A velocity vector is an arrow that shows direction and speed of motion of a GPS site. The velocity vector for each site shown in Figure 2 is calculated from data like those shown in Figure 1. A vector is a mathematical construct that has a magnitude and a direction.
Velocity Calculation. Velocity refers to the speed in a given direction. Velocity refers to a vector measurement of the rate and direction of motion. The scalar or the absolute value magnitude of the velocity vector is the speed of the motion. Velocity is denoted by the symbol 'v'. Velocity is a vector physical quantity; both magnitude and direction are required to define it.
