The sixth modernized Global Positioning System IIR-19(M) satellite was successfully launched by the U.S. Air Force from Cape Canaveral A.F.B. at 2:09 a.m., EDT, on March 15th. Aboard a United Launch Alliance Delta II rocket, the liftoff occurred from Space Launch Complex 17A—this is the Space and Missile Systems Center‘s 58th consecutive launch success and the second for the Launch and Range Systems Wing this year.
This satellite will join the constellation of 31 operational satellites on orbit as they provide global coverage and increased overall performance of GPS services to users around the world. The GPS IIR-M satellites offers new features, such as two, new military signals for improved accuracy, enhanced encryption, plus anti-jamming capabilities. A second signal provides dual frequency capability and interference resistance for the civil environs. GPS IIR-19(M) will assume plane A, slot 4 position and will replaced space vehicle number (SVN) 27. This newest of the constellation’s satellites is expected to be healthy for navigation users worldwide next month—Los Angeles Air Force Base, El Segundo, California
