ISS Amateur Radio CubeSats Deployed
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.
The Peruvian Chasqui 1 CubeSat was also onboard the ISS. At the time
of writing it is unclear if this has also deployed.

Successful launch of ham radio satellites
On Thursday, February 27 at 1837 UT a cluster of Japanese amateur
radio satellites were launched from the Yoshinobu Launch Complex at
the Tanegashima Space Center
At 1948 UT Francisco Jimenez-Martin Sanchez EA1JM received the
437.325 CW (A1A) beacon from the ARTSAT1:INVADER CubeSat
Also on the first pass at 1952 UT Jan van Gils PE0SAT received
OPUSat
STARS-II (comprises Mother and Daughter satellites)
TelkyoSat-3
ShindaiSat-1
ARTSat1:INVADER
The student team that developed the ITF-1 CubeSat would appreciate
any reports of their satellite on 437.525 MHz FM Morse code, see

LituanicaSAT-1 Lithuanian CubeSat
The amateur radio CubeSat LituanicaSAT-1, call sign LY5N, was
developed by Lithuanian university students and young engineers and
was deployed from the International Space Station (ISS) on
Friday, February 28.
The team ask radio amateurs and SWL’s to listen for the FM Morse
code beacon on 437.275 MHz after deployment and submit reports (see
Tracking below). They say there will be Mission emblem stickers with
signed QSL cards and for the first 10 registered reports,
LituanicaSAT-1 branded note books!
The tiny satellite is just 10x10x10 cm with a mass of 1.090 kg yet
it has a VGA camera and a 145/435 MHz FM voice transponder, designed
and built by Lithuanian radio amateurs.
The prototype of the FM repeater has been operating in the home of
its designer Žilvinas Batisa LY3H in Elektrenai, Lithuania. Further
information at http://ly3h.epalete.com/?p=303
The communications payload comprises:
• FM Morse Code Beacon 437.275 MHz LY5N
• FM Voice Repeater 145.950 MHz uplink (PL 67 Hz CTCSS) 435.180 MHz
downlink
• AX.25 Packet Radio 145.850 MHz uplink 437.550 MHz downlink 9600
baud FSK, FM
LituanicaSAT-1 uses passive magnetic attitude control system
consisting of permanent magnets that create a control torque and soft
magnets that provide dampening torque using hysteresis effect.
Following attitude sensors are implemented for attitude determination:
• PS-MPU-6000A MEMS motion sensor
• PS-MPU-9150A MEMS motion sensor
• L3GD20 MEMS three-axis digital output gyroscope
• HMC5883L three axes digital magnetometer
There are two computers in LituanicaSAT-1: the flight computer based
on ARM Cortex-M4F microcontroller and secondary (back-up) computer
based on Arduino ATMega 2560 microcontroller. These two computers and
their periphery are laid out on different sides of one shared PCB.
The flight computer is the central control unit of the satellite
responsible for maintaining the normal operating mode of the
satellite, monitoring and control of energy resources, control of
