Trilateration is the process of finding a point from three of these distance/point pairs - strictly speaking, this is "true range" trilateration (or, more generally, multilateration), and the more widely used pseudo-range trilateration (multilateration) uses four distances instead. [[GPS]], in [[ComputerCraft]] and otherwise, is based on this process, though ComputerCraft GPS is free of almost all noise and sources of error and thus uses much simpler algorithms and can achieve near-perfect accuracy easily. -ComputerCraft GPS uses at least four GPS servers which broadcast their position when requested (an implementation detail which has led to many interesting information leaks itself, requiring development of [[passive GPS]]), with clients measuring distance and performing the trilateration computations. As all ComputerCraft wireless broadcasts provide exact distance by default, without any special design or [[time sync]] being necessary, it is also possible to use identical maths and an array of receivers to locate the sender of any wireless message. This capability has been extensively used for [[monitoring]]. \ No newline at end of file +ComputerCraft GPS uses at least four GPS servers which broadcast their position when requested (an implementation detail which has led to many interesting information leaks itself, requiring development of [[passive GPS]]), with clients measuring distance and performing the trilateration computations.
