SpaceX to close 2018 with GPS III and first contracted US security system – NASASpaceFlight.com

SpaceX will include an impressive 21 launch-year campaign with the company's sought-after first US security mission. The launch of the spacecraft GPS III-SV01 will mark SpaceX's first competitive EELV, Evolved Expendable Launch Vehicle, contract with the US Air Force and is the first of the new generation of GPS III satellites to launch. The launch window extends Tuesday, 18 December from 09:11 – 09:35 EST (1411 – 1435 UTC). The mission will utilize a brand new Falcon 9 Block 5 rocket that flies in its interchangeable configuration, as Falcon 9's full performance is necessary to lift the GPS III satellite to its Medium Earth Orbit. GPS III Contract Price: The price of the first GPS III satellite contract traces its roots back to the day when the current Global Positioning System (GPS) reached full operating capacity on July 1 7, 1995. While the original GPS targets were met on that day, significant technical advances as well as users' demands on the newly completed system resulted in an attempt to modernize GPS. This initiative was fully supported by the White House and President Bill Clinton Administration in 1998, which initiated the GPS III program in connection with the US Congress official approval in 2000.

SpaceX will include an impressive 21 launch-year campaign with the company’s sought-after first US security mission. The launch of the spacecraft GPS III-SV01 will mark SpaceX’s first competitive EELV, Evolved Expendable Launch Vehicle, contract with the US Air Force and is the first of the new generation of GPS III satellites to launch.

The launch window extends Tuesday, 18 December from 09:11 – 09:35 EST (1411 – 1435 UTC). The mission will utilize a brand new Falcon 9 Block 5 rocket that flies in its interchangeable configuration, as Falcon 9’s full performance is necessary to lift the GPS III satellite to its Medium Earth Orbit.

GPS III Contract Price:

The price of the first GPS III satellite contract traces its roots back to the day when the current Global Positioning System (GPS) reached full operating capacity on July 1

7, 1995.

While the original GPS targets were met on that day, significant technical advances as well as users’ demands on the newly completed system resulted in an attempt to modernize GPS.

This initiative was fully supported by the White House and President Bill Clinton Administration in 1998, which initiated the GPS III program in connection with the US Congress official approval in 2000.

Under the Presidency George W. Bush, themselves The GPS III system, the technology that would be included in the satellites and the overall design of a spacecraft, was studied, leading to the contract award for construction of Lockheed Martin, with Orbital ATK and Northrop Grumman Astro Aerospace parts of the satellites.

During the construction contract, Lockheed Martin was a service provider and provided the A2100 bus structure for satellites. In addition, Orbital ATK, now Northrop Grumman Innovation Systems, provided the fuel and pressure and tanks, and Northrop Grumman Astro Aerospace provided the eight interchangeable JIB antennas.

During the administration of President Barack Obama, the Next Generation GPS Operational Control System contract was awarded to Raytheon on February 25, 2010 to build the ground control system for GPS III satellites.

The first GPS III satellite was originally launched in 2014 and was scheduled to be taken on a United Launch Alliance (ULA) Delta IV M + rocket, but late technology and construction deliveries drove the first launch to spring 2018. [19659002] The launch agreement for the first GPS III mission was awarded to ULA in January 2012.

However, after the first contract was awarded to ULA, SpaceX and Air Force reached an agreement 2015 for SpaceX to release its air force trial with the agreement that the Air Force would open national security

SpaceX’s trial followed a price, separate from the GPS III radius of satellites, to ULA from the US government for a 360000 ULA launch without competition from external sources in 2013.

In 2014, SpaceX held space against the air force in an effort to force competition in the launch market, instead of relying solely on block buy contracts, which SpaceX was considered more expensive than individual contractual payment agreements.

Later that year after the mood was released, the Air Force followed through on its promise and publicly requested fixed price contract bids for the launch of the second GPS III satellite.

The competition bidding was submitted as part of the e Air Force’s Evolved Expendable Launch Vehicle (EELV) program – the “Expendable” part is a property from the full cost of rockets. Falcon 9 is part of the EELV program, although it can be recycled and reused.

With the competitive nature of the contract, SpaceX offered a bid with Falcon 9 and ULA decided not to submit a bid which considered worries about how the air force would choose the winner and worries that they could not meet SpaceX’s low launch cost.

On April 26, 2016, the air force officially announced SpaceX’s choice to launch the second GPS III satellite.

Since then, the third, fourth, fifth and sixth GPS III satellites have undergone competitive launches, with SpaceX that won them all with their Falcon 9 rocket.

At that time, SpaceX GPS III won the contract for the second satellite in the series, it was slated to be the second launch of a GPS III satellite after the first satellites launched on ULAs Delta IV M-rocket.

One year after the contract award, the Air Force announced a rocket order replacement for the two missions in spring 2017, taking the GPS III SV01 (the first spacecraft) from the ULA Delta IV M + and placing it on Falcon 9 while taking GPS III SV-02 other spacecraft and the only SpaceX actually offered) from Falcon 9 and place it on the ULA Delta IV M +.

Replacing the rockets that the first two satellites would launch did not affect the fixed contracts awarded to the two companies, but it gave SpaceX a crucial – and one more – first: SpaceX would now be the company to start the first in the new generation GPS satellites, not the other.

Due to the change in payload order, the SpaceX mission – while the first GPS III satellite is launched – is the second contract flight. Therefore, the Air Force and SpaceX mission plot refer to this as GPS III-2, while in fact it is the first GPS III satellite (SV01).

GPS III-SV01 Market Testing and Checkout has been successfully completed in 2017, and upgrades to the SpaceX launch manifest led to launch in December 2018.

During the weeks leading to launch, SpaceX and Air Force successfully completed the integration of GPS III SV-01 on the payload adapter as well as encapsulation in Falcon 9 payload.

Like previous SpaceX missions, Falcon 9’s Static Fire was successfully completed – with a quick glance data review – just after midnight on December 14th.

Unlike most SpaceX missions, the final campaign before launch included a full-scale Mission Dress repetition – where the launch and payload management team worked through a complete flight scenario including issues thrown on them to ensure they are ready for any opportunity on the launch day.

With these obstacles, the mission eliminated the launch of its launch readiness review (LRR), which was held jointly on Monday, December 17th . The LRR was closed with permission to advance to the launch, and Falcon 9 rolled out to the launch plate at SLC-40 at the Cape Canaveral Air Force Station in Florida, Monday afternoon.

If everything goes to plan, the Falcon 9 rocket will lift from its coast launch plate at Cape Canaveral in a 24-minute launch window, extending from 09:11 – 09:35 EST (1411-1435 UTC) on Tuesday, December 18, 2018 .

A backup option is available on Wednesday, December 19th.

After being removed, Falcon 9 will count down and lead northeast from Cape to deliver GPS III-SV01 to a 55 ° slope.

Falcon 9 for this mission will use first step core B1054, a brand new Block 5 first stage as required by the Air Force Fixed Price Agreement.

Because every pound of Falcon 9 performance is required to get the 3.880 kg GPS III satellite in its Medium Earth Orbit, the B1054 will fly in a usable configuration without landing legs and no grating fines and will be disposed of in the Atlantic after separation from second stage.
