Presentation Transcript

  1. Violet: A High-Agility Nanosatellite for Demonstrating Small Control-Moment Gyroscope Prototypes and Steering Laws • Slides and presentations by: • David Bjanes • Rajesh Atluri • SHOT II Pre-Launch Presentation • June 10-13th, 2010 • Boulder, Colorado

  2. SHOT II: Mission Overview Payload GPS Receiver Board GPS Interface Board ATmega32 Microcontroller Board with sensors to measure temperature, acceleration Goals Collect telemetry during flight Log GPS data on to flash memory on the ATmega32 microcontroller board Download data stored post-flight from flash memory

  3. SHOT II: UN-6Mission Relevance: The GPS system is a critical part of the Violet mission SHOT II payload includes components from Violet design: • Active Antenna • GPS Receiver Board • GPS Interface Board We intend to demonstrate the ability to gather and store GPS data during flight Violet GPS System

  4. SHOT II: Design Details Foundation SHOT I payload with ATmega32 microcontroller Modifications GPS Orion Receiver Board - L1 Band frequency: 1575.42 MHz - 12 Parallel Tracking Channels - Active Patch Antenna GPS Interface board - Serial Interface (RS232)

  5. SHOT II: Compliance & Test User Guide Compliance Mass: 700 grams Payload attaches to flight string through a pair of holes on the top and bottom Test Program The satellite box was tested for structural integrity using the whip, drop, and stairs test. The flight payload was tested on the lab bench by running flight code for the expected duration of the launch. 5

  6. GPS Orion Memory Data for analysis RS232 Parser SHOT II: Expected Results • We expect to store the following data on to the flash memory on the Microcontroller board: • Telemetry from sensors • GPS data output by the GPS Interface Board • We expect to read this data on the flash memory using a data parser application. • Example data will be shown as part of our demo.

  7. SHOT II: Demo GPS data retrieval Previously ran flight code Download data stored in flash memory onto PC
