vehicle navigation on a personal navigation assistant Garmin eTrex10 edition handheld. A satellite navigation device or satnav device, also known as a satellite navigation receiver or satnav receiver or simply a GPS device, is a user equipment that uses satellites of the Global Positioning System (GPS) or similar global navigation satellite systems (GNSS).
The C/A code, for civilian use, transmits data at 1.023 million chips per second, whereas the P code, for U.S. military use, transmits at 10.23 million chips per second. The actual internal reference of the satellites is 10.22999999543 MHz to compensate for relativistic effects [ 168 ] [ 169 ] that make observers on the Earth perceive a ...
USA-47, also known as GPS II-4 and GPS SVN-19, was an American navigation satellite which formed part of the Global Positioning System. It was the fourth of nine Block II GPS satellites to be launched, which were the first operational GPS satellites to fly.
The development of the original AN/AAR-47(V)1 began in 1983 by Loral. ATK became a second production source in the mid 90s and eventually became the prime contractor. In 1998 ATK began production of the improved AN/AAR-47(V)2 version, which added laser warning functionality. [2] As of 2005, over 5000 of these sets have been manufactured. [6]
Assisted GPS. Assisted GNSS (A-GNSS) is a GNSS augmentation system that often significantly improves the startup performance—i.e., time-to-first-fix (TTFF)—of a global navigation satellite system (GNSS).
