CubeSat Storage and Communications Card (C-SaCC)

Active Technology Project

Project Introduction

Science and housekeeping data generated on a CubeSat can be collected for hours or days between opportunities to downlink, but each downlink window provides only a few minutes of time to transfer this data to the ground.  Most transceivers which handle this task provide little buffering of this data, and when the C&DH processor has a slower serial link it limits the effective downlink rate of the transceiver.  An integrated onboard mass storage and transceiver interface card would mitigate this limitation and allow downlink rates at the maximum rate of the transceiver while allowing the C&DH to forward downlink data over a slower serial interface.
