Details Status Name Description Template Definition Data References OID
Details Assigned Sun Pointing Data The Sun pointing template shall be used to convey an SC pointing request that fulfills the following conditions: a) An SC axis is pointed towards the direction of the Sun (target). b) The rotation around the SC pointed axis is left free and a rotation rate may be provided.

Details Assigned Inertial Pointing The inertial pointing template is used to convey an SC pointing request that fulfills the following conditions: a) An SC axis is pointed towards an inertial target. b) The remaining degree of freedom in the SC attitude is determined by a phase angle from a reference inertial direction to another SC axis.

Details Assigned Structure Template This is a generic template used to create user defined PRM requestes (not covered by existing predefined PRM templates). It provides the high level XML structure compatible with the CCSDS Navigation Working Group NDM/XML standard. PRM_Structure_Template.xml [ccsds-509.0-B-1] 1.3.112.4.27.11
Details Assigned Velocity Pointing With Orbital Pole Yaw Steering The velocity pointing with orbital pole yaw steering template shall be used to convey an SC pointing request that fulfills the following conditions: a) An SC axis is pointed towards the SC velocity relative to another object. b) The remaining degree of freedom in the SC attitude is determined by a phase angle from the SC orbital pole (direction of the angular momentum) with respect to the object and another SC axis.
