TLEdoctor program to check for preliminary TLE data
by Jarda 06 Aug '19

06 Aug '19

The program can easily detect and fix the TLE preliminary data errors for working in satellite programs after launching the satellite in orbit The original version of the program released before launching Fox-1D works in Windows-7 and higher. Version that works in Windows XP is now added. The program name for Win-XP changes to TLEdoctor. Both programs can be downloaded at http://oscar.ok2gz.eu/fox1d.php 73 Jarda ok2gz --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus

Fw: AO73 Mode change
by Graham Shirville 11 Jun '19

11 Jun '19

Hi folks, AO73/FUNcube is now in amateur mode for the weekend with the transponder on! Please see below for all FUNcube mission info 73s Graham G3VZV and the FUNcube team. ++++++++++++++++++++++++++++++++++ FUNcube frequencies and other details ++++++++++++++++++++++++++++++++++ AO-73 FUNcube-1 The transponder is normally operational only when the satellite is in eclipse, ie the solar panels are NOT being illuminated. During weekends (from pm Fridays UTC to PM Sundays UTC) the transponder is operational 24/7. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. During holidays, eg Christmas, New Year, Easter, etc, the transponder maybe activated for extended periods. Watch AMSAT-BB for announcements which are usually made on Friday evenings (UTC) The nominal transponder frequencies are: Uplink: 435.150 - 435.130 MHz LSB (Inverting) Downlink: 145.950 - 145.970 MHz USB Telemetry Tx: 145.935 MHz BPSK (The passband may be up to 15kHz higher depending on on-board temps. Lower temperatures give higher freqs!) FUNcube-2 (aka FUNcube on UKube) The FUNcube-2 sub-system continues to operate autonomously and, almost continuously, in amateur mode. The transponder is operational and the telemetry downlink is functioning with about 70mW output. The FUNcube-1 Dashboard does not correctly display the telemetry but it does correctly decode the data and uploads it to the FUNcube Data Warehouse from where it can be examined. Most of the real time data channels are operational and these include battery voltages, temperatures and ADCS data coming via the main On Board Computer (OBC). The transponder is interrupted for a few seconds every 2 minutes when the other transmitter sends its CW beacon and, occasionally, for a few seconds when the main OBC reboots (approx seven times each orbit). The nominal transponder frequencies are: Uplink: 435.080 - 435.060 MHz LSB (Inverting) Downlink: 145.930 - 145.950 MHz USB Telemetry Tx: 145.915 MHz BPSK (The passband may be up to 10kHz higher depending on on-board temps. Low temperatures give higher freqs!) EO79 FUNcube-3 Due to power budget constraints the transponder cannot be operational 24/7 and an orbit specific schedule has been developed. The transponder will commence operation 27 minutes after the spacecraft enters sunlight and will stay on for a period of 25 minutes. This schedule may be modified in future months as a result of experience. The nominal transponder frequencies are: Uplink: 435.0723-435.0473 MHz LSB (Inverting) Downlink: 145.946-145.971 MHz USB Further detailed info on EO79 transponder frequencies is at: https://amsat-uk.org/2016/11/10/eo79-funcube-3-transponder-commences-regula… EO88/Nayif-1/FUNcube-5 EO88 is presently operating in autonomous mode. The transponder is operational when the satellite is in eclipse, ie the solar panels are NOT being illuminated. When the transponder is switched off, the telemetry beacon is on full power, when the transponder is on the beacon it is on low power. The transponder frequencies are: Uplink: 435.045 – 435.015 MHz LSB (inverting) Downlink: 145.960-145.990 MHz USB Telemetry Tx: 145.940MHz All FUNcube transponders are sponsored by AMSAT-UK and AMSAT-NL. We are very grateful for the assistance given by Innovative Solution In Space Bv, The Netherlands. _______________________________________________ Sent via AMSAT-BB(a)amsat.org.

Good SAT program
by Vincenzo Mone 03 May '18

03 May '18

Hi folks, I am looking for a good program like Orbitron or the old Satsked that gives me the possibility to keep under the eyes all the satellite and in the mean time has the possibility to track the satellites moving also the rotators and the radio.I was using SatPC interfaced with the rotators with the ERC-M kit and the Kenwood TS-2000x. It is a great program but has the problem that I do not have under my eyes all the satellites and have noticed that if I am visualising in one group and in another group there is a satellite rising I will not be advised. Orbitron is OK as I can have all the satellites under my eyes but I cannot or better I do not know how to interface it with the radio and the Yaesu G-5500 rotators via the ERC-M interface kit. Anybody can point me to the right way? Thanks 73's de Enzo IK8OZV EasyLog 5 BetaTester EasyLog PDA BetaTester WinBollet BetaTester D.C.I.

Zhou Enlai (HA 1) downlink active
by Nico Janssen 02 May '18

02 May '18

The Chinese amateur satellite Zhou Enlai (initially know as Huai'An 1, HA 1) appears to be active on a downlink frequency near 437.650 MHz. Its coordinated downlink frequency for telemetry is 437.350 MHz and for voice 436.950 MHz. For details see: http://www.amsat.org.uk/iaru/ http://space.skyrocket.de/doc_sdat/zhou_enlai.htm This 2U cubesat is object 43156, 2018-008B. Let's see if they can activate its FM repeater and SSTV component. 73, Nico PA0DLO

Each year, ARISS provides tens of thousands of students with opportunities to learn about space technologies and communications through the exploration of Amateur Radio. The program provides learning opportunities by connecting students to astronauts aboard the International Space Station (ISS) through a partnership between NASA, the Radio Amateur Satellite Corporation, the American Radio Relay League, and other Amateur Radio organizations and worldwide space agencies. The program’s goal is to inspire students to pursue interests and careers in science, technology, engineering and mathematics (STEM) and Amateur Radio. A ham recently said, “ARISS shows how Amateur Radio is the most unique hobby/service there is.” Educators overwhelmingly report that student participation in the ARISS program stimulates interest in STEM subjects and in STEM careers. One educator wrote, “It exceeded our expectations--it created a great interest in both amateur radio and in space exploration. Our kids are completely inspired!” Ninety-two percent of educators who have participated in the program have indicated that ARISS provided ideas for encouraging student exploration and participation. An educator even joined the ham ranks, saying, “This chance for our school’s ARISS contact helped me see the great value of the ham world. I just passed my Technician License this weekend and have already signed up to take a General class.” ARISS is looking for organizations that will draw large numbers of participants and integrate the contact into a well-developed, exciting education plan. Students can learn about satellite communications, wireless technology, science research conducted on the ISS, radio science, and any related STEM subject. Students learn to use Amateur Radio to talk directly to an astronaut and ask their STEM-related questions. ARISS will help educational organizations locate Amateur Radio groups who can assist with equipment for this once-in-a-lifetime opportunity for students. The proposal deadline for 2019 contacts is April 30, 2018. Proposal webinars for guidance and getting questions answers will be offered March 29, 2018, at 7 p.m. EDT and April 16, 2018, at 4 p.m. EDT. Advance registration is necessary.
