FrequencyCast ARISSat-1 Video

The UK Tech Podcast, FrequencyCast, has released a short video showing reception in Essex of FM voice and an SSTV image from the amateur radio satellite ARISSat-1.

The 145.950 MHz FM signal was recorded at 1055 UT on November 14, 2011 and was uploaded to support the feature at http://www.essexham.co.uk/arissat

The 6502 based BBC Microcomputer

The 6502 based BBC Microcomputer

The first 6502 based BBC microcomputers were produced on December 1, 1981. They proved popular with radio amateurs who used them for RTTY, Cambridge Packet Radio, SSTV and running the AMSAT-UK software library.

The Cambridge Packet Radio software was popular in the years before the widespread adopton of the AX.25 standard. The free software enabled users to send and receive packet radio direct from the BBC Micros cassette tape interface without needing a seperate modem. Software for other modes required an additional modem interface such as the IGADUMA which was produced by radio amateurs in Hertfordshire. Continue reading

Vega to Launch Amateur Radio Satellites

The inaugural launch of the ESA Vega rocket will carry the amateur radio microsatellite ALMASat-1 and at least six CubeSats.

The satellites will be launched from the ESA spaceport at Kourou in the Caribbean into an elliptical orbit of 1450 by 354 km at an inclination of 71 degrees. They are expected to have a lifetime before re-entry of 4 years.

ESA say the six CubeSats to be launched on Vega in late January 2012 comprise:

Xatcobeo (a collaboration of the University of Vigo and INTA, Spain): a mission to demonstrate software-defined radio and solar panel deployment;
Robusta (University of Montpellier 2, France): a mission to test and evaluate radiation effects (low dose rate) on bipolar transistor electronic components;
e-st@r (Politecnico di Torino, Italy): demonstration of an active 3-axis Attitude Determination and Control system including an inertial measurement unit;
Goliat (University of Bucharest, Romania): imaging of the Earth surface using a digital camera and in-situ measurement of radiation dose and micrometeoroid flux;
PW-Sat (Warsaw University of Technology, Poland): a mission to test a deployable atmospheric drag augmentation device for de-orbiting CubeSats;
MaSat-1 (Budapest University of Technology and Economics): a mission to demonstrate various spacecraft avionics, including a power conditioning system, transceiver and on-board data handling.

ESA indicate that a 7th CubeSat may be delivered in time to be flown.

PW-Sat carries an FM to DSB amateur radio transponder with an FM input on 435.020 MHz and DSB output on 145.900 MHz.

The primary payload on the launch, LARES, will be deployed into an orbit of 1200 km × 1200 km with an inclination of 71 degrees.

Impression of STARS-II in Orbit

The amateur radio satellite STARS-II has been developed by students at Kagawa University and consists of a Mother satellite and Daughter satellite connected by tether.

STARS stands for Space Tethered Autonomous Robotic Satellite. The mission will include formation flight, tether deployment, attitude control and the mother and daughter satellites will take pictures of each other.

It is proposed to fly a 80mW CW beacon and a 800mW AX25 1200bps telemetry downlink. Total mass is 8 kg.

Coordinated frequencies for CW 437.245 MHz (mother) and 437.255 MHz (daughter). FM downlinks 437.405 MHz (mother) and 437.425 MHz (daughter).
