Research and Innovative Technology Administration March 26, 2010 – Federal Register Recent Federal Regulation Documents

The U.S. Government is providing notice that it is actively considering several mitigation options prior to changing the health status of Global Positioning System (GPS) satellite IIR-20M (satellite vehicle number 49SVN 49) from unhealthy to healthy. The potential mitigations are each designed to reduce the impact of the unique nature of the SVN 49 signal to a portion of the user segment. The mitigations are described in an Appendix posted in the public docket. The mitigations are intended only for use with the SVN 49 satellite and will not be implemented for any other GPS satellite. Responses from this public comment period will be considered during the final decision to choose which mitigation(s) to implement.
