On Friday, February 28, 2014 at 0730 UT astronaut Koichi Wakata KC5ZTA deployed a batch of amateur radio CubeSats from the International Space Station (ISS).

LituanicaSAT-1, LitSat-1, ArduSat-2 (2U), UAPSAT and the 915 MHz SkyCube were successfully ejected from a NanoRacks deployment pod.

At 0855 UT Dmitry Pashkov UB4UAD received the LituanicaSAT-1 beacon. and received LitSat-1 at 1030 UT.

At 1022 UT Mike Rupprecht DK3WN received LitSat-1. Mike had heard UAPSAT at 0845 UT.

There is another amateur radio Cubesat still on the ISS, the Peruvian Chasqui-1 which was launched to the space station on February 5, 2014. It is understood that Chasqui 1 is scheduled to be hand-deployed during a future Russian Extravehicular Activity (EVA).

The first of the Planet Lab Dove CubeSats were deployed from the ISS on February 11, 2014 about 0831 UT

On Tuesday, February 11, 2014 astronaut Koichi Wakata KC5ZTA successfully deployed the first of the 33 CubeSats that were launched from the Wallops Flight Facility, VA to the International Space Station (ISS) in the Cygnus freighter on January 9.

The first two of the Flock-1 constellation of 28 Dove 3U CubeSats developed by Planet Labs were deployed at about 0831 UT Feb 11 into a 409 x 418 km orbit with another two Dove CubeSats deployed at 1241 UT.

ISS Kibo Japanese Experiment Module (JEM)

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 can be deployed every one to two orbits to prevent collisions. For Flock-1 two deployments took place each day.

1055 Feb 15 – Flock-1-15, Flock-1-16 (39531, 39532)

The deployment pods were then returned to the airlock to be loaded with the final batch of CubeSats.

Planet Labs CubeSat Constellation

In addition to the 28 Planet Labs CubeSats there are four amateur radio CubeSats – LituanicaSat-1, LitSat-1, ArduSat-2, UAPSat-1 – and the 915 MHz SkyCube.

LituanicaSat-1 carries a 145/435 MHz FM transponder while LitSat-1 is thought to carry a 435/145  MHz linear transponder for SSB/CW communications.

The IARU coordinated frequencies are listed as:

LituanicaSAT-1
• FM Transponder Uplink 145.950 MHz Downlink 435.180 MHz
• AX25 Uplink 145.850 MHz AX25 Downlink 437.550 MHz
• CW Beacon 437.275 MHz
