Raspberry Pis have certainly been designed into cubesats but have not tracked down any overall listing of number actually launched, how well they operated or any lessons learned. Related questions include this one on Pi's and this on code design. The three questions overlap, and tie back to hardware design. Hardware side the first task is to ensure the the ...

I was looking for a constellations of smallsats (they are not cubesats) that were able to space themselves out using only drag. I hypothesized it was TROPICS but that hasn't been launched yet. But I finally found it, and it turns out to be CYGNSS and is discussed in How can the CYGNSS spacecrafts (actually) measure ocean roughness?. The technique is called ...

There’s a 2017 federal “Sources Sought” for launch services for TROPICS. The relevant part is: Therefore, 6 to 8 TROPICS CubeSats will be placed in a constellation formation as described in the three scenarios included in the attached document. All of the CubeSats are identical and must be placed into their operational orbit within 60-days (first ...

@Uwe made a clear case why this may not be feasible using the DSN as an example. I'd like to add that some of the assumptions you list in the comments are not correct. I'm not sure how you come up with 470W generation from the solar panels you linked (cubesatshop.com/product/solar-panels), but the numbers listed on their site are most certainly rated for LEO ...

You want to use a X-band communication link from a cubesat in Earth orbit to another cubesat in orbit around Titan? I don't think it is possible, at least at an acceptable data rate. Lets compare this link to a deep space probe down to the DSN antennas in Goldstone, near Madrid and Canberra. Deep space probes use a transmitter with about 10 to 20 W power, ...

There are too many general questions here that require book-chapter-length-like answers. I would like to specify first: Do you want to calculate antenna performance, antenna pattern, or what exactly? Additionally, which antenna do you have in mind: ground station antenna for an uplink scenario, antenna on-board of the CubeSat for a downlink? In terms of ...

You'll be definitely better off with thrusters on individual cubesats, when taking the total mass: last stage + payload, into consideration. To create the distance needed, with a single launch, you'll need to put the satellites into an elliptical orbit tangent to the target one, but of period longer or shorter by 1/8 or an integer fraction multiple of 1/8. ...
