LunART- Lunar Amateur Radio Transponder

LunART- Lunar Amateur Radio Transponder

proposal by radio amateurs from AMSAT-DL for LunART (Lunar Amateur Radio Transponder): a Communications Platform on the Large European Lander to support communication and payload experiments.

Peter Gülzow DB2OS and Matthias Bopp DD1US say a LunART Communications Platform on the Large European Lander will support direct communication with earth through amateur radio frequencies in the microwave bands, support University and Student Payloads with direct access to their experiments, allow Radio Science for a huge community of radio amateur operators and scientists worldwide. It would also provide an important back-up communication capability and capacity during emergency or when ESA network is busy, for example during non-critical times.

LO-94 Amateur Radio in Lunar Orbit

LO-94 Amateur Radio in Lunar Orbit

article about the spacecraft Longjiang-2 / Lunar-OSCAR 94 (LO-94), built by students at the Harbin Institute of Technology, that carried the first Amateur Radio communication system to operate in lunar orbit.

As a part of China’s Chang’e-4 lunar far side mission, two lunar microsatellites for low frequency radio astronomy, amateur radio and education, Longjiang-1 and Longjiang-2, were launched as secondary payloads on 20 May 2018 together with the Queqiao L2 relay satellite.

On 25 May, 2018, Longjiang-2 successfully inserted itself into a lunar elliptical orbit of 357 km × 13,704 km, and became the smallest spacecraft which entered lunar orbit with its own propulsion system. The satellite carried the first amateur radio communication system operating in lunar orbit, which is a VHF/UHF software defined radio (SDR) designed for operation with small ground stations.

This article describes and evaluates the design of the VHF/UHF radio and the waveforms used. Flight results of the VHF/UHF radio are also presented, including operation of the radio, performance analysis of downlink signals and the first lunar orbit UHF very-long-baseline interferometry (VLBI) experiment.

ISS Slow Scan TV for 45th Apollo-Soyuz anniversary

Apollo-Soyuz mission.

Apollo–Soyuz was the first international space mission, carried out jointly by the United States and the Soviet Union in mid-July 1975 and ESA Education say the anniversary will be marked by SSTV transmissions from the ISS.

ESA promote amateur radio in ISS SSTV video

ESA promote amateur radio in ISS SSTV video

The ESA space agency has released a new video ‘How to get pictures from the International Space Station via Amateur Radio’.

Did you know that astronauts on the International Space Station send pictures from space to ground over amateur radio that you yourself can get at home using your computer? ESA show you how to get them, step by step.

The video features radio amateur David Honess 2E0XDO (ex-M6DNT).

DIY Weather Satellite Ground Station

Sasha M6IOR and Sophie M6NYX have made available a Guide for the reception of NOAA satellite images using software defined radio on Windows or MacOS.

The guide suggests a few ways to receive an Automatic Picture Transmission (APT) from active National Oceanic and Atmospheric Administration (NOAA) satellites in the 137 MHz band.
