M-SAT Missouri S&T Satellite Team SHOT II Pre-Launch Ryan Pahl Matt Campbell Stephanie Evans Austin Ferguson

2 Mission Overview The main purpose of this mission is to test the Bluetooth technology used to communicate data between MR and MRS SAT Compare the data sent and data received after recovery to determine success/failure rate

3 SHOT II / UN-6 Connection M-SAT consists of two separate satellites that will communicate using Bluetooth technology During the UNP-6 mission, MRS SAT’s GPS position data will be transmitted via Bluetooth to MR SAT where MR SAT will process the data for formation control purposes Verify Bluetooth operation over extended range

4 SHOT II Design and Test Details Each payload will contain a microcontroller and Bluetooth module –The microcontroller has an 8051 architecture –The Bluetooth module is a BlueGiga WT11-E Modules hidden to prevent interference During the testing, the prototype box proved that it was capable of surviving the extreme stress that may take place during the mission –~545 g per sat –Whip test –Drop test –Stair test

5 Expected Results The two payloads should be able to communicate throughout the mission –The transmitting box sat will send a string of characters in a repeating pattern to the receiving box sat –The transmitting box will record the number of characters sent and the receiving box will store the actual characters for later comparison A ground range test was performed and the boxes functioned to a distance of 155 m

6 Demonstration The two boxes will be separated to test the range of the Bluetooth A light has been placed on each box to display when the boxes are connected and transmitting
