New Satellite Distance Records

IO-117 continues to provide a lot of DX fun for amateur satellite operators. Numerous satellite operators have reported receiving the ARRL’s Worked All States and DX Century Club Satellite awards lately as well as CQ Magazine’s Worked All Zones Satellite award (25 of 40 zones are required for the satellite award). For an example about the distances that can be worked via this satellite in Medium Earth Orbit (MEO), two QSOs got very near the 13,000 km mark recently.

On February 11, 2023, Dave Fisher, KG0D, worked Lucky Bijanki, VU2LBW. The distance between KG0D in CN88kd and VU2LBW in MK82tv is 12,939 km.

Unfortunately for this claim, Hector Martinez Sis, W5CBF, worked Oleg Vakochine, A65BR, on January 29, 2023 at 21:00 UTC. The distance between W5CBF and A65BR is 12,996 km.

Note that only real-time QSOs will be considered for distance records. Under the ARRL’s current interpretation of their award rules, satellite QSOs involving delayed messaging or store-and-forward systems are not valid for WAS, DXCC, or VUCC. Thus, QSOs made over multiple orbits using this method will not be considered for inclusion in the AMSAT Satellite Distance Records archive.

Also please note that the distance calculator at k7fry.com/grid is used to calculate all distances for AMSAT records purposes. This may not provide the most accurate distance under the most recent geodetic datum standards, but it is a consistent reference.

Anyone who wants to claim a distance record via an amateur satellite should check the current list at https://www.amsat.org/satellite-distance-records/ and email n8hm at arrl.net if they complete a new record distance. Audio and/or video of the QSO is encouraged but not required.

Changes to AMSAT-NA TLE Distribution for March 2, 2023

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 week there are no additions or deletions to the weekly AMSAT TLE
distribution.

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.

Quick list of scheduled contacts and events:

Jumeirah College Dubai, Dubai, United Arab Emirates, telebridge via VK4KHZ (***)

The ISS callsign is presently scheduled to be NA1SS
The downlink frequency is presently scheduled to be 145.800 MHz
The scheduled crewmember is Sultan Al Neyadi KI5VTV

Contact is go for: Tue 2023-03-07 08:45:03 UTC 27 deg (***)

The crossband repeater continues to be active. 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.

Comments on making general contacts

I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities.

Typical daily schedule

Wakeup to Workday start= 1.5 hours
Workday start to Workday end=12 hours
Workday end to Sleep= 2 hours
Sleep to wakeup= 8.5 hours

The crew’s usual waking period is 0730 – 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They’re usually free most of the weekend, as well.

SSTV events are not that often. So please check out https://bit.ly/3vKe2LF for the latest information or watch for the ARISS announcements.

And don’t forget that the packet system is active.

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