AMSAT Recognized for Educational Support
Escuela Técnica Superior de Ingeniería Aeronáutica y del Espacio of
Universidad Politecnica de Madrid, Spain has recognized and thanked the
members of AMSAT who have supported their educational endeavors by
collecting telemetry data downloaded from the UPMSat-2 satellite around the
globe.
Dr. Rafael García Romero, EA4BPN, along with project director Dr. Elena
Roibas and team member Dr. Angel Sanz Andres, penned the letter of
recognition dated February 17, 2023 and recently received by AMSAT. The
letter reads:
"On the celebration of UPMSat-2 launch date anniversary of the second year
in orbit, UPMSat-2 team would like to thank AMSAT for its support to the
satellite downlink data gathering.
"The effort of AMSAT members is seen at IDR as a valuable 'citizen science'
contribution to our project and is gratefully acknowledged.
"We expect that the UPMSat-2 will continue to work for another two years,
therefore, it would bring an opportunity to continue with this fruitful
collaboration.
"With our best regards, we wish all the best for AMSAT members."
UPMSat-2 sends 2-FSK data at 2400bps, with transmitted power of
approximately 2.5 watts, on 437.405 MHz. Originally scheduled to launch in
1999, it was finally launched on September 3, 2020 from the Guiana Space
Centre in Kourou, French Guiana. Launched on the flight VV16 of the Vega
rocket, it entered a sun-synchronous orbit with an altitude of
approximately 518 km.

ARDC Grant Funds FreeDV Project
To advance the state of the art in HF digital voice and to promote its use,
Amateur Radio Digital Communications (ARDC) has awarded $420,000 to the
FreeDV Project.
FreeDV is a low-bit-rate digital voice mode for HF radio. Initially
developed by David Rowe, VK5DGR, an international team of radio amateurs
are now working together on the project. FreeDV is open-source software,
released under the GNU Lesser Public License (LPGL) version 2.1. The modems
and Codec 2 speech codec used in FreeDV are also open source.
Hardware and software developers can integrate FreeDV into their projects
using the FreeDV API. To operate FreeDV, radio amateurs either run the
FreeDV GUI application on Windows, Linux and OSX machines or use the SM1000
FreeDV adaptor. Either method allows hams to use a single-sideband HF radio
to send and receive FreeDV signals. To learn more about FreeDV, go to
https://www.freedv.org.
Amateur Radio Digital Communications (ARDC) is a California-based
foundation with roots in amateur radio and the technology of internet
communication. The organization got its start by managing the AMPRNet
address space, which is reserved for licensed amateur radio operators
worldwide.
Additionally, ARDC makes grants to projects and organizations that follow
amateur radio’s practice and tradition of technical experimentation in both
amateur radio and digital communication science. Such experimentation has
led to advances that benefit the general public, including the mobile phone
and wireless internet technology. ARDC envisions a world where all such
technology is available through open source hardware and software, and
where anyone has the ability to innovate upon it. To learn more about ARDC,
go to https://www.ardc.net.

Radio Interference From Satellites Threatening Astronomy
Radio telescopes are facing a problem. All satellites, whatever their
function, use radio waves to transmit information to the surface of the
Earth. Just as light pollution can hide a starry night sky, radio
transmissions can swamp out the radio waves astronomers use to learn about
black holes, newly forming stars and the evolution of galaxies.
In a paper published March 3,2023, Christopher Gordon De Pree, Deputy
Electromagnetic Spectrum Manager, National Radio Astronomy Observatory;
Christopher R. Anderson, Associate Professor of Electrical Engineering at
the United States Naval Academy; and Mariya Zheleva, Assistant Professor of
Computer Science, University at Albany, State University of New York, call
for creation of a national radio dynamic zone.
This zone would be similar to existing radio quiet zones, covering a large
area with restrictions on radio transmissions nearby. Unlike a quiet zone,
the facility would be outfitted with sensitive spectrum monitors that would
allow astronomers, satellite companies and technology developers to test
receivers and transmitters together at large scales. The goal would be to
support creative and cooperative uses of the radio spectrum.
As the problem of radio pollution continues to grow, scientists, engineers
and policymakers will need to figure out how everyone can effectively share
the limited range of radio frequencies. One solution that astronomers have
been working on for the past few years is to create a facility where
astronomers and engineers can test new technologies to prevent radio
interference from blocking out the night sky.
Such a zone doesn’t exist yet, but our team and many people across the U.S.
are working to refine the concept so that radio astronomy, Earth-sensing
satellites and government and commercial wireless systems can find ways to
share the precious natural resource that is the radio spectrum.

House Subcommittee Advances Five Satellite-Related Bills
A U.S. House Energy and Commerce subcommittee unanimously approved five
space-related bills March 8, including legislation seeking to modernize
regulations for satellites in non-geostationary orbit (NGSO).
+ The Satellite and Telecommunications Streamlining Act (HR 1338) would
give the FCC defined deadlines for processing satellite license
applications. It would require the FCC to “modernize its rules to encourage
operators to base their operations in the United States,” said House Energy
and Commerce Chair Cathy Rodgers (R-Wash.), “and incentivize operators to
be responsible stewards of space and spectrum in a global marketplace.”
+ The Secure Space Act (HR 675) would prohibit the FCC from granting
satellite licenses to foreign entities the U.S. deems a threat to national
security or domestic supply chains.
+ Launch Communications Act (HR 682) would streamline the process for
accessing certain spectrum for performing commercial spacecraft launches
and reentries.
+ Precision Agriculture Satellite Connectivity Act (HR 1339) would compel
the FCC would to review rule changes that could help promote space-based
communications for the agriculture market.
+ Advanced, Local Emergency Response Telecommunications Parity Act (HR
1353) would facilitate the use of satellites as providers of connectivity
for emergency services in areas hit by natural disasters or otherwise
lacking wireless communications.

AMSAT-INDIA Participates in Science Carnival
To celebrate National Day of India on February 28 one of the biggest
Science Carnival 2023 was organised by Gujarat state - India at prestigious
Science City Ahmedabad during 28th February to 4th March 2023.
AMSAT-INDIA was specially invited to participate in this biggest scientific
exhibition for mass awareness on Amateur Radio & Satellite Communication!
AMSAT-INDIA Regional Coordinator Rajesh Vagadia VU2EXP & team member Sakshi
Vagadia VU3EXP did huge efforts to mass promote AMSAT activities amongst
all sort of visitors which includes young kids, school-college students,
budding engineers, IT Programmers, general public, professionals from
various industries, scientists from renowned organization like ISRO, PRL,
IPR, VSSE, ISR, officers from BSF, Police, Fire dept and citizens from
every walk of life! More than 100,000 visitors were reported and grabbed
the opportunity to visit science carnival 2023 and our Science exhibition
during 5 days.
AMSAT-INDIA stall was spacious & decent sized at 3m x 3m, it was a big
attraction at the center of the Science Exhibition. With well prepared
different informative Banners on AMSAT-INDIA, Various Satellite Activities,
Amateur Radio Satellite chronology, ARISS Student outreach program, ARISS
SSTV event, Question submission for our upcoming ARISS student outreach
program etc was absolutely eye catching from a distance.
For the curious visitors we tried to highlight every aspect of our hobby
and exhibited all sorts of Radio stuff, Documents, QSL Cards, Books, Ham
License, Awards, Project articles, Tracking software, SSTV software, SDR
Software, Cube Satellite models etc to give bit idea of our hobby.
Experiencing various amateur radio gear, satellite antenna & test
instruments were highly appreciated by visiting budding engineers from a
number of colleges at AMSAT-INDIA stall. Some of the stuff we displayed
include; Dual band Arrow-II antenna, dual band Yagi, tape measure antenna,
GP, Telescopic antenna for SDR, Radios includes Icom IC-705 with LiFePO4
battery pack, Kenwood VHF base, half dozen of VHF/UHF HTs, RTL-SDR setup,
LDG ATU, NanoVNA, Morse Key, cw oscillator, Paddle, electronic keyer,
SWR/Power meter, Cable, Connectors etc. It made our task easy to explain
the use of each stuff according to the visitors' query.
We came across various types of queries like how to be a Ham, Procedure to
get license, Types of Amateur Radio satellites, operating modes, setting up
ground station, how to receive ISS SSTV images, how to establish satellite
contact etc. We made a humble attempt to answer & satisfy all of those
queries. We enjoyed a very detailed discussion with students/groups who
already know about Amateur Radio and always need to learn more on Satellite
Communication.
We also highlighted contributions of worldwide AMSAT organizations, IARU,
ARISS, RSGB, ARRL and our ARSI & GIAR. I also mark a note on an author and
my teacher Mr. Nagendra Vijay of popular Gujarati Science magazine named
'Scope' who did tremendous efforts to introduce Ham Radio in Gujarat
(India) 40 years back and still continue to create awareness via it's
leading Science magazine 'Safari', his stall was just after a row.
Our AMSAT-INDIA stall were visited by many well-wisher GIAR Ham friends
including VU2CPV Pravinbhai, VU2JGI Jagdishbhai, VU2MJP Manojbhai, VU2SPF
Bhatnagarji, VU3APY Asheshbhai, VU3VDC Vitthhalbhai, VU3GLY Priyesh, VU3WHO

ISS Dodges Commercial Imaging Satellite
The International Space Station adjusted its orbit March 6 to avoid a close
approach by an imaging satellite operated by Satellogic, the latest
evidence of growing congestion in low Earth orbit.
NASA said in a March 6 blog post that the Progress MS-22 spacecraft docked
to the station fired its thrusters for a little more than six minutes,
raising the station’s orbit to move out of the way of what the agency
called an Earth observation satellite. According to Roscosmos, the
maneuver, lasting 375.8 seconds, changed the station’s velocity by 0.7
meters per second.
NASA spokesperson Sandra Jones told SpaceNews March 7 that the spacecraft
would have approached within about 2.7 kilometers of the station without
the maneuver. She did not identify the satellite involved in the close
approach to the station other than an “Argentine earth observation
satellite launched in 2020.” Other sources said the satellite was NuSat-17,
also called NewSat-17, one of 10 satellites launched in November 2020 by
Satellogic, headquartered in Buenos Aires.
A Satellogic spokesperson said late March 7 it received a conjunction data
message, or CDM, from the 18th Space Defense Squadron, the Space Force unit
that handles space situational awareness activities, about this close
approach.
The orbit of NewSat-17 and the other nine satellites launched in 2020 have
been gradually decaying, and are now crossing the orbital altitude of the
ISS. That is an increasing concern for ISS operations as it and other Earth
observation satellites typically operate in higher sun-synchronous orbits
that will decay if not actively deorbited at the end of the missions.
The March 6 maneuver, NASA said, will not affect upcoming spacecraft going
to and from the station. However, amateurs using the ARISS repeaters will
want to be sure to have updated Keplerian elements that take the new orbit
into account.

Changes to AMSAT-NA TLE Distribution for [date]
Two Line Elements or TLEs, often referred to as Keplerian elements or keps
in the amateur community, are the inputs to the SGP4 standard mathematical
model of spacecraft orbits used by most amateur tracking programs. Weekly
updates are completely adequate for most amateur satellites. TLE bulletin
files are updated Thursday evenings around 2300 UTC, or more frequently if
new high interest satellites are launched. More information may be found at
https://www.amsat.org/keplerian-elements-resources/
{This spot for changes to TLEs when applicable. Can be eliminated or
replaced if none.}
{Do note that our Manual of Style specifies that we ALWAYS use first & last
names, callsign separated by commas, and then the title of the AMSAT
officer, if any. See example below. Same style applies to persons
referenced in story bodies, as well as in attributions.}

Satellite Shorts From All Over
+ NASA and SpaceX are targeting 23:30 UTC Tuesday, March 14, to launch the
company’s 27th commercial resupply mission to the International Space
Station. Liftoff will be from Launch Complex 39A at the NASA’s Kennedy
Space Center in Florida. Launch timing is dependent upon the undocking and
return of NASA’s SpaceX Crew-5. Live launch coverage will air on NASA
Television, the NASA app, and the agency’s website at:
https://www.nasa.gov/live (ANS thanks NASA for the above information)
+ The White House is proposing a $27.2 billion budget for NASA in fiscal
year 2024 that would include increased funding for Artemis and starting
work on a tug to deorbit the International Space Station. The Biden
administration’s budget framework, released March 9, proposed increasing
NASA’s budget by 7% from the nearly $25.4 billion the agency received in
fiscal year 2023, roughly keeping pace with inflation. (ANS thanks
SpaceNews for the above information)
+ China has been dropping hints about its Long March 9 (CZ-9) rocket, a
three-stage super-heavy variant of the Long March family. This launch
vehicle will reportedly be capable of transporting up to 150,000 kg (16.5
tons) to Low Earth Orbit (LEO) and 54,000 kg (59.5 tons) to a trans-lunar
injection. On March 2nd, the China Academy of Launch Vehicle Technology
(CALT) announced (via the Chinese social media platform Weixin) that it had
finished building the first propellant tank for the CZ-9. (ANS thanks
Universe Today for the above information)
+ After a decade in development, JAXA & Mitsubishi Heavy Industries’
medium-lift H3 rocket, an upgraded and lower cost (around $50M vs $90M per
launch) version of their H2-A launch vehicle, finally took off.
Unfortunately, second-stage ignition failed and flight controllers were
forced to terminate the mission. The self-destruct sequence took JAXA’s
ALOS-3 along with it -- a high-resolution optical Earth Observation
satellite which would have had a ground resolution of 0.8 m. (ANS thanks
The Orbital Index for the above information)
+ The Amateur Radio on the International Space Station (ARISS) Program is
seeking U.S.education institutions and organizations to host an Amateur
Radio contact with a crew member on board the ISS in the first half of
