ARLA/CLUSTER: Novo sistema de radio interoperável vai ser lançado a bordo da ISS

[João Costa > CT1FBF]

 ARISS closer to launching new radio system

The ARISS team took a giant step closer to flying the new ARISS
Interoperable Radio System to the International Space Station, having
met a major milestone

Lou McFadin, W5DID, and Kerry Banke, N6IZW, traveled to the NASA
Johnson Space Center (JSC) in Houston, Texas, in mid-February for
preliminary testing of Banke's breadboard version of the ARISS
Multi-voltage Power Supply. The two worked alongside JSC engineers and
JSC EMC lab personnel, putting the specially built power supply
through its paces, checking against US and Russian space
specifications for Power Quality and Electromagnetic Compatibility
(EMC) preliminary tests.

The result:  Outstanding news-the ARISS Team can move on to the next
step, fabrication of prototype and flight units.  The JSC engineers
disclosed that the ARISS breadboard power supply was the first
hardware to have passed all of the space agencies' tests!  They said
the very professional ARISS Team certainly knew hardware development
and design.

ARISS-International Chair Frank Bauer thanked Banke and McFadin for
the multiple days spent putting the unit through the serious battery
of NASA and Russian preliminary electrical tests.  Banke expressed
pleasure with the results: "I was looking to come away with what we
needed to move forward. We achieved that."  He was impressed with the
support he and McFadin received from the testing group, and said key
players on those teams who are also ham radio operators, commented
that they find equipment brought in that is supported by ham radio
operators, to earn particularly good marks.  McFadin asserted that the
Multi-voltage Power Supply's fine test results are due to ARISS's team
working very well together and being very experienced.

The completed testing of the breadboard unit means McFadin can now
purchase expensive space-certified parts so the final prototype/flight
power supplies can be fabricated.  He and Banke now know that when the
final, even more rigorous tests are done, the units will pass with
flying colors.

Watch for more news stories on the hardware and the fundraising
campaign to help support the costs associated with designing,
building, and testing the new ARISS radio system-the Kenwood D710GA
and Multi-voltage Power Supply. Those wishing to contribute toward the
final fabrication and flight tests are highly appreciated and asked to
go to the AMSAT website,  www.amsat.org, to click on the "ARISS
Donate" button.  Or visit the donation page on the ARISS website,

Contributions are tax deductible. Those who contribute $100 or more
will receive the handsome ARISS Challenge Coin.  If you or your ham
club or place of employment wish to make a highly substantial
contribution, contact Frank Bauer, KA3HDO, at ka3hdo  verizon.net
