SPROUT SSTV and Digitalker Active Every Sunday – AMSAT-UK

AMSAT-UK Announces SSTV Activity Every Sunday

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

— 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.
