Overview
Project Title	Navigation Data Messages Overview Green Book
Approval	Approved
Document Number	500.2
Charter	2.02 Navigation Working Group
Document Type	Green
Description of Document	At the time the "Navigation Data -Definitions and Conventions" book was originally written, none of the Navigation Data Messages existed (ADM, ODM, TDM, CDM, etc.). Now, the ADM, ODM, TDM, and CDM have been developed and are in various stages of infusion. This Green Book will provide an overview for a prospective user of the messages developed by the Working Group.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments	Because this is a Green Book (Informational Report), it is not a Recommended Standard, thus there are no patent issues.
Survey of Similar Standards Documents or Projects Undertaken in Other Bodies and elsewhere in CCSDS	The material in this Green Book is unique to the CCSDS Navigation WG products, so there is no conflict with other standards organizations.
