History of Time-Frequency Technology

Present-day collision avoidance systems (CAS) of the time-frequency variety employ modes of operation similar to those of airborne equipment which has been operating in military aircraft since 1959. A fleet operational evaluation of these systems began in 1961 in aircraft of U. S. Navy Helicopter Squadron HS-4, based on the aircraft carrier U.S.S. Yorktown. This equipment utilized a local clock in each aircraft, a separate time slot for each aircraft's interrogation signal, air-to-air coarse synchronization of all stations, and sufficient free-drift stability for time slot keeping. Operational use of one-way ranging with elimination of propagation delay offsets, higher clock stability for open-loop time keeping in the SNS-64 ... AN/APN-169 family of systems began in 1964 in U. S. Air Force C-130E turboprop aircraft. In 1965, use of the EROS I collision avoidance system began during flight testing of F-4 Phantom supersonic aircraft.     

Electronic technical manual development

In the past, Air Force technical manuals have been stored in libraries containing many volumes of such manuals. This article details the creation and development of an Electronic Technical Manual for the F-16 Analog Test Station Sustainment (FATSS) Project. The manual will allow users to search a single CD-ROM to access data on maintenance, operational procedures, self-test, calibration, schematics, and illustrated parts breakdowns     

Near term approach to data relay for satellites under test

The increasing need for a continuous communications link with U.S. Department of Defense (DoD) spacecraft during test missions in low Earth orbit (LEG) has resulted in greater interest in geosynchronous data relay services. This may be a more economical alternative to building additional remote tracking stations for the Air Force Satellite Control Network (AFSCN), and avoids tying up operational assets for a test mission. A low-cost near-term approach for such a space-based data relay system would utilize two existing Defense Satellite Communication System III spacecraft, two existing ground terminals, and a small, standardized terminal using autonomous antenna pointing for the space vehicle under test. Such a system design is presented     

Choosing software and replacing ATE: lessons learned

When tasked to ensure the Minuteman Intercontinental Ballistic Missile system remains fully operational and supportable through 2020, the Air Force realized that the support capability of its legacy automated test system for the operational ground support electronics subsystem would need to be completely replaced. The legacy test system, while fully operational, was rapidly becoming non-supportable. Unless replaced with new hardware and upgraded test program sets, the needed long-term support could not be provided to the weapon system. To address this issue within the scope of available program funding constraints, the Air Force selected an approach of combining the technical and programmatic expertise of the weapon system prime contractor, the program control responsibilities of the weapon system Program Office, and the technical capability of an Air Force technical organization. The program was divided into two phases: a prototype phase and a production/rehost phase. This paper gives an overview of the program and presents valuable lessons learned during the prototype phase.

精确空袭--美军实施"非接触作战"的王牌

扼要介绍了美国精确制导武器技术的新发展和美国空军精确空袭作战的现状和未来.     

AFRL Cryogenic Technology Development Programs

This is an overview of the cryogenic refrigerator and cryogenic integration programs in development and characterization under the Cryogenic Technologies Group, Space Vehicles Directorate of the Air Force Research Laboratory (AFRL). The vision statement for the Air Force Research Laboratory Cryogenic Technologies Group is to support the space community as the center of excellence for developing and transitioning space cryogenic thermal management technologies. The primary customers for the AFRL cryogenic technology development programs are Ballistic Missile Defense Organization (BMDO), the USAF SBIRS (space based infrared) Low program office, and DoD space surveillance programs. This describes a variety of Stirling, pulse tube, Reverse Brayton, Joule-Thomson, and Sorption cycle cryocoolers currently under development to meet current and future Air Force and DoD requirements. The AFRL customer single stage cooling requirements at 10 K, 35 K, 60 K, 150 K, and multi-stage cooling requirements at 35/60 K are addressed. In order to meet these various requirements, the AFRL Cryogenic Technologies Group is pursuing various strategic cryocooler and cryogenic integration options. The Air Force Research Laboratory is also developing several advanced cryogenic integration technologies that will result in the reduction in current cryogenic system integration penalties and design time. These technologies include the continued development of the cryogenic systems integration model (CSIM), 60 K, and 100 K thermal storage units and heat pipes, cryogenic straps, thermal switches, and development of an integrated lightweight cryogenic bus (CRYOBUS).     

GPS III system operations concepts

Over the past three years, the Lockheed Martin GPS III team has analyzed potential operational concepts for the Air Force. The completed tasks support the government's objective of a "realizable and operationally feasible" US Strategic Command (USSTRATCOM) and Air Force Space Command (AFSPC) concept of operations. This paper provides an overview of the operational improvements for the command and control of satellites, the provision of safe, precise navigation and timing services to end-users. The GPS III system changes existing operational paradigms. Improved operator capabilities are enabled by a new high-speed uplink/downlink and crosslink communication architecture. Continuous connectivity allows operators a "contact one satellite - contact all satellites" concept enabling near-real-time navigation updates and telemetry monitoring. This paper describes potential improvements for the following operations: constellation monitoring, command and control, navigation upload monitoring, global service monitoring, global service prediction, civilian navigation (CNAV) messaging, and anomaly detection and resolution. This paper also describes future operational improvements as GPS applications continue to proliferate and the need for an improved infrastructure to effectively manage all the systems that affect GPS service grows     

The Tactical Communications Satellite
