A typical altitude encoder, the ACK Technologies A-30. Note the 15-way D-type connector to send the Gillham code to the transponder and the port on the top of the case that connects to the aircraft's static pressure system. An altitude encoder takes the form of a small metal box containing a pressure sensor and signal conditioning electronics.
With sensor fusion, drift from the gyroscopes integration is compensated for by reference vectors, namely gravity, and the Earth's magnetic field. [3] This results in a drift-free orientation, making an AHRS a more cost effective solution than conventional high-grade IMUs that only integrate gyroscopes and rely on a high bias stability of the ...
Efforts in 1971 to develop the 'Mandrake' as a high-altitude interceptor (Yak-25PA) proved unsuccessful. Yakovlev Yak-26. In 1961 a series of lightened 'Mandrakes' were produced as high-altitude target drones. The Yak-25RV-I was used as a manned target for unarmed (no live fire) interception practice, the Yak-25RV-II as a remote-piloted drone.
An Air Data Inertial Reference Unit (ADIRU) is a key component of the integrated Air Data Inertial Reference System (ADIRS), which supplies air data (airspeed, angle of attack and altitude) and inertial reference (position and altitude) information to the pilots' electronic flight instrument system displays as well as other systems on the aircraft such as the engines, autopilot, aircraft ...
An inertial reference unit (IRU) is a type of inertial sensor which uses gyroscopes (electromechanical, ring laser gyro or MEMS) and accelerometers (electromechanical or MEMS) to determine a moving aircraft’s or spacecraft’s change in rotational attitude (angular orientation relative to some reference frame) and translational position (typically latitude, longitude and altitude) over a ...
Yak-40 – The first production model. Yak-40-25 Military conversion with the nose of a MiG-25R and SRS-4A Elint installation. Yak-40 Akva (Aqua) – Military conversion with nose probe, pylon-mounted sensors, a fuselage dispenser and underwing active jammer pods. Yak-40D (Dal'niy – long-distance) – with non-stop flight distance enlarged.
STS-120 delivered the Harmony module and reconfigured a portion of the station in preparation for future assembly missions. [2] STS-120 was flown by Space Shuttle Discovery , and was the twenty-third Space Shuttle mission to the ISS.
The dipole antenna of a radar altimeter of 1947. A radar altimeter (RA), also called a radio altimeter (RALT), electronic altimeter, reflection altimeter, or low-range radio altimeter (LRRA), measures altitude above the terrain presently beneath an aircraft or spacecraft by timing how long it takes a beam of radio waves to travel to ground, reflect, and return to the craft.
