Data Exfiltration of Unattended Ground Sensor Data Using a 3U CubeSat

The technical objective for the Phase II effort is the mitigation of key technical and implementation risks of the program, as well as the development, test, and verification of an end-to-end Data Exfiltration system using a 3U CubeSat. The end-to-end demonstration will take the form of a system testbed, which will include CubeSat avionics, CubeSat Payload elements (e.g., deployable high gain dish, transceiver with low power mode), and UGS (i.e., UGS controller, Satellite Gateway transceiver/antenna). The end-to-end testbed will be used to demonstrate the critical need-lines described in the Phase I architecture description and key transitions between low power receive and burst data modes. Some of the key space vehicle elements will go through environmental qualification testing to mature components to TRL 5-6. Since most of the 3U CubeSat bus has heritage to Tyvaks current development and product lines (components currently TRL 5 or 6), the focus of development will primarily be on the Payload elements and new Bus development (e.g., tracking solar array)
