The intersection of these lines is the current position of the vessel. Usually, a fix is where two or more position lines intersect at any given time. If three position lines can be obtained, the resulting "cocked hat", where the three lines do not intersect at the same point, but create a triangle, gives the navigator an indication of the ...
A local positioning system (LPS) is a navigation system that provides location information in all weather, anywhere within the coverage of the network, where there is an unobstructed line of sight to three or more signaling beacons of which the exact position on Earth is known.
Dimensioning this system is very simple: considering CP as productive capacity and T as average assembly time, then N, number of working stations, is given by N=CP*T. Ottoman airplane being assembled during WWI. Even though airplane assembly is often cited as an example of fixed position system, today many airplanes go through assembly lines.
Enhanced radar positioning is a proposal for a position fixing system in maritime navigation, based on radar navigation.It is the automation of the process of determining own position by means of radar fixing, using a multitude of objects with known position as reference.
In an automobile, an embedded electronic system that controls some aspect of a vehicle (ignition, transmission, and so on). electronic design automation A system in which a computer provides assistance to the designer of a device or system. electronic engineering The profession of applying electronics to practical problems. electronic filter
Electronic navigation covers any method of position fixing using electronic means, including: Radio navigation uses radio waves to determine position by either radio direction finding systems or hyperbolic systems, such as Decca, Omega and LORAN-C. Availability has declined due to the development of accurate GNSS.
The construction industry contributes significantly to many countries' gross domestic products . Global expenditure on construction activities was about $4 trillion in 2012. In 2022, expenditure on the construction industry exceeded $11 trillion a year, equivalent to about 13 percent of global GDP. This spending was forecasted to rise to around ...
Second fix work requires a neater finish than first fix. The division of work is a convenient description because electricians, plumbers and carpenters will probably have to make two separate visits to one property under construction, at separate times. Project managers can report "first fix complete" or "second fix 50% done" and others can ...
