Space Micro announced today that its Proton200k Computer is part of the winning solution selected by the Air Force Research Laboratory's (AFRL) Space Vehicles Directorate, located at Kirtland Air Force Base, NM, for engineering design and development support for the Autonomous Nanosatellite Guardian Evaluating Local Space (ANGELS) satellite program.

The announced award is for the ANGELS Phase 3 Option effort from Preliminary Design Review (PDR) through Critical Design Review (CDR), August 2006 through August 2007.

Following completion of the CDR, the Air Force will pursue a follow-on contract for production of a protoflight unit.

Space Micro is part of the team led by Lockheed Martin Space Systems Company (LMSSC) that also includes Space Dynamics Laboratory, a division of the Utah State University Research Foundation of Logan, Utah; the Charles Stark Draper Laboratory of Cambridge, Massachusetts; and Lockheed Martin Integrated Systems and Solutions (LMIS and S), Valley Forge, Pennsylvania.

"Our approach to the ANGELS program has been to select the best components and teaming partners to assure Mission Success," said Stanley O. Kennedy, Jr., Senior Manager - Surveillance and Navigation Programs at LMSSC. "Space Micro's combination of experience in radiation-hardened electronic solutions, and the performance of their Proton200k computing platform, have proven to be valuable assets which are ensuring our team to continue to perform on this program."

The Proton200k computer is the fastest, low-power radiation-hardened computer available in the industry today. Based upon a 6700-class digital signal processor from Texas Instruments, it is capable of 900 MFLOPS (million floating-point operations per second) performance at a Single Event Upset (SEU) rate of 1E-4 unrecoverable errors/day using only 5-7 Watts of power.

The Proton200k also has a total dose tolerance of greater than 100 krad (Si). Protection from SEUs is achieved using Space Micro's patent-pending Time-Triple Modular Redundancy (TTMR) approach, while Single Event Functional Interrupts (SEFIs) are mitigated using the patent-pending H-Core (Hardened Core) technology.

David Czajkowski, COO of Space Micro, commented, "The Proton200k computer's combination of high performance, low power, and small size provides a radiation-hardened computing platform which we believe is unmatched in the industry today. We are pleased to be able to offer this to the Air Force as part of the Lockheed Martin ANGELS Team, and to add this program to the list of agencies and customers that have selected Space Micro as their supplier of choice for high-performance space-qualified hardware."

Proba-3 Guides ESA's First Steps Towards Formation flying
Paris France (ESA) Aug 09, 2006
Proba-3 is the third in ESA's series of missions for validating developments in space systems while carrying an 'added value' user payload which can directly benefit from the innovations under test. roba-3 will demonstrate the technologies required for formation flying of multiple spacecraft. An instrument to observe the solar corona is being used for the ongoing design phase.
