ARRL Comments in Orbital Debris Mitigation Proceeding 10/13/2020
In comments to the FCC, ARRL targeted two specific areas of concern regarding a Further Notice of Proposed Rulemaking (FNPRM) in IB Docket 18-313 — mitigation of orbital debris in the new space age. In an earlier phase of the proceeding, ARRL filed comments and met with FCC staff to discuss the proposed rules. In comments filed on October 9, ARRL focused on the areas of indemnification and maneuverability/propulsion. Indemnification places the liability for any possible damage from a satellite on an individual or entity. ARRL reiterated its assertion that, as a practical matter, an indemnification requirement “would seriously impair the ability of amateur and university experimenters to launch and operate satellites under US auspices” due to the potential liability and high insurance cost.

PREDICT-2.2.7 for Linux, Unix, Android, and Raspberry Pi Platforms
John Maglicane, KD2BD, has announced the release of PREDICT version 2.2.7, an Open Source satellite tracking / orbital prediction application for Linux and Unix computing environments, including PCs, laptops, and Raspberry PIs.
New in this release is a version of PREDICT that operates on Android platforms under a Termux environment. Now you can carry your smartphone in your shirt pocket while voice announcements made by PREDICT’s “vocalizer” tell you where to locate the ISS, Hubble, or other visible satellites in the night sky! There’s even an alarm to alert the observer when the spacecraft enters into eclipse or into sunlight.
Android screenshots are available here:
The Linux/Unix version of PREDICT-2.2.7 is available here: https://www.qsl.net/kd2bd/predict-2.2.7.tar.gz
And the Android/Termux release is available here: https://www.qsl.net/kd2bd/predict-2.2.7-termux.tar.gz
Both versions are source code releases. An included “configure” script will configure and compile PREDICT and its associated utilities for your specific platform while you wait.
Termux is an Android terminal emulator and Linux environment application that is available at no cost through Google Play. Further details are available at: https://termux.com/
Further details on PREDICT are available at: https://www.qsl.net/kd2bd/predict.html
Stay safe, stay well, and Happy Tracking! 73 de John, KD2BD

Upcoming Satellite Operations
Jerome, F4DXV, is plans to operate from a 1500 meter summit in JN15jo on Monday, 19 October. He will be on RS-44 beginning at 2000utc specifically for North America. The footprint covers much of eastern NA. This is a difficult operation after dark and Jerome hopes that many will take advantage of the opportunity to work this very rare grid. RS-44 will be around 1430km.
DN13/23 and DN22: @KI7UNJ, 10/16 – 10/19: No pass list, just follow Twitter, BEACON APRS KI7UNJ-9 KI7UNJ-IOS
16th DN13/23 Line
19th DN13/23 Line
KQ2RP is heading to FN44/54 again. Will be on FM birds from FN54 with occasional FN44/54 line. FN53 possible. Oct 11-16th. Logging as KQ2RP/1.
EL Grids, @N1PEB 10/10 -10-14: 10/10 EL95 Key Largo, 10/11 EL94 Key West, 10/12 EL84 Dry Tortuga, 10/13 EL94 Key West, 10/14 TBD
From TI2BSH: October 16, 2020 I will be working in EK71 and will go out on the satellites:
AO-91 at 04: 22z,05:57z, 16:38z
SO-50 at 04: 48z, 15:16z
If you hear me and want that grid call in international phonetic code. 73s
Major Roves: DL88: Ron (@AD0DX) and Doug (@N6UA) are making another run at the elusive DL88 in Big Bend National Park, TX. As we know they tried this grid back in March, and due to the mud couldn’t get to the grid, so never ones to quit, off they go again. Today the tentative date is Sunday, October 25, 2020. They will be using the K5Z call sign. More information is available at the K5Z QRZ Page.

Satellite Shorts From All Over
+ NASA will provide live coverage of the return to Earth for agency astronaut Chris Cassidy, KF5KDR, and two Russian cosmonauts Wednesday, Oct. 21, after six months aboard the International Space Station. Cassidy, the Expedition 63 commander, and cosmonauts Anatoly Ivanishin and Ivan Vagner of Roscosmos, will close the hatch to their Soyuz MS-16 spacecraft at 20:10 UTC Wednesday. Their Soyuz will undock at 23:32z. A parachute-assisted landing is set for 02:55z on Oct. 22 on the steppe of Kazakhstan. Complete coverage of the return will be available on NASA TV and the agency’s website, https://www.nasa.gov/nasalive (ANS thanks NASA for the above information)
+ Joe Werth, KE9AJ Tweets about a new distance record set for AO-7 Mode A: “Amazing QSO with Olivier, @F5RRO on AO-7 MODE A. Breaking a 40 year old AMSAT distance record at 6,879 km. Olivier used a MA5B Yagi and I used my Moxon….. Thanks Olivier!” The path map may be seen at: https://bit.ly/2SUSeJM (ANS thanks Joe Werth, KE9AJ for passing along the above information)
+ GNU Radio Project (@gnuradio) tweeted at 3:52 PM on Tue, Oct 13, 2020: Wylie Standage-Beier’s @thewyliestcoyot workshop on Writing GNU Radio Blocks is up on YouTube! A hands on intro to blocks, flowgraphs, and systems from simple Python simulation of a phase shift keyed signal in white noise to a functioning communications system.

+ OSIRIS-REx, which launched in 2016 and has been orbiting the asteroid Bennu in microgravity since 2018, is going to try its first Touch And Go (TAG) maneuver next week. This maneuver involves autonomously descending toward the asteroid with the craft’s sample arm extended, briefly making contact, using nitrogen gas to blow loose material in to a sample collection head, and returning to orbit. The pristine sample should arrive back on Earth in September 2023.

+ Blue Origin’s reusable suborbital New Shepard flew on October 13 for the first time since December 2019, completing its 13th flight, and seventh reuse for this booster. The mission successfully carried several NASA experiments, including a “microgravity LilyPond”—-a hydroponic chamber for growing edible aquatic plants in space—-and a system for precise planetary landing that uses both terrain relative navigation (for high altitude use, soon to be used for landing by Mars 2020) and LiDAR (for final propulsive landing), with a planned application to upcoming lunar landing missions.

+ Soyuz crew docks with International Space Station: In a mission marking the end of an era, NASA astronaut and former virus hunter Kate Rubins, using NASA’s last currently contracted seat on a Russian Soyuz spacecraft, rocketed into orbit Wednesday with two cosmonaut crewmates on a record-setting flight to the International Space Station. Celebrating her 42nd birthday, Rubins’ launch came just two weeks before 20th anniversary of the arrival of the station’s first crew on Nov. 2, 2000. Since then, the lab complex has been continuously staffed by rotating crews, or expeditions, of American, Russian, Japanese, European and Canadian fliers along with a handful of space tourists.

+ Oxygen supply fails on Russian segment of ISS, crew not in danger (Oct 15, 2020) The oxygen supply system has failed in a module on the Russian segment of the International Space Station (ISS) but the crew is in no danger, Russian space agency Roscosmos said Thursday. The oxygen supply system on the Zvezda module on the orbital lab failed late on Wednesday but a second system on the American segment is operating normally, a Roscosmos spokesperson told AFP. “Nothing threatens the security of the crew and the ISS,” said the spokesperson, adding this repair work to fix the issue would be carried out on Thursday. The issue arose after three new crew -two Russian cosmonauts and an American astronaut -reached the ISS on Wednesday to bring the number of current crew on board to six.

Tips for the New Satellite Operator
This is the first of a what I hope to be a monthly New Satellite Operators Corner. I will offer AMSAT New Operator tips and links to AMSAT resources for new operators and posts from various interest groups where useful info is published. This weeks tip comes from Rick, WA6NDR via [email protected]. I hope you find this as useful as I have. Jack, KD4IZ, Editor, AMSAT News Service.
Tip of the month: TH-D74mailto:[email protected] A ISS APRS settings From: Rick WA6NDR “I was able to make an ISS APRS contact today with just the TH-D74A and an Arrow antenna (details at the end). I started with a video from Don W6GPS and documented what I ended up doing including minor changes. Change the call sign and email address to yours. “Personal preference” settings are optional. The reasoning behind most of the settings is given in Don’s video. I am using TH-D74A firmware v1.10 (with v1.11 released 8/26/2020 but not seeming worth the installation time).”
