INS Data Collection System Presenter: Curtis Cutright Advisor: Dr. Michael Braasch

2 Purpose: This project will develop a method of using INS data to update position and velocity data during loss of GPS lock Software development and modification are the primary focus at this time Hardware installation and system configuration are also being evaluated Future testing may include the collection of control system data

6 Data Collection INS data will be collected on the PC-104 computer through the ARINC card Time tagging will be accomplished using the CPU clock GPS data collection software will be added later

7 Software Development Considerations ARINC card is configured for high speed receive and low speed transmit Initialization data is transmitted in 2 to 4 bursts on the low speed bus INS data is received on the high speed bus Labels can be used to mask unwanted outputs

8 Hardware Configuration Considerations Encoding altimeter will be replaced with a variable potentiometer Control Display Unit (CDU) could be replaced with a 4 position switch or 2 single throw switches

9 Conclusions Data collection system is still in development As the development continues changes will be made to the early versions of the software Other types of hardware that will be integrated into the system will drive these changes
