When a User Node (UN) enters an area, where it can obtain at least 3 ranging measurements to 3 distinct NN of a LRF, a trilateration
algorithm can be performed and a solution for its relative position inside LRF can be obtained.
Your satnav's job is to use radio waves to locate the satellites, figure out the distance to each, and use this information to deduce its own location using a mathematical principle called 3D trilateration
Location can then be derived through the processes of trilateration
These two distances for each stopping location were used to compute, by way of trilateration
, the coordinates of the stopping location relative to the viewing location (see Fukusima, Loomis, & Da Silva, 1997).
This process is called trilateration
and is used by the GPS unit's receiver to calculate the latitude and longitude position of this point.
This ranging system was based on a concept termed trilateration
Spot elevations can be located by trilateration
from two grid stations.
In synergy with, and yet in stark contrast to the article in this issue on digital mapping, As it Was details some of the history of hydrography and cartography, from the earliest form of sailing directions of the 95 to 130 AD era, known as periploi, to an underwater trilateration
survey of offshore oil rig pipe lines carried out in 1976.
These include the most sophisticated automated laboratory workstations through the relatively large-scale global positioning systems that use trilateration
, a geometric principle that lets the user find one location if the distance to another location is already known.
is the determination of the relative position between points through the measurement of their separation distances.
Mobilsat is requesting two orbital positions (at about 85 and 125 degrees), saying the two will enable trilateration
for mobile vehicle position location, accurate to within 0.
