Experimental Advanced Airborne Research Lidar. NASA has identified lidar as a key technology for enabling autonomous precision safe landing of future...

station. The channel assignment specifies the carrier frequency and the spacing between the pulses. After a known delay, the transponder replies by transmitting...

Capability was later upgraded to include an air-to-air mode (A/A), where two airborne users can get relative slant-range and/or bearing information depending...

training and are equipped with telescopic sights. Modern snipers use high-precision rifles and high-magnification optics. They often also serve as scouts/observers...

and what they will look like under PBN. When separation minima and route spacing are determined using a conventional sensor-based approach, the navigation...

technology and form of electronic conspicuity in which an aircraft (or other airborne vehicles such as drones approved to fit "ADS-B Out") determines its position...

guidance kit that converts unguided bombs, or "dumb bombs", into all-weather precision-guided munitions (PGMs). JDAM-equipped bombs are guided by an integrated...

four prototypes. In April 1998, the vehicles were delivered to the XVIII Airborne Corps for a two-year evaluation with 3rd Battalion, 27th Field Artillery...

Controllers may use a radar system called secondary surveillance radar for airborne traffic approaching and departing. These displays include a map of the...

resolution was considered important to Air Force planners who preferred precision bombing but were failing to deliver it, and high hopes were put on the...

surfaces (that is, the pins and bushings) are safe from precipitation and airborne grit, many even in a sealed environment such as an oil bath. Some roller...

are several modes of interrogation, each indicated by the difference in spacing between two transmitter pulses, known as P1 and P3. Each mode produces...

savings in material costs, and improvements to quality, accuracy, and precision. Automation includes the use of various equipment and control systems...

multitude of channels. In the standards, channels are numbered at 5 MHz spacing within a band (except in the 60 GHz band, where they are 2.16 GHz apart)...

receivers P 0 {\displaystyle P_{0}} and P 1 {\displaystyle P_{1}} . The spacing between E {\displaystyle E} , P 1 {\displaystyle P_{1}} and P 0 {\displaystyle...

For dual-dependent approaches, the runway spacing requirement remains 2,500 feet, but the diagonal spacing is reduced from 1.5 nautical miles (nm) to...

series of ridges with a T-shaped cross-section interspersed with flat "spacing slots". Scopes are mounted either by sliding them on from one end or the...

which the changes in the turbulence become significant. r0 determines the spacing of the actuators needed in an adaptive optics system, and t0 determines...

geomechanical parameters, such as persistence, block size and rock joint spacing. LiDAR (Light Detection and Ranging) is a rapid surveying process that...

McDonnell Douglas DC-10 ahead of the flight. The accident led to aircraft spacing standards behind heavy aircraft. March 3, 1972 17 35 32 Mohawk Airlines...
