ISS AMATEUR RADIO CUBESAT DEPLOYMENT POSTPONED

ISS Amateur Radio CubeSat deployment postponed

JAXA have announced that the deployment of five CubeSats from the International Space Station (ISS) planned for September 10 has been postponed due to an additional EVA taking place September 5. A new deployment date has not yet been announced.
Four of the CubeSats carry Amateur Radio payloads, they are F-1, FITSAT-1, WE-WISH and TechEdSat.
The small satellites, just 10cm cubed, were transported to the ISS in the HTV-3 cargo vessel that blasted off on an H-IIB rocket from the Tanegashima Space Center on Saturday, July 21 at 02:06 UT.
They arrived at the ISS on July 27 and were unloaded by the Expedition 32 crew.
The CubeSats are mounted in a JEM-Small Satellite Orbital Deployer (J-SSOD).  In one pod are FITSAT-1, TechEdSat and F-1 and in the second pod is WeWish and a scientific 2U CubeSat RAIKO. Japanese astronaut Akihiko Hoshide KE5DNI will use the ISS Kibo robot arm to deploy the pods as demonstrated in this video.

Watch the planned deployment of the CubeSats from the ISS

The CubeSat frequencies are:
F-1

o Rechargeable battery, operates in dark and sunlight
o Output power: max 1.0W, half-wave dipole antenna
o AFSK 1200bps, half duplex, one AX.25 packet every 60 seconds

FITSAT-1

Este texto, sobre el conocido y esperado CUBESAT, lo recibí de Alberto - LU1DZ:

                                  http://i46.tinypic.com/20ifmf.jpg

                      


Un proyecto originario de Japon incluye la puesta en orbita de un pequeño satelite destinado al estudio de las comunicaciones opticas entre estaciones de navegacion espacial.
Se trata de un CUBESAT denominado FITSAT-1 (NIWAKA)  http://www.fit.ac.jp/~tanaka/fitsat.shtml  que utilizando la tecnica de LEDs emitira señales luminosas pulsantes de 200W en Codigo Morse las que se podrian visualizar durante el periodo nocturno.
El Profesor Takushi Tanaka  http://www.fit.ac.jp/~tanaka/ director del proyecto, remarca que sera posible observar las señales de Morse a simple vista sin necesidad de ninguna ayuda y que una vez en orbita el NIWAKA navegara entre los 51 6 ° de latitud Sur y los 51 6° de latitud Norte.
El FITSAT-1 y la estacion terrena utilizando telescopios especiales llevaran a cabo experimentos de comunicacion en Morse de alta velocidad entre ambos puntos con 3 minutos de duracion.
Asi mismo se efectuara una experiencia de comunicaciones en 5,8 GHz y llevara un beacon de 430 MHz. de CW comenzando en Morse internacional con HI y una serie de 18 parametros de medicion y tambien emitira en Packet AX25 a 1200 Baudios.

JAMBOREE ON THE AIR - KF5AQG IS PLANNING TO BE ON THE AIR FROM THE INTERNATIONAL SPACE STATION AS NA1SS



If you are planning on participating in this weekend’s Jamboree On the Air (JOTA), take note: Astronaut Mike Fossum, KF5AQG, is planning to participate in JOTA from the International Space Station, using the call sign NA1SS. According to the AMSAT website, Fossum’s schedule is somewhat flexible on the weekends, but he will not be available for every pass. The typical crew work periods are 0800-1930 UTC, but they are sometimes available a bit later. When available, Fossum will be operating on the standard ISS frequencies. In the US and elsewhere in IARU Regions 2 and 3, the uplink is 144.49 MHz. In Region 1, the uplink is 145.200 MHz. The worldwide downlink for NA1SS is 145.800 MHz.
