[9] In nautical navigation, the term is generally used with manual or visual techniques, such as the use of intersecting visual or radio position lines, rather than the use of more automated and accurate electronic methods like GPS; in aviation, use of electronic navigation aids is more common.
Maintainability - Mean time to repair (hrs), often associated with system manuals including, operation, maintenance schedule and spare parts list. Environment - Indicates the expected disturbance conditions that the system may encounter during operation within its life time including Thermal, Humidity, Shock and Vibration, Cleanliness and ...
A total station or total station theodolite is an electronic/optical instrument used for surveying and building construction. It is an electronic transit theodolite integrated with electronic distance measurement (EDM) to measure both vertical and horizontal angles and the slope distance from the instrument to a particular point, and an on ...
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.
A visual positioning system can determine the location of a camera-enabled mobile device by decoding location coordinates from visual markers. In such a system, markers are placed at specific locations throughout a venue, each marker encoding that location's coordinates: latitude, longitude and height off the floor.

Both systems can utilize one or two GPS receivers. Using only one GPS receiver limits how the guidance system can orient the machine's position in respect to the site design. Using two GPS receivers gives the guidance system two points of position allowing it to calculate what angle the machine is on relative to the site plan.
