Radiation Hardened Computer Platform with Reconfigurable FGPAs

The Proton300k™ computer platform is a high performance radiation hardened processing solution that meets the challenges of the harsh space environment. Several advanced technologies are brought together in the Proton300k™ to provide industry leading performance, power, and radiation hardening. The Proton300k™ computer platform can accept several reconfigurable FPGAs to accommodate a wide variety of space applications.

Need

Commercial digital signal processors (DSPs) and FPGAs suffer from radiation effects in the space environment, particularly single event upsets (SEU) and single event functional interrupts (SEFI). Furthermore, traditional radiation hardened computer suppliers have struggled to deliver performance and user-programmability while maintaining radiation hardness. The Proton300K™ utilizes Space Micro’s patent-pending Time-Triple Modular Redundancy (TTMR™) and Hardened Core (H-Core™) technologies to solve the SEU and SEFI issues commonly encountered with DSPs and FPGAs.

Highlights

In addition to its radiation hardening, the Proton300k™ has a modular architecture, so that it can accommodate a number of FPGAs as well as various memory and communication bus options. Its low power requirements also make it ideal for a wide variety of space applications.  SEU mitigation is handled with the on-board DSP. This mitigation can be turned on or off. This allows the utilization of the full power of the FPGAs during non-critical aspects of the mission, while mitigating SEUs during critical phases.

Applicability

With the capability to accept several reconfigurable FPGAs, the Proton300k™ can be customized to accommodate the needs of a variety of satellite and launch systems. This includes processing of image and sensor data, advanced algorithms, or many other applications in LEO or GEO orbits.

Telespazio VEGA UK Ltd is a private company in the European Space sector, working with Space agencies, satellite operators and manufacturers worldwide. It provides support for the full programme life-cycle  of space missions; from design to development and operations.

Founded in 1978 under the name of VEGA, it became   VEGA Space Ltd in 2010, and then Telespazio VEGA UK Ltd in March 2012.

The company can look back on 35 years' involvement in many European Space Agency mission and many other European and international programmes worldwide. 

The  Boeing 601 satellite is a body-stabilized geostationary satellite. 

The Boeing 601 was introduced in 1987 to meet anticipated requirements for high-power, multiple-payload satellites for such applications as direct television broadcasting to small receiving antennas, very small aperture terminals for private business networks, and mobile communications. The basic configuration features as many as 48 transponders and offers up to 4,800 watts. 

A more powerful version, the Boeing 601HP, made its debut in 1995. The HP versions can carry payloads twice as powerful as the classic Boeing 601 models, through such innovations as gallium arsenide solar cells, advanced battery technology, and an optional xenon ion propulsion system. The 601HP features as many as 60 transponders and provides up to 10,000 watts.

The Boeing 702 satellite is a family of geostationnary satellites designed and manufactured by the company Boeing.

Its design requirements include lower cost and high reliability. It offers a broad spectrum of modularity. A primary example is payload/bus integration. After the payload is tailored to customer specifications, the payload module mounts to the common bus module at only four locations and with only six electrical connectors. This design simplicity confers advantages. First, nonrecurring program costs are reduced, because the bus does not need to be changed for every payload, and payloads can be freely tailored without affecting the bus. Second, the design permits faster parallel bus and payload processing. This leads to the third advantage: a short production schedule.
