Telemetry and Data Systems' Best Data Engine (BDE) provides an innovative and revolutionary method to dynamically blend all incoming data streams into one composite data stream for output or internal data processing. Typical Best Source Selectors apply metrics to each incoming source of the same data stream coming from different locations on at test range and dynamically switches to the source with the strongest signal characteristics. While this improves the quality of the source being used for data processing and real time display, there are still some errors in this stream and some data is lost during the switching process due to the different transport delays from data coming in from different distances from the main mission control center. Smartronix-TDS has found a way to provide much higher fidelity data by dynamically buffering all the sources arriving in the main mission control location and looking at each stream on a bit by bit basis. Our Best Data Engine than uses a bit voting algorithm to build a composite data stream from all the data streams during the entire mission. This effectively eliminates the errors from any one stream and also eliminates any data loss from switching from one stream to another. This revolutionary breakthrough allows Smartronix-TDS to provide the highest quality data output possible based on multiple data stream inputs.
