"Surge rate" is the rate of displacement along an axis that is perpendicular to the local vertical axis and is coplanar with the nominal forward motion direction of the platform. Surge rate might not include changes to the "at rest" position of the platform with respect to the axis of displacement, which may change over time. "Fore" indicates that positive values of surge rate represent the platform moving forward as viewed by an observer on top of the platform facing forward. The standard name platform_surge_rate_aft should be used for data having the opposite sign convention. The standard name platform_surge_rate should be chosen only if the sign convention of the data is unknown. 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.
