Main body of the satellite has a shape of 10 cm Cube, and its mass will be 1.5 kg. An expanding boom for attitude control and two solar paddles are attached to the main body.
Over 150 students at the Nanyang Technological University in Singapore have worked on the innovative nanosat project VELOX-I.
VELOX-I consists of two satellites: a 3U nano-satellite N-Sat and a 1U pico-satellite P-Sat. N-Sat is developed to be a robust satellite bus for future missions, and P-Sat is an experimental design to carry a scientific payload. During the mission P-Sat will be released by N-Sat.
The VELOX-I mission includes demonstrating high-resolution vision subsystem, testing a MEMS-based attitude determination and control system, verifying intersatellite RF link, and performing a quantum physics experiment.
It is hoped it will launch in 2013, a downlink of 145.980 MHz has been coordinated.

Kibo Robot Arm CubeSat Deployment
Sixteen educational satellites are under construction in Japan. The first should be launched in May 2012 followed by the others over the next two years.
HORYU-2 Structural Thermal Model
The first to launch is the amateur radio satellite HORYU-2 built by students at the Kyushu Institute of Technology (KIT). The launch is on a Japanese H-IIA rocket planned for May 17 at 1639-1642 UT.
The mission aims to take pictures of the Earth using a small CMOS camera SCAMP (Surrey Camera Payload) developed by the University of Surrey, a sister university of KIT. SCAMP takes a 640×480 pixel picture in a JPEG format. From 700 km altitude, one pixel corresponds to 1.6 km.
HORYU-2 will be followed in July by the launch of the HTV3 to the International Space Station (ISS). This will deliver the JEM-Small Satellite Orbital Deployer (J-SSOD) along with the Japanese CubeSats WE-WISH, FITSAT-1 and RAIKO. These CubeSats should be deployed from the ISS in September using the Japanese Experiment Module (JEM) robot arm.
Takushi Tanaka JA6AVG and FITSAT
FITSAT-1, also known as NIWAKA, will use a neodymium magnet for attitude control. It has multiple downlinks, CW on 437.250 MHz, AX.25 on 437.445 MHz and a 4 watt high speed data transmitter on 5840 MHz capable of sending a 640 by 480 VGA JPEG image in 6 seconds.
In addition it carries high power LEDs that will be driven with 100W pulses to produce extremely bright flashes. These, it is hoped, will be observable by the unaided eye or with small binoculars. Both the 5840 MHz and optical downlinks have a high power consumption so it may be that they are only activated over Japan.
In December TSUBAME is planned to be launched on a H-IIA. It aims to have a CW beacon on 437.250 MHz and AX.25 1200/9600bps telemetry on 437.505 MHz.

The International Traffic in Arms Regulations (ITAR) inexplicably applies to amateur radio satellites. It threatens US hams with jail terms or six figure fines if they cooperate with amateurs outside the USA on satellite projects. Cooperation includes talking about or publishing on the web certain information regarding amateur radio satellite systems.
US Department of Defense (DoD) has recommended some US-built satellites and components should be transferred from the US Munitions List (USML) to the Commerce Control List (CCL), allowing greater export flexibility.
Known as the Section 1248 report after the section of the 2010 DoD authorisation bill that commissioned it, the report recommends that authority to classify communications satellites and certain remote sensing satellites, as well as many satellite components, be returned to the president.
The report says:
The review determined that the following items do not contain technologies unique to military applications or critical for maintaining a military edge:
– Communications satellites (COMSATs) that do not contain classified components;
– Remote sensing satellites with performance parameters below (worse than) thresholds identified in Appendix 1 paragraphs (a)(7)(i) – (iv); and
– Systems, subsystems, parts and components associated with these satellites and with performance – parameters below thresholds specified for items remaining on the USML.
The above items no longer meet the definition of a defense article. However, they can provide important military functionality. Although the United States and other space-faring nations have technologies and satellites far more capable than the items identified above, those dual-use technologies can be used by countries with less experience and expertise in space to generate basic, initial military communications, remote sensing assets, and satellite jamming capabilities.
The controls typically applied to dual-use items on the Commerce Control List (CCL) are sufficient to safeguard and monitor the export of the identified items.

Dave Johnson G4DPZ with NRC Sponsor Plaques
Sponsor plaques have now been fitted in the reception to the RSGB National Radio Centre at Bletchley Park.
Dave Johnson G4DPZ is one of a number of individuals and organisations who either gave freely of their time or supplied equipment to make the National Radio Centre the premier exhibition that it is.
AMSAT-UK donated the WiMo X quads for 144 and 430 MHz along with pre amps and polarisation switches for the amateur radio satellite station. They are connected to a Kenwood TS-2000 loaned by Kenwood Electronics.
