IS-GPS-705 CRMCID Originator/Org. Page/Para Importance Comment PO Resolution & Concurrence NotesAerospace Para: 3.3.1.6 paragraph? You have specific requirements forpower. What does it add to say it’s monotonically Rationale: The sentence lets the user know there willdecreasing?be no antenna nulls between the specified angles.From: 3.3.1.6 Signal Power Levels. The SV shallprovide I5 and Q5 navigation signal strength atend-of-life (EOL), worst-case in order to meet theminimum levels specified in Table 3-III. Theminimum received power is measured at theoutput of a 3 dBi linearly polarized user receivingantenna (located near ground) at worst normalorientation, when the SV is above a 5-degreeelevation angle. The received signal levels areobserved within the in-band allocation defined inparagraph 3.3.1.1. Additional related data isprovided as supporting material in paragraph6.3.1.Final To: Suggested Change: Delete or justifyConcurrence: ConcurRationale:ICWG stakeholders need to know that therewill be no antenna nulls between thespecified angles. Concurrence: I’m willingto live with it, but having a specified powerout to 26 degrees says the same thing, so itis duplicative. 20-aug-09: commenterconcurs with resolution.166 Rhonda SlatteryAerospacePage:Para:3.3.1.7.1-2CRationale: Deletion of less-useful dataComment: The values of these parameters areupdated in SS-SS-800 to a tighter value.From: The group delay differential between theradiated L5 signal with respect to the EarthCoverage signal for users of the Space ServiceVolume is given by the Block III Space Contractor(TBD). The details are provided in TBD.Final To: Suggested Change: Add SS-SS-800 valuefor IIIA.PO Resolution: RejectRationale: These requirements do not exist in the SS-SS-800.Concurrence:Rationale: The requirements do exist in both the SSand CS specifications. They are the requirements forthe errors between two signals.If you don’t understand the comment,please call the commenter for clarificationbefore rejecting. 20-aug-09: PSICA workinggroup to take on action. AI #8 from the list.10-sept-09: this item is still under review.Item is deferred until ICWG.10/01/09: ICWG skateholders decided tochange the PO resolution to reject. 705 is arequirements document for IIF as well as III.167 Rhonda SlatteryAerospacePage:Para: 3.3.1.7.3SRationale: Consistent baseline and accurate userknowledge.Comment: Why is the space contractor for IIIATBD? Suggested Change: Remove 1st TBD orclarify where it appliesPO Resolution: AcceptRationale:10-sept-09: updated document and got ridof 1st TBD.64
IS-GPS-705 CRMCID Originator/Org. Page/Para Importance Comment PO Resolution & Concurrence NotesFrom: The group delay differential between the Concurrence: Concurradiated L5 signal with respect to the EarthCoverage signal for users of the Space Service Rationale:Volume is given by the Block III Space Contractor(TBD). The details are provided in TBD.Final To: The group delay differential between theradiated L5 signal with respect to the EarthCoverage signal for users of the Space Service areprovided in TBD.168 Rhonda SlatteryAerospacePage:Para: 3.3.1.9SRationale: The Space contractor is Lockheed, notTBDComment: Why is IIIA different from IIF? Are youleaving pointing error in IIF but not IIIA? In IS-200,all were changed to 13.8. See comments to 200.Suggested Change: See comments to 200 andmake this consistent one way or the other.From: 3.3.1.9 Signal Polarization. The transmittedsignal shall be right-hand circularly polarized(RHCP). For the angular range of ±14.3 degreesfrom boresight, L5 ellipticity shall be no worsethan 2.4 dB. Nominal values are listed in section6.3.3.PO Resolution: AcceptRationale: IIF is under contract for the originallanguage.Concurrence: ConcurRationale:Don’t understand response. IIF is oncontract for IS-GPS-200 language also, butthat was changed. 10-sept-09: ICCfollowed 200 resolution. See also comment#72 from this CRM.Final To: The transmitted signal shall be right-handcircularly polarized (RHCP). For the angular rangeof ±13.8 degrees from nadir, L5 ellipticity shall beno worse than 2.4 dB. Nominal values are listed insection 6.3.3.169 Rhonda SlatteryAerospacePage:Para: 6.2.2.2.6SRationale: Clarity of requirement and consistencyacross the baseline.Comment: Why not reference 200 like theprevious paragraphs? Suggested Change: Eitheradd reference or copy data from 200. See alsocomments there before copying.PO Resolution: AcceptRationale: as administrativeConcurrence: Concur(05/05/09) 10-sept-09: ICC updateddocument.65
