Guatemala’s first satellite, a small CubeSat called QUETZAL-1, was deployed from the International Space Station (ISS) on Tuesday, April 28, 2020.

Its primary mission is to test a sensor for remote data acquisition for natural resource management, which could be used to monitor water quality in inland water bodies.

The satellite is part of the Japanese Kibo cubesat program, a product of the cooperation between, among others, the United Nations Office for Outer Space Affairs (UNOOSA), Universidad del Valle de Guatemala (UVG), and more institutions. The operational frequencies were chosen through cooperation from Guatemalan radio amateurs and the International Amateur Radio Union (IARU).

Downlink 4800 bps GMSK on 437.200 MHz.

The Quetzal-1 project team director is Guatemalan engineer José Bagur, TG8JAV, a graduate from mechatronics engineering at Universidad Del Valle.

DOAAF-85 (RS-44) amateur radio transponder activated

DOSAAF-85 / RS-44

The amateur radio linear transponder (SSB/CW) payload on the Russian satellite DOSAAF-85 (RS-44) has been activated.

Dmitry Pashkov R4UAB reports:

DOSAAF-85 / RS-44 under construction

DOSAAF-85 is a small scientific satellite created by specialists of the company Information Satellite Systems (ISS) Reshetnev and students of the Siberian State Aerospace University (SibSAU) Krasnoyarsk.

The satellite is named after the 85th anniversary of the Voluntary Society for the Assistance to the Army, Aviation and Navy, the organization responsible for the military training of Soviet youth.

The DOSAAF-85 satellite is designed to provide amateur radio communications, as well as to develop promising technologies. This is the third satellite that was created by specialists of ISS-Reshetnev and is based on the Yubileyniy platform, which features a hexagonal prism structure with body mounted solar cells.

The satellite was launched into orbit on December 26, 2019 from the Plesetsk Cosmodrome and is in an elliptical orbit with a perigee of 1175 km, an apogee of 1511 km and an inclination of 82.5 degrees.

Transmitter power: 5 watts
Beacon: 435.605 MHz – transmits CW call sign RS44

Inverting transponder:
Earth-to-Space: 145.965 MHz +/- 30 kHz
Space-to-Earth: 435.640 MHz +/- 30 kHz
