Four CubeSats carrying amateur radio payloads will be deployed from the International Space Station (ISS) by the JEM Small Satellite Orbital Deployer (J-SSOD). Three of them, Pico Dragon, ArduSat-1 and ArduSat-2 will be deployed on Tuesday, November 19, and the fourth Cubesat, TechEdSat-3p, will be deployed Wednesday.

The CubeSats:
Pico Dragon developed by the Việt Nam National Satellite Center (VNSC), University of Tokyo and IHI aerospace. 437.250 MHz CW beacon and 437.365 MHz 1200 bps AFSK AX.25 telemetry.
ArduSat-1 developed by NanoSatisfi. 437.000 MHz 9k6 MSK CCSDS downlink.
ArduSat-X developed by NanoSatisfi. 437.345 MHz 9k6 MSK CCSDS downlink .
TechEdSat-3 developed by interns at the NASA Ames Research Center. 437.465 MHz 1200 bps packet radio beacon transmitting 1 watt to 1/4 wave monopole. It plans to test an Iridium Satphone modem and has a deployment mechanism to de-orbit in 10 days.

They are 1U in size (10*10*10 cm) except for TechEdSat-3 which is 3U (30*10*10 cm).

As well as the ISS deployment next week also sees two mass launches of satellites on Minotaur-1 and Dnepr rockets. In total 37 satellites carrying amateur radio payloads are expected to be deployed next week. The frequencies of these satellites can be seen at
