Project Title

Pointing Requests Message



Document Number



2.02 Navigation Working Group

Document Type


Description of Document

The Pointing Request Message (PRM) allows space agencies and operators to exchange information in a standardized format about a requested pointing of a spacecraft. These can be requested (sequences of) changes of the attitude of the spacecraft or of an articulate spacecraft component. The PRM facilitates interoperability between space agencies; e.g., where Agency/Operator A operates a spacecraft which provides a relay for a rover operated by Agency/Operator B or where an instrument owned and operated by Agency/Operator A is embarked on a spacecraft operated by Agency/Operator B. It can be used internally within a single agency or organization as well.
