A cluster of five cubesats,
known collectively as "BIRDS-1," was deployed from the International
Space Station in early July. The five tiny satellites each contain an amateur
radio transmitter (all using the same frequency) but no transponders for signal
relays. The mission's main project, according to the ARRL Letter, is to "use the constellation to carry out radio
communication experiments via a network of VHF/UHF amateur radio ground
stations around the world." You can listen for them on 437.375 MHz.  |
