CubeSats are very small satellites shaped as 10cm (~4-inch) cubes with mass
less than 1kg (~2.2-pounds). The CubeSat Project is a collaborative
effort between California Polytechnic State University - San Luis Obispo and
Stanford University’s Space Systems Development Laboratory. Much more
information can be found in official CubeSat web pages starting at http://cubesat.atl.calpoly.edu/ and
in numerous CubeSat project web pages given in tables below.
Also
see information about all OSCAR (Orbiting Satellite Carrying Amateur Radio)
spacecraft including CubeSats maintained
by Mike Rupprecht, DK3WN, via http://www.dk3wn.info/calendar/satellit.php?language=german.
The very small ~$75,000US project budget for each CubeSat (including launch fees) has made the program very popular with educational institutions. See SPACE.COM article, Cubesats: Tiny Spacecraft, Huge Payoffs, for more information via http://www.space.com/businesstechnology/cube_sats_040908.html. Also see SCIENCE NEWS For Kids article, A Satellite of Your Own, http://www.sciencenewsforkids.org/articles/20060315/Feature1.asp
The majority of CubeSat projects are using Amateur Radio licensing, frequencies, techniques and equipment for telemetry downlinks and command uplinks. Many projects have extensive up-to-date web pages where information covering Amateur Radio call signs, frequencies, transmission modes, telemetry decoding and/or telemetry reception software is (or will be) available.
Given this information, Amateur Radio operators and others worldwide will know when each individual CubeSat will be above their horizon and how to receive, capture and decode telemetry. Recovered telemetry data can then be forwarded to CubeSat project teams as a valuable resource to spacecraft operations. CubeSat information required for this support is collected below.
In addition to CubeSats in orbit or in final preparations for launch there are numerous CubeSat projects in progressive stages of design and fabrication. See the Developer List available via http://cubesat.atl.calpoly.edu/pages/satellite-developers.php for links to further information.
The Mk III. P-POD Interface Control Document (ICD)
and the CubeSat Design Specification (CDS) have been updated and are now on the
CubeSat website. The Mk III. P-POD has incorporated changes based on
both experience with launch providers and feedback from the CubeSat community.
The major change for developers to note are the larger ports, now on two sides
of the P-POD instead of only one. There is also more detail regarding the
P-PODs history and testing procedures. The CubeSat Spec updates the
areas available to access once inside the P-POD, and adds detail to the
existing requirements. The new documents are now the ones which
should be followed. CubeSats designed to the old specification should
still be compatible with the new one.

Based on our initial orbit analysis, first signals of the Delfi-C3 satellite are likely to be heard while the spacecraft is still in the first orbit, after it comes out of the first eclipse over the Northwestern USA and on towards Alaska.
