2. Mission Overview: The mission is to test our COM board, which is based on the MHX-2420 transceiver. We plan to establish a real time link between the ballonsat and mobile ground station with which we will be monitoring satellite health conditions.

3. SHOT II / UN-6 Connection: -UN-6 mission is to provide orbital radar calibration support to the Air Force by collecting and disseminating ephemeris data in response to radar interrogation -UN-6 payload hardware is undergoing space environment testing provide by our customer -COM subsystem supports interrogation schedule uplinks and ephemeris data downlinks -SHOT II provides the COM subsystem with communication and operational testing in a near space environment
