The satellite bus is 2 49 by 2 03 by 2 24 meters in size.
Boeing gps iif satellite.
The company has constructed more than 40 gps satellites that cumulatively have provided more than 540 years of on orbit service.
As of august 2020 75 global positioning system navigation satellites have been launched 31 of which are operational 9 in reserve 3 being tested 30 have been retired and 2 were lost at launch.
The twelfth and final iif launch was february 5 2016.
Gps provides positioning navigation and timing service to civil and military users worldwide.
Gps satellites circle earth at a distance of 11 000 nautical miles.

Gps iif is the product of boeing s long legacy with gps capabilities dating back to the first gps satellite program in 1974.
The global positioning system iif is a current iteration of the gps satellite which boeing began building in 1978.
The first block iif space vehicle was launched in may 2010 on a delta iv rocket.
They were built by boeing to be operated by the united states air force being launched by united launch alliance using evolved expendable launch vehicles.
The gps iif delivers improved accuracy greater security and anti jam capabilities while maintaining baseline legacy gps performance.
The gps receiver needs 4 satellites to work out your position in 3 dimensions.
Rotating 220 miles 354 km above earth is the international space station where boeing provides a safe environment for more than 200 experiments.
Gps block iif or gps iif is an interim class of gps which are used to keep the navstar global positioning system operational until the gps block iiia satellites become operational.
The block iif series are follow on satellites developed by boeing.
They are the final component of the block ii gps constellation to be launched.
Since the first launch in 1978 boeing built gps satellites have accumulated the equivalent of more than 500 years of on orbit operation.
The constellation requires a minimum of 24 operational satellites and the official target count is 33.
In 1996 the gps iif contract was awarded to the boeing company for the development and production of 33 space vehicles svs.
The vehicles have a liftoff mass of 1 630 kilograms and are equipped with two deployable three panel solar arrays for power generation.
As the prime contractor on the gps block i block ii block iia and block iif programs boeing has built 40 of the 62 gps satellites launched since 1978.
