Changes to AMSAT TLE Distribution for October 10, 2025

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 daily in the first hour of the UTC day. New bulletin files will be posted immediately after reliable elements become available for new amateur satellites. More information may be found at https://www.amsat.org/keplerian-elements-resources/.

The following satellite has been added to this week’s AMSAT TLE distribution:

CSS (TIANHE-1) NORAD Cat ID: 48274 Chinese space station, possible ham gear aboard

We recognize that the entire space station is referred to as “Tiangong”, but use the same identifier as the US Space Force for consistency with other sources of orbital information.

ARISS News

Amateurs and others around the world may listen in on contacts between amateurs operating in schools and allowing students to interact with astronauts and cosmonauts aboard the International Space Station. The downlink frequency on which to listen is 145.800 MHz worldwide.

Scheduled Contacts

1st Radford Semele Scout Group, Radford Semele, United Kingdom, Direct via GB4RSS 

The ISS callsign is presently scheduled to be NA1SS
The downlink frequency is presently scheduled to be 145.800 MHz
The scheduled crewmember is Jonathan (Jonny) Kim KJ5HKP
The ARISS mentor is MØXTD

Contact is go for: Sat 2025-10-18 08:12:55 UTC 81 deg (test pass with color bars)
Contact is go for: Sat 2025-10-18 09:49:40 UTC 43 deg (actual school event pass)

Many times a school may make a last minute decision to do a Livestream or run into a last minute glitch requiring a change of the URL but we at ARISS may not get the URL in time for publication.  You can always check https://live.ariss.org/ to see if a school is Livestreaming.

As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol.

The crossband repeater continues to be active (145.990 MHz up {PL 67} & 437.800 MHz down),  If any crewmember is so inclined, all they have to do is pick up the microphone, raise the volume up, and talk on the crossband repeater. So give a listen, you just never know.

Note, all times are approximate. It is recommended that you do your own orbital prediction or start listening about 10 minutes before the listed time.

The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html

The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html

AMSAT Ambassador Activities

AMSAT Ambassadors provide presentations, demonstrate communicating through amateur satellites, and host information tables at club meetings, hamfests, conventions, maker faires, and other events.

AMSAT Ambassador Clint Bradford, K6LCS, says,

“Think a 75-minute presentation on “working the easy satellites” would be appropriate for your club or event? Let me know by emailing me at k6lcsclint (at) gmail (dot) com or calling me at 909-999-SATS (7287)!”

Clint has NEVER given the exact same show twice: EACH of the 150+ presentations so far has been customized/tailored to their audiences.

Scheduled Events

43rd Annual AMSAT Space Symposium & Annual General Meeting – October 16 thru 19, 2025
Holiday Inn & Suites Phoenix Airport North
1515 North 44th Street
Phoenix, Arizona 85008

Satellite Shorts from All Over

+ October 8, 2025 was the 10th anniversary of the launch of AMSAT’s first Fox-1 satellite, AO-85. Although it suffered from a slightly deaf receiver, AO-85 provided amateur service for four years before succumbing to battery failure, supporting thousands of QSOs. Additionally, the satellite returned 6,411,349 frames of telemetry over its lifetime, including experimental data for Vanderbilt University.

+ ARISS’s SSTV Series 29 highlighting World Space Week concluded last week with over 3,200 people submitting more than 8,000 image decodes so far. To receive a digital certificate, submit your decodes by 23:59 UTC on Sunday, October 12th to https://ariss-usa.org/ARISS_SSTV/ (Thanks to ARISS)

+ A rumor circulated that CAMSAT’s CAS-11 satellite would launch yesterday on the Gravity-1 rocket from a sea launch platform off the coast of Haiyang. Although the launch was successful and the orbital parameters and launch information match the IARU filing for CAS-11, it appears that the satellite was not on board.
