OPTIMIZING FLIGHT SHOCK AND VIBRATION MEASUREMENT BY RF LINKSWalter, Patrick L. 10 1900 (has links)
International Telemetering Conference Proceedings / October 26-29, 1998 / Town & Country Resort Hotel and Convention Center, San Diego, California / Acquiring shock and vibration data from flight vehicles through rf telemetry links has numerous associated challenges. Yet, these measurements are important to establish environmental specifications to provide a basis for system or component design and testing. The principal limitation in acquiring these measurements is the frequency bandwidth available for data transmission. This limited bandwidth is often responsible for invalid data being accepted as valid. This work provides a brief review of time and frequency division multiplexing to identify the potential error contributors to shock and vibration measurements. Its focus is on the design of acceleration measurement systems to eliminate these errors and optimize individual measurement channel performance.

NETWORKING SATELLITE GROUND STATIONS USING LABVIEWMauldin, Kendall 10 1900 (has links)
International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / A multi-platform network design that is automated, bi-directional, capable of store and forward operations, and low-bandwidth has been developed to connect multiple satellite ground stations together in real-time. The LabVIEW programming language has been used to develop both the server and client aspects of this network. Future plans for this project include implementing a fully operational ground network using the described concepts, and using this network for real-time satellite operations. This paper describes the design requirements, RF and ground-based network configuration, software implementation, and operational testing of the ground network.

SATELLITE GROUND STATION SECURITY USING SSH TUNNELINGMauldin, Kendall 10 1900 (has links)
International Telemetering Conference Proceedings / October 20-23, 2003 / Riviera Hotel and Convention Center, Las Vegas, Nevada / As more satellite ground station systems use the Internet as a means of connectivity, the security of
the ground stations and data transferred between stations becomes a growing concern. Possible
solutions include software-level password authentication, link encryption, IP filtering, and several
others. Many of these methods are being implemented in many different applications. SSH (Secure
Shell) tunneling is one specific method that ensures a highly encrypted data link between computers
on the Internet. It is used every day by individuals and organizations that want to ensure the security
of the data they are transferring over the Internet. This paper describes the security requirements of a
specific example of a ground station network, how SSH can be implemented into the existing
system, software configuration, and operational testing of the revised ground network.
