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.

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.

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

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.

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.

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.

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

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.

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.

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

The SBIRS Low contract is now managed by the Missile Defense Agency ( MDA ) and has been subsequently renamed to the Space Tracking and Surveillance System ( STSS ).

In addition, Joint Tactical Ground Stations ( JTAGS ) provide deployable downlinks for SBIRS data.

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 Low's original deployment schedule was 2010, the date when its capabilities were said to be needed by the National Missile Defense System.

The primary purpose of SBIRS Low was the tracking of ballistic missiles and discriminating between the warheads and other objects, such as decoys, that separate from the missile bodies throughout the middle portion of their flights.

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.

SBIRS ground software integrates infrared sensor programs of the U. S. Air Force ( USAF ) with new IR sensors.

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.

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.

Lockheed Martin also provides the satellite for SBIRS GEO.

This group is secularist and their program tends to be technological.

Next I refer to our program in space exploration, which is often mistakenly supposed to be an integral part of defense research and development.

In the latter research program, information is available for 2,758 Cornell students surveyed in 1950 and for 1,571 students surveyed in 1952.

The intensive treatment program is working well.

But there is hope, for Conservation Commissioner Bontempo has tagged the sanctuary as the kind of place the state hopes to include in its program to double its park space.

The expense ( operating ) budget is to be a program budget, and red tape is cut to allow greater autonomy ( with the Mayor approving ) in fund transfers within a department.

The schedules are flexible so that the program can be accelerated as the public becomes more tolerant or realizes that it is something that has to be done, `` so why not now ''.

The American Medical Association is once again grinding out its tear-soaked propaganda based upon the high cost of the Veterans Administration medical program to the American taxpayer.

Four hundred million dollars of the increase is for the expanded space program, a responsibility similarly neglected by Mr. Eisenhower.

This is no criticism of them, as they obviously cannot get a half-hour program into a fifteen-minute news summary.

The property sales assistance program is designed to assist small business concerns that may wish to buy property offered for sale by the Federal Government.

In the more primitive areas, where the capacity to absorb and utilize external assistance is limited, some activities may be of such obvious priority that we may decide to support them before a well worked out program is available.

It is vitally important that the new U.S. aid program should encourage all of them, since the main thrust for development must come from the less developed countries themselves.

Thus, as a development program is being launched, commitments and obligations must be entered into in a given year which may exceed by twofold or threefold the expenditures to be made in that year.

The basic mapping phase of the program has been completed and the inventory phase is scheduled for completion July 1, 1961.

Be it enacted by the Senate and House of Representatives of the United States of America in Congress assembled, That the Secretary of the Interior is hereby authorized and directed to establish and maintain a program of stabilization payments to small domestic producers of lead and zinc ores and concentrates in order to stabilize the mining of lead and zinc by small domestic producers on public, Indian, and other lands as provided in this Act.

The Institute is engaged in an extensive program of medico-military scientific research in both morphological and experimental pathology.

The Bureau is pursuing an active program to provide a temperature scale and thermometer calibration services in the range 1.5 to 20 Af.

The first part of the new structure -- that for supporting the basic program of vocational rehabilitation services -- is described in this Section.

Prior to and since 1960 the rest of the support allotment is matched at rates related to the fiscal capacity of the State, with a pivot of 40% State ( or 60% Federal ) participation in total program costs.

The method used for computing the respective Federal and State shares in total program costs is specifically set forth in the Act.

If it is decided to make a small shift which may be required from military aid or special assistance funds, in order to carry out the purposes of the Mutual Security Act through this new peaceful program, this will be a hopeful sign to the world.

A substantial increase is estimated in the cost of operating additional communications systems in the air defense program, as well as in all programs where speed and security of communications are essential.
