Dear all The INSPIRE-Sat 7 satellite is scheduled to be launched on the SpaceX Transporter 7 mission on 11 April 2023 at 06:48 UTC . The INSPIRE-Sat 7 satellite is a university project carried out by the University of Versailles Saint-Quentin en Yvelines (France) on behalf of LATMOS (UVSQ, Sorbonne University, Université Paris Saclay, CNRS). This satellite is a demonstrator for experimenting new technologies with a strong involvement of students. This satellite allows the experimentation of miniaturized remote sensing sensors that could be used for multi-point observation of essential climate variables (ECV) and the ionosphere. INSPIRE-Sat 7 carries : - *A 435.200 MHz telemetry channel with BPSK mode - GR3UH 9k6* - An FM transponder with an uplink of 145.830 MHz and a downlink of 435.200 MHz. The FM transponder is expected to be active at least twice a month, depending on the satellite power budget. - The SPINO card that will be activated for experimentation To receive the telemetry, a software has been developed: *KissTool* . It is available for Windows & Linux: Linux: https://site.amsat-f.org/download/118791/?tmstv=1680945385 Windows : https://site.amsat-f.org/download/118784/?tmstv=1680945385 The user manual is available in French ( https://site.amsat-f.org/josast-kisstool/ ) and English ( https://code.electrolab.fr/xtof/josast/-/blob/27-new-application-for-spino/… <https://code.electrolab.fr/xtof/josast/-/blob/27-new-application-for-spino/…> ) 73's Christophe

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. All dates and times listed follow International Standard ISO 8601 date and time format YYYY-MM-DD HH:MM:SS The complete schedule page has been updated as of 2023-04-08 02:30 UTC. (***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-04-08 02:30 UTC. (***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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://www.ariss.org/ 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. 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 ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.

Re: Geo-locating stations from amateurs satellites
by Nico Janssen 05 Apr '23

I don't remember those experiments. But it is not as complicated as it may seem. This is used routinely by satellites carrying SAR equipment. Of course you have to start with accurate, up-to-date TLEs for the involved satellite. Then you measure the doppler curve of the received signal. You subtract the doppler curve that is caused by the passage of the satellite of your receive location, which can be calculated from the satellite TLE. The result will be the doppler curve that is caused by the passage of the satellite of the transmitter location. The combination of that doppler curve and the TLE can then be used to calculate the transmitter's geographical location. For accurate results the frequency of the transmitter, the receiver and the satellite equipment must be very stable. 73, Nico PA0DLO On 05-04-2023 05:30, Ashhar Farhan via AMSAT-BB wrote: > I do remember some experiments in the 1980s AMSAT newsletter of > attempts at using doppler to geo-locate ground stations.

ARISS News Release No.23-14 Dave Jordan, AA4KN ARISS PR aa4kn(a)amsat.org FORIMMEDIATE RELEASE ARISSContact is Scheduled with Students at Collège Saint-Anatoile, Salins-Les-Bains, France April4, 2023—Amateur Radio on the International Space Station (ARISS) has receivedschedule confirmation for an ARISS radio contact between an astronaut aboardthe International Space Station (ISS) and students at the CollègeSaint-Anatoile, located in Salins-Les-Bains, France. ARISS conducts 60-80 of these special amateurradio contacts each year between students around the globe and crew memberswith ham radio licenses aboard the ISS. Saint Anatoile secondary school is a French private catholicschool located in a rural area in the department of Jura (258,000 population),Burgundy, Franche Comté region. In conjunction with hosting this ARISS contact,the school has developed a 2-year "ARISScontact" project to provide students a real opportunity to discover and understandan environment that is unknown to most of them. The objectives of the projectare to deepen the scientific and linguistic knowledge of the students throughworkshops, and various STEM projects incorporated in their curriculum. All students participated in the project (about 100pupils aged 11 to 14). Supporting this contact are members of the amateur radioclub (F6KSD) and radio amateurs of the AssocitionRéseau des Emetteurs Français (R.E.F.25) who held workshops for students in grades6 and 9. These workshops covered topics that included: an introduction toamateur radio, Morse code, Q code, radio directional-finding, rules ofcommunicating on amateur satellites (using satellite QO-100), orbital mechanics,wave propagation, and much more. This will be a telebridge Contact via Amateur Radio allowing students to ask theirquestions of Astronaut Steve Bowen, amateur radio call sign KI5BKB. Thedownlink frequency for this contact is 145.800 MHZ and may be heard bylisteners that are within the ISS-footprint that also encompasses thetelebridge station. The ARISS amateur radio ground station(telebridge station) for this contact is in Aartselaar, Belgium. The amateurradio volunteer team at the ground station will use the callsign ON4ISS, to establishand maintain the ISS connection. TheARISS radio contact is scheduled for April 7, 2023 at 4:27 pm CEST (France) (14:27:26 UTC,10:27 am EDT, 9:27 am CDT, 8:27 am MST,7:27 am PDT). The public is invitedto watch the live stream at: https://www.youtube.com/embed/live_stream?channel=UCy6st8UemV-88B0PbRlT5sw or the school Youtube channel at https://www.youtube.com/@technofg/streams _______________________________ Astime allows, students will ask these questions: 1.Can the effects of global warming be seen from the Space Station? 2.Does weightlessness change the way you breathe? 3.Do you plant seeds in order to have vegetables and eat them? 4.Do you still have the notion of time inside the ISS? 5.What did you like the most when you first entered the ISS? 6.Why did you want to become an astronaut? 7.How is it possible to sleep in the space station with weightlessness? 8.Have you discovered anything unusual or strange during your last missions? 9.How can the Space Station supply itself with electricity? 10.How do you feel to be one of the few people to go into space? 11.What do you do with your waste? 12.What do you do if someone gets hurt? 13.What is the interest of weightlessness in your research? 14.What constraints do you encounter when you return to Earth in order to regain anormal life? 15.How long is the air reserve of the spacesuits? 16.How do you cook in space? 17.How did you feel during the take-off of the shuttle? 18.Is it hard to walk when you come back on Earth? 19.What is the best activity you have done in space so far? 20.How do you feel weightlessness now, as you are talking to us?

(***) Here you will find a listing of all scheduled school contacts, and questions, other ISS related websites, IRLP and Echolink websites, and instructions for any contact that may be streamed live. https://www.amsat.org/amsat/ariss/news/arissnews.rtf https://www.amsat.org/amsat/ariss/news/arissnews.txt The successful school list has been updated as of 2023-04-01 03:00 UTC. https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### 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://www.ariss.org/ 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. 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 ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general.
