IPosNav::BearingToVelocity

This method converts a bearing and two speeds to east, north, and up velocities.

Syntax

HRESULT BearingToVelocity ( const pPNVELENU pENUVel, pPNVELBEAR pBearVel );

Parameters

pENUVel

Pointer to a PNVELENU structure that contains the velocity data

pBearVel

Pointer to a PNVELBEAR structure to store the bearing data

Return Values

S_OK indicates success. E_INVALIDARG indicates that one or more arguments are invalid.

Remarks

The horizontal speed and bearing members of the PNVELBEAR structure define a velocity vector in the plane defined by the north to south and east to west axes. This method resolves that vector into northward and eastward components. A southward velocity is represented as a negative north velocity, and an westward velocity is represented as a negative east velocity.
