From the center to outer edge of the FGS field of view is 14.1 arcminutes [1] This is a diagram of the field of view of each Hubble Space Telescope instrument, including the three FGS instruments (FGS field of view(s) highlighted in yellow) A Fine Guidance Sensor being refurbished between servicing missions SM3A and SM4 A fine guidance sensors in space on STS Servicing Mission 2 in 1997
Astrionics is the science and technology of the development and application of electronic systems, subsystems, and components used in spacecraft.The electronic systems on-board a spacecraft are embedded systems and include attitude determination and control, communications, command and telemetry, and computer systems.
A vortex flowmeter has the following components: A flow sensor operable to sense pressure variations due to vortex-shedding of a fluid in a passage and to convert the pressure variations to a flow sensor signal, in the form of an electrical signal; and a signal processor operable to receive the flow sensor signal and to generate an output signal corresponding to the pressure variations due to ...
It was created by compiling 1.3 million VNIR images taken by ASTER using single-pass [13] stereoscopic correlation techniques, [8] with terrain elevation measurements taken globally at 30-meter (98 ft) intervals.
In May 1997, USS Arthur W. Radford received the first-ever shipboard installation of the AEM/S System, to serve as a proof-of-concept or advanced technology demonstrator. [ 1 ] : 29 Sailors reported an unanticipated benefit of being able to work aloft in bad weather, increasing the efficiency of scheduled shipboard maintenance.
Usually, utility submetering is placed in situations where the local utility cannot or will not individually meter the utility in question. Municipal Utility companies are often reluctant to take on metering individual spaces for several reasons. One reason is that rental space tenants tend to be more transient and are more difficult to collect ...
A tractor being mechanically repaired in Werneuchen, 1966 Field repair of aircraft engine (1915–1916). The technical meaning of maintenance involves functional checks, servicing, repairing or replacing of necessary devices, equipment, machinery, building infrastructure and supporting utilities in industrial, business, and residential installations.
A space–time code (STC) is a method employed to improve the reliability of data transmission in wireless communication systems using multiple transmit antennas. STCs rely on transmitting multiple, redundant copies of a data stream to the receiver in the hope that at least some of them may survive the physical path between transmission and ...
