SpaceX Launches Air Force's Most Powerful GPS Satellite Ever Built (cbsnews.com)
A SpaceX Falcon 9 rocket roared to life and streaked away from Cape Canaveral early Sunday carrying the first in a powerful new generation of GPS navigation satellites into orbit. It was the California rocket builder's 21st launch this year and its first Pentagon-sanctioned national security mission. From a report: Propelled by 1.2 million pounds of thrust from its nine first stage engines, the 229-foot-tall rocket lifted off at 8:51 a.m. EST (GMT-5), climbing straight away from launch complex 40 at the Cape Canaveral Air Force Station. It was the 20th major rocket launch from Florida this year, the busiest pace since 1998. The launching came five days late because of a last-minute problem with first stage propellant temperatures Tuesday and stormy weather Thursday. High winds forced another 24-hour delay Saturday, but conditions were ideal Sunday and the rocket put on a spectacular show as it raced away to the northeast through a cloudless sky.
Vice President Mike Pence, chairman of the newly reconstituted National Space Council, was on hand for Tuesday's initial launch try but flew back to Washington after touring SpaceX facilities at the Kennedy Space Center. "The most important thing is that we get that rocket up safely and securely and it achieves its mission," Pence told spaceport workers. "I know this bird is going to fly and when it flies, it's going to make a difference for the security and prosperity of the American people." Pence has taken an active role in directing the Trump administration's revised national space policy, calling for establishment of a military "Space Force," increased commercial development in low-Earth orbit and continued NASA development of a huge new rocket and spacecraft to carry astronauts back to the moon.

Not much is explained about the GPS satellite in the summary, from the TFA we learn;
As it now stands, the ground control system, known as OCX, will not be fully on line until at least 2021, after the first half dozen GPS 3 navsats are in orbit.
The GPS 3 navsats will provide four civilian data streams for use by countless devices ranging from smart phones to automobiles, commercial aircraft and virtually all sectors of the transportation industry. Multiple data streams will enable receivers in aircraft, for example, to compensate for atmospheric effects that might otherwise reduce accuracy.
Another advantage for civilian users is interoperability with navigation systems launched by other nations.
The new satellites also feature encrypted channels using sophisticated anti-jamming technology intended to keep the satellites operational under electronic attack. Military signals will use so-called M-code processing, "a stronger and encrypted, military-specific GPS signal which can help users operate in jamming environments," according to the GAO.
The new satellites also feature a redesigned Nuclear Detonation Detection System, a search-and-rescue payload and other improvements.
On a long enough timeline, the survival rate for everyone drops to zero.
