Slow Scan TV (SSTV) images in Scottie 1 format will be transmitted from the SPROUT satellite every Sunday (Japanese Standard Time) on 437.600 MHz FM (+/- 9 kHz Doppler shift). The Digitalker will also be active.

SPROUT, a 20 x 20 x 22 cm amateur radio nano-satellite with a mass of 7.1 kg, launched successfully with the L-band (1236.5 MHz/1257.5 MHz/1278.5 MHz) Synthetic Aperture Radar (SAR) satellite ALOS-2 on May 24, 2014 at 0305 UT. SPROUT is in a 654 km, 97.9 degree inclination Sun Synchronous Orbit (SSO).

SPROUT (Space Research On Unique Technology) was built by students from Nihon University and its objectives are:

1. Operation of satellite by radio amateurs.

A FM Digitalker will enable the satellite to speak to amateurs around the world.

The Voice Message Box will record transmissions from radio amateurs and play them back.

Pre-loaded images from the Message Gallery can be transmitted using Slow Scan TV (SSTV).

Pictures of the Earth can be transmitted by SSTV and radio amateurs can receive it using free software such as MMSSTV. As part of the Earth mapping project the team ask radio amateurs to contribute pictures they have received from the satellite for display on the SPROUT website.

The satellite also has a packet radio Digipeater and Text Message Box function.

SPROUT in orbit2. Demonstration of the deployment of the combined membrane structure and verification of the design method of the structure SPROUT has a triangular membrane supported by two tubes like framework. They are folded and stored in the satellite before the launch. After the launch, the nitrogen gas is injected into the tubes in space, and they extend, so that the membrane deploys (called “combined membrane structure”).

3. Demonstration of attitude determination and control of a nanosatellite using the sun sensors, gyros, geomagnetic sensor and magnetic torquers.

15-year-old radio ham receives ISS Apollo-Soyuz SSTV Award

ISS SSTV Apollo-Soyuz Award #0289 received by Sakshi Vagadia VU3EXP

ISS SSTV Apollo-Soyuz Award #0289 received by Sakshi Vagadia VU3EXP

Rajesh Vagadia VU2EXP reports that he and his15 year old daughter, Sakshi Vagadia VU3EXP, have each received ISS Apollo-Soyuz SSTV Awards for their reception of Slow Scan Television images transmitted using amateur radio from the International Space Station (ISS).

These special transmissions from the ISS during July 18-19, 2015 were made to commemorate the 40th anniversary of the Apollo-Soyuz mission, which was the first joint collaboration in space between the United States and the Soviet Union. The ARISS organisation has issued a special limited edition diploma to award those who received one of the SSTV images.

Rajesh writes: After getting ticket [amateur radio licence] few months back, It was first successful attempt by Sakshi VU3EXP to receive SSTV Image from International Space Station and get such memorable & precious Wallpaper (award). She received ISS SSTV image on July 18, 2015 @ 19:36:44 (UTC).

My ISS SSTV Image was received on July 19 @ 05:24:27 (UTC). It was my 5th successful attempt.

I highly appreciate ARISS International, Russian Cosmonauts, various Radio Clubs and ARISS SSTV Award Managers (incl. SQ3OOK) joint efforts to give such wonderful opportunity to we Ham community.

Students at Sree Narayana Trust Higher Secondary School returned to the classroom during their holidays to receive amateur radio Slow Scan Television from the International Space Station.

The special ISS transmissions were made in July to commemorate the 40th anniversary of the Apollo-Soyuz mission.

The Deccan Chronicle newspaper reports that with the support of their teachers the students were able to decode the SSTV images on a frequency of 145.800 MHz FM.

The school has an amateur radio club, callsign VU2SQL, and the Principal is licenced radio amateur U.Jayan VU2JYU.

ISS SSTV July 18-19 on 145.800 MHz FM

ARISS SSTV images will be transmitted this weekend from the amateur radio station in the ISS Russian Service Module to commemorate the 40th Anniversary of the Apollo-Soyuz Mission.

40 years ago this week, the historic joint Apollo-Soyuz mission was conducted.  Apollo-Soyuz (or Soyuz-Apollo in Russia) represented the first joint USA-Soviet mission and set the stage for follow-on Russia-USA space collaboration on the Space Shuttle, Mir Space Station and the International Space Station.

The Soyuz and Apollo vehicles were docked from July 17-19, 1975, during which time joint experiments and activities were accomplished with the 3 USA astronauts and 2 Soviet Cosmonauts on-board.  Apollo-Soyuz was the final mission of the Apollo program and the last USA human spaceflight mission until the first space shuttle mission in 1981.

To commemorate the 40th anniversary of this historic international event, the ARISS team has developed a series of 12 Slow Scan Television (SSTV) images that will be sent down for reception by schools, educational organizations and ham radio operators, worldwide.  The SSTV images are planned to start sometime Saturday morning, July 18 and run through Sunday July 19.  These dates are tentative and are subject to change.  The SSTV images can be received on 145.800 MHz FM and displayed using several different SSTV computer programs that are available on the internet.

We encourage you to submit your best received SSTV images to:
http://spaceflightsoftware.com/ARISS_SSTV/submit.php

The ARISS SSTV image gallery will post the best SSTV images received from this event at:
http://spaceflightsoftware.com/ARISS_SSTV/index.php

Also, as a special treat, on Saturday July 18 the ISS Cosmonauts will take time out to conduct an ARISS contact with students attending the Moon Day/Frontiers of Flight Museum event in Dallas Texas.  This Russian Cosmonaut-USA Student contact is planned to start around 16:55 UTC through the W6SRJ ground station located in Santa Rosa, California.  ARISS will use the 145.800 MHz FM voice frequency downlink (same as the SSTV downlink) for the Moon Day contact.

For more information on ARISS, please go to our web site http://www.ariss.org/

The ARISS international team would like to thank our ARISS-Russia colleague, Sergey Samburov, RV3DR, for his leadership on this historic commemoration.
