A Frame-Based Combining Method for Telemetry Data

摘要

Ground stations in multiple receiver telemetry systems receive flight data independently in different locations. In these systems, flight data from different sources should be selected in the most accurate combination. There has been word-based telemetry data combining methods in the literature. These methods select each word in telemetry frame independently. In this paper we introduce a frame-based selection method, considering that errors in telemetry systems affect many words in a frame at once. The method we introduce selects all the words in a frame from one source. We compare the effectiveness of the two combining methods using real flight data and demonstrate the superiority of our method.
