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. "Pitch" means rotation of the platform in the vertical plane about its transverse/Y axis. The transverse/Y axis, also known as the "lateral axis" or "pitch axis", is an imaginary line running horizontally across the platform and through its center of gravity. In pitch motion, the leading edge of the platform moves vertically upwards while the rear moves vertically downwards, and vice versa. The quantity with standard name platform_pitch_rate is the change per unit time in the quantity with standard name platform_pitch_angle.

"Pitch rate" is the rate of rotation about an axis that is perpendicular to both the local vertical axis and the nominal forward motion direction of the platform. Pitch rate might not include changes to the "at rest" rotation of the platform with respect to the axis of rotation, which may change over time. The standard name platform_pitch_rate should be chosen only if the sign convention of the data is unknown. For cases where the sign convention of the pitch rate is known, a standard name of platform_pitch_rate_fore_down or platform_pitch_rate_fore_up should be chosen, as appropriate. 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.
