ARISS Next Generation Radio System Completes Critical Flight Certification Tests

by

The Interoperable Radio System (IORS), ARISS’ next generation radio system successfully completed a battery of stressful tests required as part of the final certification of the hardware for launch to and operation on the International Space Station.

During the week of July 8, the IORS, consisting of the JVC Kenwood D-710GA Radio and the AMSAT developed Multi-Voltage Power Supply, successfully completed a series of Electro-magnetic Interference (EMI)/Electro-Magnetic Compatibility (EMC) tests to ensure that the ARISS hardware will not interfere with the ISS systems or other payloads. Testing continued into the following week, where the IORS successfully passed power quality and acoustics testing. These tests verified that the ARISS IORS will not introduce harmful signals back into the ISS power system and is quiet enough to meet ISS acoustic requirements. ARISS Hardware Team members Lou McFadin, W5DID and Kerry Banke, N6IZW were at the NASA Johnson Space Centersupporting this two week battery of tests in concert with the NASA test and certification team.

Kerry Banke states, “Since the IORS is being qualified to operate on 120VDC, 28VDC and Russian 28VDC as well as transmitting on VHF or UHF, a lot of test combinations were required to cover all cases. Each input voltage type was also tested at low,medium and high line voltage. Moreover, additional permutations were required to test the IORS under no load, medium load and full load at each voltage level. So it should not be surprising why the tests took two weeks to complete.”

Successful completion of these tests represents a key milestone in preparing the IORS for launch. ARISS can now begin final assembly of the flight safety certification in preparation for launch. ARISS is working towards launch ready status by the end of the year.

About ARISS:

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), the ISS National Lab and 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 public forms. Before and during these radio contacts, students, educators, parents, and communities learn about space, space technologies, and amateur radio. For more information, see www.ariss.org.

AMSAT President Joe Spier, K6WAO, Awarded Russian E.T. Krenkel Medal

by
AMSAT President Joe Spier, K6WAO

AMSAT President and ARRL Life Member Joe Spier, K6WAO, has been awarded the Russian E.T. Krenkel Medal, a prestigious award granted to individuals and organizations for outstanding global contributions to Amateur Radio.

Joe Spier, K6WAO is a long time supporter of Amateur Radio in Space and international cooperation. K6WAO is the President of the Radio Amateur Satellite Corporation (AMSAT). He has also served AMSAT as Executive Vice President, and Vice President, Educational Relations.

He is a long term supporter of Amateur Radio on the International Space Station (ARISS) and scientific, technical, engineering, and mathematics education. Spier is an AMSAT Life Member. He also is a Life Member of American Radio Relay League (ARRL) and the Society of Amateur Radio Astronomers (SARA).

The award’s namesake, Ernst Teodorovich Krenkel, was a radio amateur who, over the years, used the call signs RAEM, U3AA, and UA3AA. Born in Poland, Krenkel was an Arctic explorer who took part in the first Soviet “drifting station,” North Pole-1. He was made a “Hero of the Soviet Union” in 1938 for his exploits.

Krenkel’s son, T.E. Krenkel, is among the four signatories to the award certificate. The younger Krenkel, a professor at the Moscow Technical College of Telecommunication and Informatics, said his father was an avid radio amateur who served as the first chairman of the Central Radio Club in the USSR.

Krenkel’s image appears on postage stamps from the USSR and Russia, and he authored a biography entitled My Callsign is RAEM. In the era when all radio amateurs received QSL cards via Box 88, Moscow, Krenkel was allowed to have his own postal address on his QSLs and was issued the non-standard RAEM call sign.

Diwata-2 Designated Philippines-OSCAR 101 (PO-101)

by

On October 29, 2018, the Diwata-2 microsatellite was launched on a H-IIA launch vehicle from the Tanegashima Space Center, Tanegashima, Japan. Diwata-2 was developed by the University of the Philippines Dillman (UPD) and the Advanced Science and Technology Institute of the Department of Science and Technology (DOST-ASTI) under the PHL-Microsat program (now succeeded by the STAMINA4Space program), and in cooperation with Tohoku University and Hokkaido University.  The project was funded by the Department of Science and Technology (DOST) and monitored by the DOST-Philippine Council for Industry, Energy and Emerging Technology Research and Development (DOST-PCIEERD). The satellite carries an amateur radio payload that has been tested and is now ready for service.

At the request of the STAMINA4Space program, AMSAT hereby designates Diwata-2 as Philippines-OSCAR 101 (PO-101). We congratulate the owners and operators of PO-101, thank them for their contribution to the amateur satellite community, and wish them continued success on this and future projects.

AMSAT Files Comments in FCC Orbital Debris Mitigation Proceeding

by

The Federal Communications Commission has proposed several rules changes related to the amateur satellite service as part of a Notice of Proposed Rulemaking (NPRM) related to the mitigation of orbital debris. AMSAT believes several of these rule changes would have an extremely detrimental effect on the amateur satellite service and AMSAT’s ability to launch and operate new satellites, including AMSAT’s upcoming GOLF satellites.

Today, AMSAT filed comments on the proposed rulemaking. In the comments, AMSAT argues that amateur satellites often have longer mission lifespans than other small satellite missions and that the Commission should take a mission duration of 5 to 10 years into account when determining whether or not an amateur satellite will meet the orbital debris regulations by transferring to a parking orbit or re-entering the atmosphere within 25 years of mission completion. The current practice is to assume a “zero year” mission and to require that amateur satellites either transfer to a parking orbit or re-enter within 25 years following launch.

AMSAT also urged the Commission to consider alternatives to a proposed rule that would restrict satellites in Low Earth Orbit that plan to meet the orbital debris mitigation guidelines through atmospheric re-entry to altitudes of 650 km or less. AMSAT noted that, had this rule been in place, AO-85 and AO-91 would not have been able to be deployed in their current ellipitcal orbits with apogees of approximately 800 km, despite the fact that both of these satellites will re-enter within 25 years due to their low perigees. Additionally, AMSAT noted that current plans for the GOLF-1 satellite are to meet orbital debris mitigation guidelines through atmospheric re-entry by deploying a drag device that will ensure re-entry within 25 years despite deployment at an altitude of above 1,000 km. This proposed rule would prohibit GOLF-1’s deployment at that altitude.

The Commission’s proposed rules would also require that amateur satellite licensees indemnify the government against any claims made against the United States due to the operation of the satellite. AMSAT believes this proposal would end the ability of AMSAT, or any other entity in the United States, to launch and operate amateur satellites and urges the Commission to consider alternatives, such as establishing a fund to pay any such claims, noting that the likelihood of such a claim is low.

For amateur satellites with propulsion, the Commission proposes a rule that would require any command links as well as satellite telemetry be encrypted. While AMSAT understands and agrees that a satellite carrying a propulsion system must have an encrypted command link, the proposal to require all satellite telemetry be encrypted is unnecessary and counter to the spirit of the amateur service. AMSAT notes that open access to telemetry is expected of amateur satellites and is critical to the educational component of amateur radio satellites.

Finally, AMSAT proposes that the Commission exempt amateur space stations co-located on other spacecraft from the orbital debris mitigation regulations, including any indemnification rule. Noting that AMSAT has pursued opportunities to fly a payload as a rideshare aboard government or commercial satellites, AMSAT argues that, as the satellite’s owner will need to meet orbital debris mitigation requirements to obtain the license in the primary mission’s service, requiring the amateur licensee to meet the orbital debris mitigation requirements as well is redundant. AMSAT proposes that Part 97 be amended to state that amateur space stations co-located on spacecraft with space stations authorized under Part 25 of the Commission’s regulations (for commercial spacecraft) or by the National Telecommunications and Information Administration (NTIA) (for government spacecraft) are exempt from these regulations.
