The ground segment of SBIRS consists primarily of the Mission Control Station ( MCS ) at Buckley AFB, Aurora, Colorado, and the Mission Control Station Backup ( MCSB ) at Schriever AFB, Colorado Springs, Colorado.

The Space-Based Infrared System ( SBIRS ) is a consolidated system intended to meet the United States ' infrared space surveillance needs through the first two to three decades of the 21st century.

In 1994, DOD studied consolidating various infrared space requirements, such as for ballistic missile warning and defense, technical intelligence, and battlespace characterization, and it selected SBIRS to replace and enhance the capabilities provided by the Defense Support Program ( DSP ).

SBIRS is to use more sophisticated infrared technologies than the DSP to enhance the detection of strategic and theater ballistic missile launches and the performance of the missile-tracking function.

Air Force Space Command's SBIRS Wing at the Space and Missile Systems Center, Los Angeles AFB, California is responsible for development and acquisition of the satellites.

DSP satellites will be replaced by the Space-Based Infrared System ( SBIRS ) satellites.

The project was originally to have had a life of 25 satellites, but the last two have been canceled, mainly due to SBIRS.

Configuration of SBIRS systems: GEO, HEO and Low components.

The SBIRS program is designed to provide key capabilities in the areas of missile warning, missile defense and battlespace characterization.

SBIRS is an integrated " system of systems " that will include satellites in geosynchronous orbit ( GEO ), sensors hosted on satellites in highly elliptical orbit ( HEO ), and ground-based data processing and control.

A complement of satellites in low earth orbit was planned as part of the program ( SBIRS Low ), but this has been moved into the STSS program.

SBIRS continues to struggle with cost overruns, with Nunn-McCurdy breaches occurring in 2001 and 2005.

In December 2005, following the third SBIRS Nunn-McCurdy violation, the government decided to compete GEO 4 and 5, with an option to buy the GEO 3 contingent based on the performance of the first two.

Additionally, the government started a potential SBIRS High replacement program, writing out proposals in June 2006.

The first GEO satellite of the SBIRS program, GEO-1, was successfully launched from Cape Canaveral on an Atlas V rocket on May 7, 2011.

SBIRS GEO-2 is expected to be launched in 2013.

SBIRS High ( also now simply referred to as " SBIRS ") is to consist of four dedicated satellites operating in geosynchronous earth orbit, and sensors on two host satellites operating in a highly elliptical orbit.

SBIRS High will replace the Defense Support Program satellites and is intended primarily to provide enhanced strategic and theater ballistic missile warning capabilities.

SBIRS High GEO 1 was launched on May 7, 2011.

Two SBIRS sensors hosted on two classified satellites in highly elliptical orbit have already been launched, probably as part of the NROL-22 ( USA 184 ) and NROL-28 ( USA 200 ) launches in 2006 and 2008.

The prime contractor for SBIRS is Lockheed Martin, with Northrop Grumman as the major subcontractor.

Lockheed Martin also provides the satellite for SBIRS GEO.

The SBIRS Low program was originally expected to consist of about 24 satellites in low earth orbit.

Brilliant Eyes was renamed Space and Missile Tracking System ( SMTS ) and scaled back further under BMDO, and in the late 1990s it became the low earth orbit component of the Air Force's Space Based Infrared System ( SBIRS ).

Reading Atari 8-bit 130kB or 180kB disks was possible as well with special software, but the standard Atari 8-bit 90kB format, which used FM rather than MFM encoding, could not be handled by the 1571 hardware without modifying the drive circuitry as the control line that determines if FM or MFM encoding is used by the disc controller chip was permanently wired to ground ( MFM mode ) rather than being under software control.

Bamford describes the system as the software controlling the collection and distribution of civilian telecommunications traffic conveyed using communication satellites, with the collection being undertaken by ground stations located in the footprint of the downlink leg.

According to Dave Ulmer's message, the original stash was a black plastic bucket buried most of the way in the ground and contained software, videos, books, food, money, and a slingshot.

Back on the ground, the mission operations team used software containing 650, 000 lines of programming code in the orbit sequence design process ; 1, 615, 000 lines in the telemetry interpretation ; and 550, 000 lines of code in navigation.

* Open Source software, such as the Linux operating system and the Mozilla Firefox web browser, gain ground.

use this methodology to send information acquired thousands of feet below ground, while drilling, uphole to the surface sensors and the demodulation software.

Meanwhile, on the ground, numerous optical telescopes have been built or modified to incorporate robotic control software that responds immediately to signals sent through the Gamma-ray Burst Coordinates Network.

A modern system, having gained ground since the early 1990s, uses a personal computer and special software in place of much of the custom equipment.

: The 412th Test Wing plans, conducts, analyzes, and reports on all flight and ground testing of aircraft, weapons systems, software and components as well as modeling and simulation for the U. S. Air Force.

The VS operating system and all system software were built from the ground up to support interactive users as well as batch operations.

The ground system development activities create and maintain the software systems that are needed to provide these services to the astronomy community.

The lighting designer enters the light plot into the visualization software and then enters the ground plan of the theater and set design, giving as much 3 dimensional data as possible ( which helps in creating complete renderings ).

A five-month NASA investigation fully exonerated Chawla by identifying errors in software interfaces and the defined procedures of flight crew and ground control.

Countdown briefly halted at T-31 seconds when computer software failed to shut down a fuel valve line on ground support equipment.

WHILE and / or UNTIL ( in a software sense ) a condition is met ( say a signal sent from the ground ) IF / THEN

The ground segment itself was derived from the European Space Agency software kernel known as SCOS2000.

However, X3D has not received a wider ground of acceptance in other, more notable and proprietary software applications.

Increasingly, the consensus term " free and open-source software " is used by the communities at large to describe the common ground between free software and open-source software.

However, on September 23, 1999, communication with the spacecraft was lost as the spacecraft went into orbital insertion, due to ground based computer software which produced output in Imperial units of pound-seconds ( lbf × s ) instead of the specified metric units of newton-seconds ( N × s ).

It also involves taking geographic coordinates of the ground resolution cell with GPS technology and comparing those with the coordinates of the pixel being studied provided by the remote sensing software to understand and analyze the location errors and how it may affect a particular study.

The shift register contained only 8 bits but with lines tied to ground or 5V at random it could provide a random number between 0 and 255 which was sufficient security for the software.

* Secure by design, a term used in software engineering that means that the program in question has been designed from the ground up to be secure
