>Speaker: Kan Sandhoo
>Topic: GPS Modernization
>
>Abstract: As an integral part of the Global Navigation Satellite System
>(GNSS), GPS provides positioning services to both military and civil GPS
>user communities. The civil GPS user community uses the Standard
>Positioning Service (SPS) broadcast at L1 (1575.42 MHz) frequencyMost of
>the military GPS user community uses the SPS for signal acquisition and
>the Precision Positioning Service (PPS) broadcast at L1 and L2 (1227.6
>MHz) frequencies for tracking. The low powered GPS signals supporting
>these services are presently very vulnerable to intentional and
>unintentional interference as well as atmospheric disturbances.
>
>Since a number of applications require better performance than offered by
>the current services, an extensive effort has been undertaken by the
>United States to augment and modernize GPS. In January 1999, as a part of
>the GPS modernization effort, the United States announced that two
>additional signals would be made available for civil use. One of these
>signals would be available at 1227.60 MHz (L2) frequency for non-safety
>critical applications. Another more robust signal will be available at
>1176.45 MHz (L5) frequency for civil aviation safety-of-life services. In
>addition, more robust signals are also being considered to support
>military applications.
>
>Currently, the United States is in the process of evaluating civil and
>military requirements for GPS applications between 2010 and 2030. This
>paper reviews the United States policies, plans, and technical issues
>associated with the modernization of GPS.

>Speaker Bio: Kanwaljit S. Sandhoo works as a Lead Engineer for the
>Center for Advanced Aviation System Development (CAASD) of the MITRE
>Corporation. He has BS in Electrical Engineering and MS in Operations
>Research. He is providing technical support to the FAA's GPS and
>Navigation Integrated Product Team. He was presented Vice President Al
>Gore's Hammer Award (June 1999) for "=85 contribution to building governme=
>nt
>that works better and costs less." Mr. Sandhoo provided technical support
>to FAA for justifying the need for a second civil frequency and its
>allocation in the Aeronautical Radio Navigation Services (ARNS) band. He
>was presented an award for significant contribution (October 2000) by the
>Institute of Navigation for "=85developing and achieving support for GNSS
>implementation and GPS protection at the World Radio Conference 2000." He
>was also presented MITRE President's Award (August 1999) for "=85
>contributions=85 that resulted in a decision that will maintain U.S.
>leadership in Satellite radio navigation well into the twenty-first
>century=85 expertise and extra effort earned you the praise of the
>Department of Defense, the Department of Transportation, and the Federal
>Aviation Administration and have helped forge a higher level of
>cooperation between these organizations." He was a Technical Chair for
>Institute of Navigation (ION) GPS-99 conference. Prior to this, he
>supported the FAA as the Deputy Satellite/CNS System Manager. He is
>presently supporting the GPS III program.
