Standard names for platform describe the motion and orientation of the vehicle from which observations are made e.g. aeroplane, ship or satellite. The platform orientation is the direction in which the "front" or longitudinal axis of the platform is pointing (not necessarily the same as the direction in which it is travelling, called platform_course).

Standard names for "platform" describe the motion and orientation of the vehicle from which observations are made. Platforms include, but are not limited to, satellites, aeroplanes, ships, instruments and buoys. The platform orientation is the direction in which the "front" or longitudinal axis of the platform is pointing with high frequency variations (e.g. the effect of surface waves on a ship) removed. (This is not necessarily the same as the direction in which the platform is travelling, called platform_course).

Orientation is the clockwise angle with respect to North of the longitudinal (front-to-back) axis of the platform, which may be different to the platform course (which has the standard name platform_course). A "platform" is a structure or vehicle that serves as a base for mounting sensors. Platforms include, but are not limited to, satellites, aeroplanes, ships, buoys, instruments, ground stations, and masts.
