The Argentinian earth observation satellite ÑuSat-1 carries a linear transponder built by AMSAT Argentina. The satellite was launched 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 Descending Node (LTDN) of 10:30.
The AMSAT Argentina U/v inverting transponder, named LUSEX, has 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 is also a CW beacon at 145.900 MHz with a power output of 70 mW.
The transponder and beacon are currently active over Latin America and Europe.
The Amateur Radio on the International Space Station (ARISS) Team has donated two of its handsome ARISS Challenge Coins to the Dayton Amateur Radio Association as a 2016 Hamvention door prize. The two keepsake coins are positioned side by side in a beautiful display box so that each side of the coin is seen from either direction.
The commemorative ARISS Challenge Coin is the premium received by donors who give $100 or more to ARISS. Dayton Hamvention General Chairman Jim Tiderman, N8IDS, agreed to feature the ARISS keepsake coin by holding a special prize drawing immediately following the introduction of the winners of the 2016 Dayton Hamvention national awards at 2 pm on Sunday.
The ARISS Team kicks off its 2016 fund-raising campaign at the Dayton Hamvention to raise money for the very high cost of replacing its aging radio system on the ISS and to help defray the cost of continuing ARISS operations. This special Hamvention prize drawing is the first step of the campaign.
ARISS International Chair Frank Bauer, KA3HDO, noted the importance of this fundraising campaign: “ARISS is in need of critical upgrades of our on-orbit equipment. The radio system in the Columbus module is over 17 years old and underpowered. We need a 21st Century next generation solution. This fundraising campaign will enable these upgrades and, as a result, significantly improve ARISS operations and provide the funding necessary to better support our stakeholders and the amateur radio community.”
Those wanting to support the ARISS fundraising campaign can donate to ARISS online via the AMSAT Website, www.amsat.org (select the “ARISS Donate” button) or the ARISS web page, www.ariss.org (select the “Donate” tab). ARISS representatives will also be at the AMSAT Booth during the Hamvention with Challenge Coins ready for people ready to donate $100 or more.
Be sure to go to the Hara Arena at the Dayton Hamvention on Sunday, May 22, 2016 at 2 pm for the major door prize drawings … and good luck!
Amateur Radio on the International Space Station (ARISS) is a cooperative venture of international amateur radio societies and the space agencies that support the International Space Station (ISS). In the United States, sponsors are the Radio Amateur Satellite Corporation (AMSAT), the American Radio Relay League (ARRL), and the National Aeronautics and Space Administration (NASA). The primary goal of ARISS is to promote exploration of science, technology, engineering, and mathematics (STEM) topics by organizing scheduled contacts via amateur radio between crew members aboard the ISS and students in classrooms or informal education venues. With the help of experienced amateur radio volunteers, ISS crews speak directly with large audiences in a variety of public forums. Before and during these radio contacts, students, teachers, parents, and communities learn about space, space technologies, and amateur radio. For more information, go to: www.ariss.org, www.amsat.org , and www.arrl.org .
Broadly speaking the changes fit into the following categories:
1. Full support for Fox-1Cliff, Fox-1D and RadFXSat including better High Speed decoding and a better find signal algorithm.
2. Additional analytical capabilities so you can plot one telemetry variable against another. I hope this will inspire more people to analyze the telemetry from the spacecraft and post comments on what they see. I have put some of my own thoughts online here: http://www.g0kla.com/workbench/2016-05-07.php
3. Enhanced tools to analyze your ground station with SkyPlots for satellite measurements like Signal to Noise ratio and graphs for pass measurements. Skyplots in particular need a bit of explanation, so I have written more details here: http://www.g0kla.com/foxtelem/skyplot.php
