The Integration of Ground-based Real-time Telemetry Processing, On-board Chapter 10 Aircraft Data Recorders, and 802.11G Links

摘要

As part of the iNET Team's plan to demonstrate to the validity and benefits of adding a network connection to a test vehicle, Wyle Laboratories Telemetry and Data Systems is developing a network-based command structure that allows ground-based users to request data previously archived on-board a test article in response to real-time data monitoring. This synthesis of real-time telemetry monitoring with traditional ground-based post-test data analysis provides flight test engineers with near real-time, error free data while the aircraft is on station. Additionally, this approach maximizes the use of available telemetry bandwidth by allowing users to dynamically request different data sets for downloading. This paper addresses the command structure of the interface; the utilization of IRIG 106 Chapter 10 data structures in a network environment, and provides performance metrics of the test case.
