Nicknamed Vespucci, in honor of the Italian explorer, the satellite is the first in a series of next-generation Global Positioning System satellites.
SpaceX said Tuesday's launch was scratched because of sensor readings on the rocket's first stage. This is the first national security launch for SpaceX.
The 26-minute launch window opens at 9:07 a.m. ET.
In the Year 2017, The Air Force had not launched any new satellites and now wants to launch one before 2018 end. The completely re-designed next generation of satellites are also eight times more resistant to jamming and can be updated while in orbit. On August 20, the satellite was brought to Cape Canaveral through a huge aircraft Air Force C-17.
The spacecraft, GPS III-SV01, is up to three times as accurate as its predecessor, according to Lockheed Martin, and today will be the first time it is sent into space. "The U.S. Space Command will integrate space capabilities across all branches of the military, it will develop the space doctrine, tactics, techniques and procedures that will enable our war fighters to defend our nation in this new era".
The full suite of GPS III satellites is expected to be operational by 2021. - The Air Force's first Lockheed Martin-built GPS III satellite was encapsulated within a SpaceX payload fairing at Astrotech on December 7 in preparation for its upcoming launch - now scheduled for tomorrow - at Cape Canaveral Air Force Station, Florida.
We're sure there is an incredible amount of disappointment for the actual scientists and engineers involved with any rocket launch delay, but it's not so bad for the rest of us. Blue Origin halted a launch from Texas because of "a ground infrastructure issue". But as launch time approached, it made the decision to stand down and the Falcon 9 was taken from the launch pad to allow engineers to get a closer look at the issue.
In addition, Arianespace, the European consortium that markets French-built Ariane and Russian-built Soyuz boosters, had to call off a Soyuz launch from French Guiana because of high winds.
For the last decade, the United Launch Alliance, or ULA, has launched all of the Air Force's space-based missions.
