New GPS Satellite Set For Launch
On October 29, the United Launch Alliance will be sending an Atlas V 401 rocket carrying the GPS IIF-8 satellite into space, which will set new unit into semi-synchronous circular orbit around Earth. The mission, conducted for the U.S. Air Force, will launch from Space Launch Complex 41 at Cape Canaveral in Florida.
This will mark the fourth GPS satellite to be launched in 2014 as the Air Force works to replace the aging GPS constellation and help maintain steady GPS service to military and civilian users across the country. The new units are designed to have a “shelf life” of 12 years.
Features of the latest generation of GPS satellites include the following:
– Two-times greater predicted signal accuracy than heritage satellites
