A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be repeatedly programmed post manufacturing. FPGAs are a subset of logic devices referred to as programmable logic devices ("PLDs"). They consist of an array of programmable logic blocks with a connecting grid, that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions. FPGAs are often used in limited (low) quantity production of custom-made products, and in research and development, where the higher cost of individual FPGAs is not as important, and where creating and manufacturing a custom circuit wouldn't be feasible. Other applications for FPGAs include the telecommunications, automotive, aerospace, and industrial sectors, which benefit from their flexibility, high signal processing speed, and parallel processing abilities.
A microprocessor is a computer processor for which the data processing logic and control is included on a single integrated circuit (IC), or a small number of ICs. The microprocessor contains the arithmetic, logic, and control circuitry required to perform the functions of a computer's central processing unit (CPU). The IC is capable of interpreting and executing program instructions and performing arithmetic operations. The microprocessor is a multipurpose, clock-driven, register-based, digital integrated circuit that accepts binary data as input, processes it according to instructions stored in its memory, and provides results as output. Microprocessors contain both combinational logic and sequential digital logic, and operate on numbers and symbols represented in the binary number system.
The PowerPC 7xx is a family of third generation 32-bit PowerPC microprocessors designed and manufactured by IBM and Motorola. This family is called the PowerPC G3 by Apple Computer, which introduced it on November 10, 1997. A number of microprocessors from different vendors have been used under the "PowerPC G3" name. Such designations were applied to Mac computers such as the PowerBook G3, the multicolored iMacs, iBooks and several desktops, including both the Beige and Blue and White Power Macintosh G3s. The low power requirements and small size made the processors ideal for laptops and the name lived out its last days at Apple in the iBook.
Secure Digital, officially abbreviated as SD, is a proprietary, non-volatile, flash memory card format the SD Association (SDA) developed for use in portable devices.
The RAD6000 radiation-hardened single-board computer, based on the IBM RISC Single Chip CPU, was manufactured by IBM Federal Systems. IBM Federal Systems was sold to Loral, and by way of acquisition, ended up with Lockheed Martin and is currently a part of BAE Systems Electronic Systems. RAD6000 is mainly known as the onboard computer of numerous NASA spacecraft.
The COSMAC is an 8-bit microprocessor family introduced by RCA. It is historically notable as the first CMOS microprocessor. The first production model was the two-chip CDP1801R and CDP1801U, which were later combined into the single-chip CDP1802. The 1802 represented the majority of COSMAC production, and today the entire line is known simply as the RCA 1802.
The Space-Based Infrared System (SBIRS) is a United States Space Force system intended to meet the United States' Department of Defense infrared space surveillance needs through the first two to three decades of the 21st century. The SBIRS program is designed to provide key capabilities in the areas of missile warning, missile defense, battlespace characterization and technical intelligence via satellites in geosynchronous Earth orbit (GEO), sensors hosted on satellites in highly elliptical orbit (HEO), and ground-based data processing and control.
Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation, especially for environments in outer space, around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear warfare.
Micro-Space was an aerospace corporation based in Denver, Colorado, founded in February 1977 by Richard P. Speck under the name Spectron Instrument Corporation. The corporation changed its name to "Micro-Space, Inc." in 1998. It was dissolved in 2011, following the death of the founder.
The RAD750 is a radiation-hardened single-board computer manufactured by BAE Systems Electronics, Intelligence & Support. The successor of the RAD6000, the RAD750 is for use in high-radiation environments experienced on board satellites and spacecraft. The RAD750 was released in 2001, with the first units launched into space in 2005.
Space Technology 5 (ST5) of the NASA New Millennium program was a test of ten new technologies aboard a group of microsatellites. Developed by NASA Goddard Space Flight Center, the three individual small spacecraft were launched together from the belly of a Lockheed L-1011 aboard the Pegasus XL rocket, on 22 March 2006. One technology involved antennas that were designed by computers using an evolutionary AI system developed at NASA Ames Research Center. The ST5 on-board flight computer, the C&DH system, was based on a Mongoose-V radiation-hardened microprocessor.
NASA spin-off technologies are commercial products and services which have been developed with the help of NASA, through research and development contracts, such as Small Business Innovation Research (SBIR) or STTR awards, licensing of NASA patents, use of NASA facilities, technical assistance from NASA personnel, or data from NASA research. Information on new NASA technology that may be useful to industry is available in periodical and website form in "NASA Tech Briefs", while successful examples of commercialization are reported annually in the NASA publication Spinoffs. The publication has documented more than 2,000 technologies over time.
GLONASS-M, also known as Uragan-M are the second generation of Uragan satellite design used as part of the Russian GLONASS radio-based satellite navigation system. Developed by ISS Reshetnev, it had its debut launch in 2003, and is in the process of being phased out. Its production finished in 2015 and its last launch was in November 2022. It is an evolution of the previous Uragan second-generation satellites, improving accuracy, increasing power, extending the design life and adding the FDMA L2OF open signal. The last eight Glonass-M spacecraft in production included the new CDMA L3OC open signal.
Time triple modular redundancy, also known as TTMR, is a patented single-event upset mitigation technique that detects and corrects errors in a computer or microprocessor. TTMR allows the use of very long instruction word (VLIW) style microprocessors in space or other applications where external sources, such as radiation, would cause an elevated rate of errors. TTMR permits triple modular redundancy (TMR) protection in a single processor.
