99 -- GPS USER EQUIPMENT CONFERENCE The NAVSTAR Global Positioning System (GPS) Joint Program Office (JPO) herewith provides the following information. As a part of the effort to advise the GPS JPO on a comprehensive plan for GPS modernization, the GPS JPO has asked the Boeing Corporation to survey user equipment (UE) implications of proposed changes to the military signal planned for future GPS spacecraft. Manufacturers of military GPS User Equipment are invited to a Conference for the purpose of soliciting industry comments on these proposed signal changes. The DoD has been conducting trades to determine optimum solutions for identified deficiencies in the GPS systems performance with regard to anti-jam capability, security and compatibility with military denial concepts. A military signal construct is being proposed that adds new military codes within the existing GPS bandwidth on L1 (1575MHz) and L2 (1227MHz). Additional civil signals are also being contemplated at L2 and a new frequency 1176Mhz. Implementation of these new signals is planned to begin on GPS satellites scheduled for launch in the 2003 to 2005 time-frame. The objective of the conference is to inform manufacturers of military GPS user equipment of these plans and provide an opportunity for questions and comments. The meeting will consist of two parts: (1) a general session to present descriptions of the proposed signal designs and implementation plans and (2) an optional one hour private session between Government, government representatives and individual UE manufacturers for questions and answers. The general session will take place between 9:00AM and 11:30AM on 29 June. Individual sessions may be scheduled by advanced request only for one hour sessions that will occur between 12:30PM on 29 June and continue through 5:15PM on 30 June. The meetings will be hosted at The Boeing Company at 2600 Westminster Blvd, Seal Beach, CA, Building 81. The meeting agenda is as follows: Tuesday, June 29 MORNING: (0900-1130) -- Informational Briefing  Modernization Presentations  Break  Questions/Answer Session AFTERNOON: (1230-1715) -- Individual Sessions  1230 -- 1330  1345 -- 1445  1500 -- 1600  1615 -- 1715 Wednesday, June 30 MORNING: (0800-1130) -- Individual Sessions  0800 -- 0900  0915 -- 1015  1030 -- 1130 AFTERNOON: (1230-1715) -- Individual Sessions  1230 -- 1330  1345 -- 1445  1500 _ 1600  1615 -- 1715 As in the past, the individual sessions will be handled on a "first come, first serve" basis. The JPO would prefer the format of the discussion be left entirely to the potential prime offeror. At this time, we do not anticipate any of the meetings will be classified. If during the individual sessions you foresee the need to discuss classified topics, please inform Lt Brian Barker at 310-363-2212. There will be a seating limitation for the general session on Tuesday morning so it is requested that each company limit attendance to 3 representatives. Also it is requested that each company send a list of the people who plan to attend both the general and the individual sessions to: Lt Brian Barker at email address Brian.Barker@losangeles.af.mil.
