AbstractOne of the major advantage of integrated Network Enhanced Telemetry (iNET) system is data backfill. In the iNET, network data server requests signal retransmission from the on-board recorder when the signal dropout is detected, and data is retransmitted which leads successful reception. If there are numerous test articles (TA), however, multiple backfill process for signal request and data retransmission can cause undesirable capacity waste. This paper describes the improved backfill process in iNET with multiple TAs. This process includes grouping and scheduling algorithm within TAs, and the orthogonal and non-orthogonal transmission. The system model and results are analyzed by simulation.
