アメリカ・コーネル大学の衛星 CUSat-1/2 が、2012年 秋に打ち上げられる予定
です。この衛星の目的・将来的な構想について、http://cusat.cornell.edu/ の
ホームページに詳しく解説されています。 9k6周波数、モードは次のとおりです。

Cornell University Space Systems Lab

CUSat-1/2 is a 45kg satellite that will split into two parts sometime
after separation from the launcher. Image and positioning data will be
downlinked using 9k6 AX25 packet on 70cm from a 2 watt transmitter.
Cross linking between the two parts will also take place on 70cm.

The coordinated frequencies are:
- CUSat-1    437.405 MHz
- CUSat-2    437.485 MHz
- Cross link 437.305 MHz

Using centimeter accuracy carrier-phase differential GPS, the two
satellites will perform autonomous relative navigation. One satellite
will capture imagery of the other satellite and send these images to
a ground station on Earth for the reconstruction of a 3-D model of
the partner satellite. The images will also act to verify the relative
GPS implementation. Doing so will demonstrate how one spacecraft can
diagnose the structural health and configuration of another.
