Due to alimony issue of our current GPS orbiter , geodesist Mike Craymer and his team at Natural Resources Canada have reckon that the accuracy of global positioning system could start dropping by 2010 .
consort to a report unloose by the Government Accountability Office in April , the Air Force run into problems with being able to build GPS artificial satellite under budget and on schedule . For lesson , three age late from its original launch particular date , the next GPS orbiter will be plunge into domain in November 2009 .
With the ironware currently being used in space , the replacing and maintaining of satellites is crucial , especially since the current ironware we ’re using has been in field for almost two decades . If maintenance is not kept up , then GPS truth will begin to drop more and more each year .
The GAO has estimate – using reliability curvature for each operational orbiter – that the probability of keeping a 24 - artificial satellite configuration in orbit drib below 95 pct in 2010 , and could miss as low as 80 percent in 2011 and 2012 . And if the Air Force does n’t cope with its goals for the next - generation GPS III satellites , the chance drops to around 10 pct in 2017 .
Not to worry though , the GAO has arrive up with a few solvent — one of them involving international cooperation — suggest that the U.S. work with the European Union on their proposed navigation planet organization , Galileo , expected to launch in 2013 .
