The new frequency is key to getting more acurate positions.  If you have two frequencies you can compare the effect of the ionosphere on the signals and correct for it.  The military (GPS P-Code) can already do this, hence their greater acuracy.  Problem is adding another frequency is expensive and power consuming on the reciever end.  Its also worth noting, this sat has higher power and better antenna's and thats gonna help even the oldest reciever.  Also, this is only 1 of 24 sats needed for coverage.  You are going to have to wait until 2011+ for full covarage with the new system.]]></description><dc:creator><![CDATA[KRB]]></dc:creator><pubDate>Dec 19th 2005 2:32AM</pubDate></item><item><title><![CDATA[Comments on Air Force launches new GPS IIR satellite]]></title><link>http://www.engadget.com/2005/09/28/air-force-launches-new-gps-iir-satellite/</link><guid isPermaLink="true">http://www.engadget.com/2005/09/28/air-force-launches-new-gps-iir-satellite/</guid><description><![CDATA[Actually, there are some indications that the Iraqis believed themselves to have accurate GPS area denial in the form of rooftop-type devices that could protect major buildings, air defense emplacements, etc., and thereby throw a wrench in our war planning that we would be unable to recover from.  (Though once you're putting out enough radiation to effectively jam a navigation device, you have yourself become a sort of single - point navigation beacon for something like a reprogrammed / resensored Shrike or HARM (favorite missile name ever,) radiation homing missile, so there's a difficult Catch-22 unless you can make them very cheap and distributed...)]]></description><dc:creator><![CDATA[WOV]]></dc:creator><pubDate>Dec 19th 2005 2:32AM</pubDate></item><item><title><![CDATA[Comments on Air Force launches new GPS IIR satellite]]></title><link>http://www.engadget.com/2005/09/28/air-force-launches-new-gps-iir-satellite/</link><guid isPermaLink="true">http://www.engadget.com/2005/09/28/air-force-launches-new-gps-iir-satellite/</guid><description><![CDATA[The problem is generally the maps not the GPS, the current GPS's will put you at the cords, they are just usually I half block off because of the crappy data overlaid off on the city grids]]></description><dc:creator><![CDATA[Griffon]]></dc:creator><pubDate>Dec 19th 2005 2:32AM</pubDate></item></channel></rss>
