The 229-foot-tall (70-meter) rocket is poised for launch from pad 40 at Cape Canaveral Air Force Station in Florida at 3:55:48 p.m. EDT (1955:48 GMT) Tuesday at the opening of a 15-minute launch window.
The Lockheed Martin-built GPS 3 SV03 satellite mounted atop the rocket is the third member of an upgraded generation of GPS navigation spacecraft, featuring higher-power signals that are more resilient to jamming, and additional broadcast frequencies to make the GPS network more interoperable with other navigation satellite fleets.
Unlike SpaceX’s previous launch of a GPS payload in 2018, the mission will fly a slightly different profile to reserve fuel for landing of the Falcon 9 booster. Read our mission preview story for more information.
The timeline below outlines the launch sequence for the Falcon 9 flight with the GPS 3 SV03 spacecraft.
