AMSAT Files Comments in FCC Orbital Debris Mitigation Proceeding

AMSAT believes several of FCC’s proposed rule changes concerning orbital debris would have an extremely detrimental affect on the amateur satellite service.

The AMSAT News Service Reports:

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 affect 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.

An APRS payload from AMSAT INDIA will be flown on the PSLV-C45 mission expected to launch on April 1, 2019 at 03:57 GMT.

On the AMSAT Bulletin Board Nitin VU3TYG writes:

The payload will be powered on approximately over Sweden, Norway, Denmark, Finland, Poland and Moscow. We request stations at these locations to report the first signals on 145.825 MHz from the payload.

We also request the Amateur Radio fraternity worldwide to use the payload and Satgates to feed the traffic. More details about this unique project as well as the prelaunch TLE are available at

It is understood the PSLV-C45 mission will deploy 29 satellites. The 4th stage of the rocket (PS4) will become an orbital platform in a 485 km orbit hosting three payloads:
• Automatic Packet Reporting System (APRS) digipeater from AMSAT INDIA
• Automatic Identification System (AIS) from ISRO
• Advanced Retarding Potential Analyzer for Ionospheric Studies (ARIS) from the Indian Institute of Space Science and Technology (IIST).

Dmitry R4UAB reports cosmonauts on the International Space Station will again be transmitting SSTV images, April 1-2, on 145.800 MHz FM as part of the Inter-MAI-75 experiment.

A Google translation reads:

“Inter-MAI-75” (Education and promotion of space research) – an experiment aimed at combining the efforts of educational universities and radio amateurs in Russia and the United States to develop technology and technical tools that enable students to communicate and collaborate with astronauts and astronauts in the study and development of the management process ISS, as well as to work out various methods of transmission and various types of transmitted information (text, voice and telemetry information, black and white and color photos and video from blasts, etc.), obtained as a result of scientific and educational experiments through the use of amateur radio communications onboard the ISS.

SSTV images will be transmitted at a frequency of 145.800 MHz using a Kenwood TM-D710 transceiver. They are expected to use the PD-120 SSTV format.

Schedule:
• Monday, April 1, 2019 from about 1400 to about 1900 GMT
• Tuesday, April 2, 2019 from about 1400 to about 1900 GMT
