209xiiIS-GPS-200H24 Sep 20131 INTRODUCTION1.1 Scope.This Interface Specification (IS) defines the requirements related to the interface between theSpace Segment (SS) of the Global Positioning System (GPS) and the navigation User Segment(US) of the GPS for radio frequency (RF) link 1 (L1) and link 2 (L2).1.2 IS Approval and Changes.The Interface Control Contractor (ICC) designated by the government is responsible for the basicpreparation, approval coordination, distribution, retention, and Interface Control Working Group(ICWG) coordination of the IS in accordance with GP-03-001. The Navstar GPS Directorate(SMC/GP) is the necessary authority to make this IS effective.
SMC/GP administers approvalsunder the auspices of the Configuration Control Board (CCB), which is governed by theappropriate GPS Directorate Operating Instruction (OI). Military organizations and contractorsare represented at the CCB by their respective segment member. All civil organizations andpublic interest are represented by the Department of Transportation representative of theSMC/GP.A proposal to change the approved version of this IS can be submitted by any ICWGparticipating organization to the GPS Directorate and/or the ICC. The ICC is responsible for thepreparation of the change paper and change coordination, in accordance with GP-03-001. TheICC prepares the change paper as a Proposed Interface Revision Notice (PIRN) and isresponsible for coordination of PIRNs with the ICWG.
The ICWG coordinated PIRN must besubmitted to the GPS Directorate CCB for review and approval.The ICWG review period for all Proposed Interface Revisions Notices (PIRNs) is 45 days afterreceipt by individual addressees. A written request to extend the review period may besubmitted to the ICC for consideration.2 APPLICABLE DOCUMENTS2.1 Government Documents.The following documents of the issue specified contribute to the definition of the interfacesbetween the GPS Space Segment and the GPS navigation User Segment, and form a part of thisIS to the extent specified herein.1IS-GPS-200H24 Sep 2013SpecificationsFederalNoneMilitaryNoneOther Government ActivityNoneStandardsFederalNoneMilitaryNoneOther PublicationsGP-03-001 (GPS Interface Control Working Group Charter)International Earth Rotation and Reference Systems Service(IERS) Technical Note 362.2 Non-Government Documents.The following documents of the issue specified contribute to the definition of the interfacesbetween the GPS Space Segment and the GPS Navigation User Segment and form a part of thisIS to the extent specified herein.SpecificationsNoneOther PublicationsNone3 REQUIREMENTS3.1 Interface Definition.The interface between the GPS Space Segment (SS) and the GPS navigation User Segment (US)includes two RF links, L1 and L2.
