Golf-Tee does not power down the standby processor. It is still handling its own telemetry and also keeping its on MRAM up to date with whole orbit data, not to mention running the command receiver. But remember Golt-TEE is a 3U with fold-out panels.

Power requirments is something we need to be looking at carefully.
I found this on the web:
https://pressbooks-dev.oer.hawaii.edu/epet302/chapter/5-5-power-generation/
We can look at some data from other cubsats for power generation. Reviewing Falconsat-3 telemetry would be a good idea.
Power and thermal design will play off each other.
With a 2.5 W power budget for a cubsat the pacsat payload could be a large power consumer. May effect ability to get onboard.
If Golf T had two of the TMS520 one must have been powered down until needed?
Designing for minimum power will yield more operating time and a longer mission life. Falconsat-3 is demonstrating this point now.
