RadFxSat (Fox-1B) Gets the Official OK for Flight

The RadFxSat (Fox-1B) Mission Readiness Review was held Saturday morning, April 29th, at the Cal Poly campus in front of a board representing Tyvak, Cal Poly, and NASA.
The purpose of the review is to verify that all requirements are met for a safe and successful launch and deployment. Vice President Engineering Jerry Buxton, N0JY, presented 81 PowerPoint slides covering all of the ICD (Interface Control Document) requirements, mission, operations, and deorbit.
At the conclusion of the presentation including questions answers, the panel unanimously approved RadFxSat as ready for flight. The next milestone will be integration into the P-POD with launch scheduled NET (No Earlier Than) September 23, 2017 aboard a Delta II at Vandenberg AFB.

Phase 5 / Phase 4B 5.7 GHz LNA Prototype

Continued progress with the Phase 5 (CQC) and Phase 4B satellite missions –

Marc Franco, N2UO, provided these photos showing the mechanical prototype of the 5.7 GHz LNA that AMSAT is developing for the P5 (lunar) and P4B (geosynchronous) satellites.

RadFxSat (Fox-1B) Nearing Completion

RadFxSat flight unit has been assembled and is going through various stages of testing before it is put through environmental (shock, vibe, bakeout) testing in August  for completion in early September.  Launch is scheduled for January 20, 2017.

In a recent test stop in Fox Labs for a few days, most of the testing was streamed live on YouTube to give enthusiasts an opportunity to “look over the shoulder” of VPE Jerry Buxton, N0JY as he conducted tests on the flight unit along with other Fox Engineering Team members on GoToMeeting.

RadFxSat is expected to be back in Fox Labs around August 11 for another round of tests and it is planned to have live streaming during those tests as well.

ÑuSat-1 to Carry AMSAT Argentina Linear Transponder – Launch Scheduled for May 30, 2016

The Argentinian earth observation satellite ÑuSat-1 will carry a linear transponder built by AMSAT Argentina. The satellite is scheduled to launch on a CZ-4B rocket from Taiyuan Satellite Launch Center in China on May 30, 2016 into a 500 km sun-synchronous orbit with an inclination of 97.5 degrees and a Local Time of the Ascending Node (LTAN) of 10:30.

The AMSAT Argentina U/v inverting transponder, named LUSEX, wiil have an uplink of 435.935 MHz to 435.965 MHz and a downlink of 145.935 MHz to 145.965 MHz. Total power output is 250 mW. There will also be a CW beacon at 145.900 MHz with a power output of 70 mW.

For more information, see the AMSAT Argentina Facebook group.

UPDATE:  A website with preliminiary Keplerian elements and further information is now live at http://lusex.org.ar/
