Roll 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_roll_rate should be chosen only if the sign convention of the data is unknown. For cases where the sign convention of the roll rate is known, a standard name of platform_roll_rate_starboard_down or platform_roll_rate_starboard_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."@en ; sdo:inDefinedTermSet ; sdo:name "platform_roll_rate"@en ; sdo:termCode "SDN:P07::CFSN0443" .
