Proportional navigation (also known as PN or Pro-Nav) is a guidance law (analogous to proportional control) used in some form or another by most homing air target missiles. [1] It is based on the fact that two vehicles are on a collision course when their direct line-of-sight does not change direction as the range closes. PN dictates that the ...

Pursuit guidance, or a pursuit course, is a form of guidance widely used in older guided missiles.. In pursuit guidance, the missile is steered so that the velocity vector of the missile always points at the target, i.e. it has always the direction of the line of sight.
The navigational algorithms are the quintessence of the executable software on portable calculators or smartphones as an aid to the art of navigation, this attempt article describe both algorithms and software for smartphones implementing different calculation procedures for navigation. The calculation power obtained by the languages—Basic, C ...
Constant bearing, decreasing range (CBDR) is a term in navigation which means that some object, usually another ship viewed from the deck or bridge of one's own ship, is getting closer but maintaining the same absolute bearing. If this continues, the objects will collide. [1] [2] [3]

Pseudo-range multilateration, often simply multilateration (MLAT) when in context, is a technique for determining the position of an unknown point, such as a vehicle, based on measurement of biased times of flight (TOFs) of energy waves traveling between the vehicle and multiple stations at known locations.
Proportional-fair scheduling is a compromise-based scheduling algorithm.It is based upon maintaining a balance between two competing interests: Trying to maximize the total throughput of the network (wired or not) while at the same time allowing all users at least a minimal level of service.
