OSSI-1
  Open Source Satellite Initiative
  Nation: South Korea
  Type / Application: Technology
  Operator: OSSI
  Equipment: Transceiver, LED-array
  Configuration: CubeSat (1U)
  Power: Solar cells, batteries
  Mass: 1 kg
  Orbit: 290 km × 575 km, 64.9 deg
  Frequency: 145.980 MHz CW, 437.525 MHz 1k2

  The 950 g satellite has a beacon in the 145 MHz band and a data
  communications transceiver in the 435 MHz band. This innovative
  satellite carries a 44 watt LED array to flash Morse Code messages
  to observers on Earth. Radio hams can reserve messages by sending
  signals to the satellite then observers can see the messages at
  the scheduled time in a flashing Morse Code LED pattern.

  OSSI-1, the Open Source Satellite Initiative satellite, developed by
  Hojun Song DS1SBO, is planned to launch in the 2nd quarter of 2013 
  into a 575 km 63° inclination orbit on a Soyuz-2-1b rocket from the
  Baikonur launch facility in Kazakhstan. The 1U cubesat is 100% based
  on COTS components. The main payload, the Bion-M1 satellite, antici-
  pates a planned launch in April, 2013.

  Reports say OSSI-1 will have a beacon in the 145 MHz band, a data
  communications transceiver in the 435 MHz band although actual ope-
  rating frequencies have yet to be published. The data communications
  transceiver is reported to be using an open protocol, details have
  not been released yet. 

  OSSI-1 also carries a 44 watt LED optical beacon to flash Morse Code
  messages to observers on Earth.

  The development of the satellite has been documented on the Open
  Source Satellite Initiative Blog http://opensat.cc/blog/ and the
  Wiki http://opensat.cc/wiki/, Telemetry format

SOMP
  Student's Oxygen Measurement Project
  Nation: Germany
  Type / Application: Technology
  Operator: DresdenTechnische University
  Configuration: CubeSat (1U)
  Power: Solar cells, batteries
  Mass: 1 kg
  Frequency: 437.485 MHz (Actually 437.503 MHz)
  1k2 and 9k6 BPSK

  SOMP is from Dresden University of Technology and has sensors to measure
  atomic and molecular oxygen in the upper atmosphere. It will also be used
  to measure performance and degradation of thin film solar cells in space.

  [Report by VK5HI, 23Apr2013]
     SOMP = 39135U 13015F
     SOMP noted on 437.504 MHz, not 437.485 as published.
     Signals 25dB above ambient noise.
     CW beacon at 2 minute 30 second intervals,
     as is high speed CW (1 minute prior to CW)

BEESAT-2/3
  Berlin Experimental Educational Satellite
  Nation: Germany
  Type / Application: Technology
  Operator: Technische Universitat Berlin
  Configuration: CubeSat (1U)
  Power: Solar cells, batteries
  Mass: 1 kg
  Frequency: 435.950 MHz, 4k8 GMSK

  BEESAT-2 is a cubesat-sized vehicle carries a technology experiment
  using gyros and sensors for precise orientation.
  BEESat-3 is another cubesat-sized vehicle that will test high-speed
  data links (up to 1MB/s). Telemetry format

Bion-M1 (non-amateur)
  Nation: Russia
  Type / Application: Life Science
  Configuration: Yantar Bus
  Power: 2 deployable solar arrays, batteries

  Research satellite collaboration between NASA and the Russian Institute
  of Biomedical Problems. The mission will launch an unmanned automated
  spacecraft carrying a biological payload into Low Earth Orbit (LEO).
  The rodents on the Bion-M1 spacecraft will be exposed to spaceflight
  conditions for approximately one month.

  Bion-M is the next generation of russian biological research satellites.
  While retaining the Vostok/Zenit-derived reentry module of the earlier
  Bion, the propulsion module has been replace by a Yantar type module,
  which provides maneuvering capabilities and longer mission support.
  The mission duration has been increased to up to 6 months by using solar
  cells for energy generation. The weight of scientific equipment has been
  increased by 100 kilograms.

AIST-2
  Nation: Russia
  Type / Application: Technology
  Contractors: Samara Aerospace University, TsSKB Progress
  Power: Solar cells, batteries

  AIST is a small satellite designed by students of the Samara State
  Aerospace University and built by TsSKB Progress, also at Samara.
  It will measure the Earth's geomagnetic field and test out a new
  satellite design. It will be attached to Bion-M at launch and will
  be released from the main spacecraft at some point in the mission.

Dove-1/2
  Nation: USA
  Type / Application: Technology
  Operator: Cosmogia Inc.
  Configuration: CubeSat (3U)
  Power: Solar cells, batteries
  Lifetime: ~14 days (#1); ~180 days (#2)
  Mass: 5.5 kg
  Orbit: 280 km x 270 km, 51.6 deg (#1); 290 km x 575 km, 64.9 deg (#2)

  The Dove-1 mission is a technology demonstration nanosatellite based
  on the triple CubeSat form factor:
  The goal of the mission is:

  * build a low-cost imaging satellite with non-space, COTS components;
  * to show that a bus constrained to the 3U cubesat form factor can
    viably host a small camera payload; and
  * demonstrate the ability to design, produce and operate satellites
    on short schedules and low cost.

  Dove-1 will do this by transmitting health and image data to the ground.
  The satellite will be launchd as a secondary payload on the maiden
  flight of the Antares-110 launch vehicle in 2013.

  The Dove-2 mission is also an internal company technology demonstration
  experiment to test the capabilities of a low-cost spacecraft constrained
  to the 3U cubesat form factor to host a small payload. It will be
  launched in 2013 as a piggyback payload on a Soyuz-2-1b launch.
