ELaNa-5 cubesats

Twelve CubeSats are set to launch aboard an Atlas V rocket with the NROL-39 primary payload from Vandenberg AFB in California on December 5, 2013. The CubeSat payloads have been provided through NASA's Educational Launch of Nanosatellites (ELaNa) program and the NRO's Mission Integration Directorate (MID). Atlas V GEMSat Launch 2013

IPEX (Intelligent Payload Experiment)
Cal Poly
Mission  to demonstrate operation of autonomous instrument processing, downlink operations, and ground station operations, utilizing the SpaceCube Mini payload processing unit to validate a reduction in data product downlink.




Call sign: KJ6KSL
Frequency: 437.270 MHz
Modulation: AX.25 FSK (NRZI with G3RUH scrambling)
Data Rate: 9600 Buad
Beacon Info:
IPEX transmits three types of beacons:
-Health Beacon: Contains the latest snapshot of IPEX telemetry
-File Beacon: A portion of a much larger telemetry file, need to collect several file beacons
  to reconstruct the file (HEX data)
-Morse Code: 15 wpm, should spell “IPEX,” will be disabled after initial tracking to conserve power

CAPE-2 received

CAPE-2 received   CW --- Voice --- Packet


$50SAT Received

I copied a wonderful signal from Eagle-2 – very clear and very strong .
The primary purpose of $50SAT (Eagle2) was to create a cost effective platform for
engineering and science students to use for developing real world skills

Real Time Data Providers

It is  fun to monitoring the warehouse.funcube webpage and see the data provider  in and out  - I've selected a random 3 stations, when the Funcube was over west Europe and one station from Australia , here some of their setup photos de QRZ.COM

GomX-1 Modulation !!!

GomX-1 transmitting a strong signal every 10s









GomX-1 does not use the standard AX.25 or AFSK format used for packet communication
GomX-1 uses 4800 baud MSK modulation at the two tones 2400 and 4800. This mode is not supported by most major TNC providers. So the recommended receiving option is to record the audio from the entire pass, using the line-in port on a PC with correctly adjusted amplitude. These recordings can then be software demodulated by gomspace.

A softare modem, based on GNURadio will be released soon. If you are interested in helping developing and testing a software modem for MSK, please say so.

MOVE Telemetry Receiver !!

MOVE Telemetry Receiver , simple nice program ,works as it is!!
Works ok with analog rig ,but with some difficulty due to new keps and for the long time between telemetry packet.!!
With IQ audio works very easy - audio rooted via XP Window Mixer to the selected audio input devise -
Replay via HDSDR ,Keep audio level low  about 20% for easy decoding  .....















First Move-1 Cubesat HP

Warbler – 1200 Bit/s BPSK AX.25 soundcard demodulator.

My friend San  Satou Tetsurou decoded Move cubesat by  Warbler !
Warbler is a piece of software which can be used to demodulate a 1200Bit/s AX.25 BPSK signal (e.g. from AMSAT-OSCAR 16/PACSAT or ITAMSAT-OSCAR 26), using the PC’s soundcard.

I've re tested with move IQ audio file .
Here is San  Satou Tetsurou screen shot followed by mine
