According to NanoRacks the deployment of the second batch of CubeSats from the International Space Station (ISS) will commence at 1700 UT on Tuesday, February 25, 2014. The CubeSats deployments were streamed live at http://m.ustream.tv/channel/live-iss-stream
Earlier this month astronaut Koichi Wakata KC5ZTA successfully deployed the first part of the Flock-1 constellation comprising 16 Dove 3U CubeSats developed by Planet Labs. The remaining 12 Dove CubeSats along with the amateur radio CubeSats LituanicaSat-1, LitSat-1, ArduSat-2, UAPSat-1 and the 915 MHz SkyCube should be deployed in the second batch.
The amateur radio CubeSats may be deployed on Friday, February 28 at 0730 UT. Another amateur radio CubeSat the Peruvian Chasqui 1 was sent to the ISS on February 5, 2014. It is not yet clear if this will also be deployed on Feb. 28.
Eight NanoRacks deployers are installed on the Multi-Purpose Experiment Platform (MPEP). Each deployer has a capacity of 6U and so can hold up to six 1U CubeSats or two 3U CubeSats. They are carried by Japanese Experiment Module-Remote Manipulator System (JEM-RMS).
Two 3U CubeSats (6U total) can be deployed every one to two orbits to prevent collisions. For the first batch of Flock-1 CubeSats about two deployments took place each day.
LituanicaSat-1 carries a 145/435 MHz FM transponder while LitSat-1 has a 435/145 MHz linear transponder for SSB/CW communications.
The IARU coordinated frequencies are listed as:
• 9k6 MSK CCSDS data format downlink 437.? MHz
Chasqui-1 (Peru) was launched to the space station on February 5, 2014. It is understood that it is scheduled to be hand-deployed during a future Russian Extravehicular Activity (EVA).
• AX.25 Packet Radio downlink on 437.250 MHz http://www.chasqui.uni.edu.pe/eng.html
