117Table 6.3-2Additional L1CO Overlay Code Parameter Assignments (Sheet 7 of 7).......... 118viiIS-GPS-800D24 Sep 20131 INTRODUCTION1.1 ScopeThis Interface Specification (IS) defines the characteristics of a signal transmitted from GlobalPositioning System (GPS) satellites to navigation receivers on radio frequency (RF) link 1 (L1).While there are multiple signals broadcast within the frequency band of L1, this IS defines onlythe signal denoted L1 Civil (L1C).
Throughout this document, the L1 carrier denotes 1575.42MHz.1.2 Interface DefinitionUtilizing the L1 open link defined in this document, GPS space vehicles (SVs), except BlockII/IIA, IIR/IIR-M, and IIF SVs, shall transmit continuous earth coverage L1C signal thatprovides the ranging codes and the system data needed to accomplish the navigation mission toall users having RF visibility to SVs and suitable receivers.1.3 IS Approval and ChangesThe GPS Directorate (SMC/GP) is the necessary authority to make this IS effective. SMC/GPadministers approvals under the auspices of the Configuration Control Board (CCB), which isgoverned by the appropriate SMC/GP Operating Instruction.
The SMC/GP CCB membershipincludes the United States Department of Transportation representative for civil organizationsand public interest.The Interface Control Contractor (ICC), designated by the government, is responsible for thebasic preparation, obtaining approval, distribution, retention, and Interface Control WorkingGroup (ICWG) coordination of this IS in accordance with GP-03-001A.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 the form of a Proposed InterfaceRevision Notice (PIRN) and is responsible for coordination of PIRNs with the ICWG.
TheICWG coordinated PIRN must be submitted as an Interface Revision Notice (IRN) to the GPSDirectorate CCB for review and approval.2 APPLICABLE DOCUMENTS2.1 Applicable DocumentsThe following documents of the issue specified contribute to the definition of the interfacesbetween the GPS Space Segment (SS) and the User Segment (US), and form a part of this IS tothe extent specified herein.1IS-GPS-800D24 Sep 2013SpecificationsNoneStandardsNoneOther PublicationsIS-GPS-200 (current issue)Navstar GPS Space Segment/Navigation User InterfacesGP-03-001A (20 April 2006)GPS Interface Control Working Group Charter2.2 Reference DocumentsThe following documents are for reference only and are not controlled by the GPS Directorate:[1] T.
