Overview
Project Title	DELTA-DIFFERENTIAL ONE WAY RANGING (DELTA-DOR) OPERATIONS
Approval	Approved
Document Number	506.0
Charter	1.06 Delta-DOR Working Group
Document Type	Magenta
Description of Document	This Magenta Book specifies standard practices and message formats for use in the radiometric tracking technique of differential one-way range. Purpose is to enable interoperability for cross-support between Agencies. Configuration requirements for data acquisition and control parameters for data processing are given. Recent developments in the field include a new Pseudo-Noise modulation format for DOR signals that is not covered in the current Issue 2. This Issue 3 will update the recommended practice.
Applicable Patents	There are no patent issues for this technology that are known by the CCSDS community
Patent Comments
