# SUMMARY:

This notice announces a Global Positioning System (GPS) L2/L5 Civil Signal GPS L2/L5 Public Forum on June 29, 2001 in Washington, DC. The Department of Transportation, in cooperation with the GPS Joint Program Office (JPO), will provide information on the new civil signals being planned for the GPS L2 frequency (1227.60 MHz) and the new GPS L5 (1176.45 MHz) frequency. The information presented will be important to those in the government and industry involved in the development, production, support or use of satellite navigation products and services for the civil and military users. No new GPS JPO procurements are being announced or are anticipated in the near term for this work.

                        The agenda will be divided into a morning session (9 a.m. to 11:30 a.m.) for the GPS Program overview and L2                               ( print page 33238)                            and L5 overview presentations, and an afternoon session (1 p.m. to 4 p.m.) for technical presentations on both new signals. The morning agenda includes: Overview of GPS Modernization Program; the New L2 Civil Signal; the New L5 Civil Signal and the GPS JPO Interface Control Document (ICD) Review and Approval Process. The afternoon agenda includes: Technical Description of the Planned L2 Design; Laboratory Implementation of the New L2 Civil Signal; Technical Description of the Planned L5 Signal Design. Copies of the April 16, 2001 “NAVSTAR GPS Space Segment/User Segment L5 Interfaces (ICD-GPS-705),” the May 31, 2001 “Pre-Proposed Interface Revision Notice to ICD-GPS-200C for L2 Civil (L2C) Signal (PPIRN-200C-007)” and the briefing charts to the May 2, 2001 “GPS L2 and L5 Civil Signal Industry Day” presentations are now available on the GPS JPO public website                         *https://gps.losangeles.af.mil/​gpslibrary/​2000_​public/​2100_​html/​documents.html.*

# SUPPLEMENTARY INFORMATION:

## Background

The Global Positioning System employs a constellation of 24 satellites and associated ground stations to provide continuously transmitted world-wide positioning, navigation, and timing signals for use with appropriately configured GPS user equipment. The current generation GPS space vehicles transmit signals at the L1 and L2 frequencies. In the future, new civil signals will be transmitted on the L2 and L5 frequencies. The international civilian and military communities employ the dual use Global Positioning System.
