Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778 μs = 1.778 ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889 ms to transmit. The code word is repeated every 113.778 ms (4096 ÷ 36 kHz) as long as a key remains pressed.
The Department of Defense sent a MiTEx spacecraft to inspect DSP 23 sometime in 2008. [7] Another DSP satellite was lost in 1999, DSP-19, after its Inertial Upper Stage failed following launch from a Titan 4B booster. [8] DSP-19 was a USAF Defense Support Program missile early warning satellite equipped with an infrared telescope to detect ...
Indicates launch of an active radar homing missile (such as the AIM-120 AMRAAM or AIM-54 Phoenix). [1] Grumman F-14 Tomcat fires an AIM-54 Phoenix Missile | Fox Three Prior to the advent of active radar homing missiles the code "Fox three" referred to the use of guns or cannon, such as the M61 Vulcan which is used in various military aircraft.
Square Pair – fire control radar of the SA-5 system; Square Tie – surface search radar for small combatants and cruise missile target designation. [1] Chinese type 352. [2] Squat Eye – alternate target acquisition radar of the SA-3 system; Steel Yard – The Duga over-the-horizon radar; Straight Flush – fire control radar of the SA-6 system
The S753 is a tactical control radar version of the S743 with the explicit goal of reducing setup times. While the S723 required around six hours to set up, the S743 reduced this to four hours, [29] and the S753 to one hour. To aid this, the vertical coverage is reduced by removing one module, leaving 32 elements, reducing the number of ...

The former J-31 San Pedro JSS ARSR-1 radar site, California USAF Battle Control System operators monitor the skies from the floor of the program's Eastern Air Defense Sector location. The Joint Surveillance System (JSS) is a joint United States Air Force and Federal Aviation Administration system for the atmospheric air defense of North America.
The F-22 radar from Lot 5 aircraft onward is the APG-77(V)1, which draws heavily on APG-81 hardware and software for its advanced air-to-ground capabilities. [5] In August 2005, the APG-81 radar was flown for the first time aboard Northrop Grumman's BAC 1–11 test aircraft. The radar system had accumulated over 300 flight hours by 2010.
