Hello All, The PSLV C-18 Mission is a Grand success. All the four satellites were successfully injected into their precise orbits. The Jugna was injected at 05:56 UT and the beacon will turn ON at 06:31 UT. It is expected that the Jugnu at that time should be somewhere over N.W of South Amer

Hi All, In response to Trevor's questions, the current board design is about 3.2 cm x 3.2 cm x 4 mm. At that size, we can fit about 200 in a 1U CubeSat (stacked 3x3x22). We're pretty sure we can thin that down a little more by using thinner PCBs. If we get way more than 200, we can always go to
