Falcon 9 wynosi satelitę GPS F-03 BY KRZYSZTOF KANAWKA ON 1 LIPCA
Start Falcona 9 z satelitą GPS F-03 / Credits - SpaceXTrzydziestego czerwca rakieta Falcon 9 wyniosła satelitę amerykańskiej konstelacji pozycjonowania GPS. (...)
Lot przebiegł prawidłowo i satelita GPS F-03 znalazł się na prawidłowej orbicie (w tym przypadku – średniej orbicie okołoziemskiej, MEO). Uwolnienie nastąpiło w 89 minucie po starcie.
Po wykonanej pracy pierwszy stopień Falcona 9 wylądował na platformie morskiej. W tym starcie użyto stopnia o oznaczeniu 1060 po raz pierwszy (czyli numeracja 1060.1). (...)
Satelita GPS F-03 ma masę startową blisko 3900 kg. Satelity tej serii konstelacji GPS zostały zbudowane na bazie platformy A2100 firmy Lockheed Martin. Satelity tej serii mają funkcjonować na orbicie MEO przez przynajmniej 15 lat.
Był to 88 start rakiety Falcon 9 od 2010 roku i zarazem 11 w 2020 roku.

The launch was the first by SpaceXs for the U.S. Space Force, which took over most Air Force-run space programs after its establishment as a new military service in December. The third in a new line of upgraded Global Positioning System navigation satellites flew aboard the Falcon 9 rocket, adding fresh capabilities to the GPS network while replacing an aging spacecraft launched more than 20 years ago. (...)
The spot-on orbit puts the GPS 3 SV03 spacecraft in position to use its own propulsion system in the coming weeks to circularize its orbit at an altitude of 12,550 miles, where the satellite is set to enter the operational GPS constellation as early as August, military officials said. (...)
Manufactured by Lockheed Martin, the GPS 3 SV03 satellite is set to enter service in Plane E, Slot 4 of the GPS constellation. That position is currently occupied by a
GPS satellite launched May 10, 2000, from Cape Canaveral on a Delta 2 rocket. Military officials did not say whether that satellite, which was originally designed for a 10-year mission, will be decommissioned or moved to another slot in the GPS network. (...)
The first two GPS 3-series satellites launched in December 2018 on a SpaceX Falcon 9 rocket and last August aboard a United Launch Alliance Delta 4 booster. Both were declared fully operational earlier this year.
Ladwig said the GPS 3 SV04 and SV05 spacecraft are complete and in storage awaiting launch, and the next three satellites are fully assembled and undergoing environmental testing. SV09 and SV10 are currently being assembled at Lockheed Martin’s GPS satellite factory near Denver. (...)
Tuesday’s launch also marked the first time military officials allowed SpaceX to reserve enough propellant on the rocket to land the Falcon 9’s first stage booster after a launch of a high-priority national security payload.
The Falcon 9 booster touched down on SpaceX’s drone ship “Just Read The Instructions” positioned around 400 miles (630 kilometers) northeast of Cape Canaveral in the Atlantic Ocean. (...)
SpaceX also retrieved the two halves of the Falcon 9 rocket’s payload fairing after Tuesday’s mission. Two recovery ships pulled the fairing halves from the Atlantic Ocean for potential reuse.
Mission planners modified the Falcon 9 launch profile to accommodate the booster landing.
The launch profile adjustment to make landing of the Falcon 9 booster possible ended up saving “several million dollars” for the military from the original SpaceX launch contract value of $96.5 million, according to Walter Lauderdale, mission director for the GPS SV03 launch from the Space Force’s Space and Missile Systems Center.

(...) But he cautioned that the decision to allow SpaceX to recover the booster on this mission does not mean every national security mission will be suitable for reusable rockets.
SpaceX is providing a new booster for this launch. There are currently no plans to use a previously flown booster in any future GPS launches. SpaceX is under contract to fly three more GPS missions over the next two years. (...)

The rocket lifted off at 4:10 p.m. Eastern from Cape Canaveral, Florida,
About eight minutes after liftoff, SpaceX landed the Falcon 9’s brand-new first stage on the “Just Read the Instructions” droneship stationed in the Atlantic Ocean.
This was the Falcon 9’s 87th successful mission and the 49th first stage recovered by SpaceX. It also marked the
first time the company recovered a booster following a National Security Space Launch mission.
The $568 million payload, the third GPS 3 satellite made by Lockheed Martin, separated from the rocket’s second stage approximately one hour and 29 minutes after liftoff. The satellite was deployed in a medium Earth orbit at an altitude of about 12,550 miles.
SpaceX’s
first launch of a GPS 3 satellite was on Dec. 23, 2018. Following the June 30 mission, the company is under contract to launch three more GPS 3 satellites over the next two years.
Tonya Ladwig, vice president of Lockheed Martin Space Systems’ Navigation Systems Division said GPS 3 satellites provide three times greater accuracy and up to eight times more anti-jamming power than the earlier generation of satellites. It also adds a new L1C civil signal.
The new GPS 3 will join a constellation of 31 GPS satellites currently in operation. Each satellite circles the earth twice per day.
Lockheed Martin said the new satellite is responding to commands from program engineers in the launch-and-checkout facility in Denver.
Ladwing said the satellite’s onboard liquid apogee engines will propel it towards its operational orbit in the coming days. “Once it arrives, we’ll send the satellite commands to deploy its solar arrays and antennas, and prepare the satellite for handover to Space Operations Command.”
