There was also Tachi-28, a radar-based aircraft guidance set.

(Aircraft guidance and information-processing systems both utilize technology similar to the REG.)

Aircraft guidance is provided by the ILS receivers in the aircraft by performing a modulation depth comparison.

The avionics were also to have triplicated components for reliability and to allow "majority 2:1 voting" for aircraft guidance during automatic approaches and landings.

Fehse studied mechanics and aircraft guidance, navigation and control at the Technical University of Berlin (Germany), where he received his master's degree in 1965.

Called Ultrakurzwellen-Landefunkfeuer (LEF) or, commonly, Lorenz beam, this system was sold worldwide for aircraft guidance and blind landing.

The defense unit, whose sales of $1.7 billion were about 13 percent of the company's total last year, makes missile and aircraft guidance and detection systems, night-vision equipment and the like.

In 1936 his equipment automatically guided an airplane from Paris to Réunion island off the coast of Madagascar, in the first practical demonstration of an aircraft guidance system.

The primary modification for the AN/MSQ-77 was the control equipment for aircraft guidance (ballistic computer, guidance/release circuitry, and UHF command equipment).

He transformed the company into one with multimillion-dollar Government contracts to produce electronic components for military intelligence, electronic warfare, aircraft guidance, reconnaissance and navigations systems as well as communications and data systems.

That allows American and European firms to sell mid-range computers, aircraft guidance systems, oscilloscopes and other high-technology goods to former Warsaw Pact nations at will, even though such goods can also be used to design, test and navigate missiles and other weapons.

Ledley started to use SEAC himself for his dental research, but after proving an adept programmer and troubleshooter, he found himself working with SEAC (and later DYSEAC) full-time on a wide variety of projects, including a remote-controlled aircraft guidance system.

Subsequent snooping revealed that between '42 and '45, the assets of the Magna Corporation had quadrupled, due to successful bidding for thousands of government defense contracts: Magna had been the armed forces' prime supplier of bombers, aircraft guidance systems, antiaircraft weapons, tanks and halftracks, even K-ration kits and servicemen's uniforms.
