Time-oriented management of telemetry data

Reliable tracking system is crucial for the development of long range ground-to-ground rocket. Commercial-off-the-shelf systems can be too expensive to implement during research and development phase. With a simple framework, we develop an in-house prototype of data collecting unit (DCU) and a base unit to manage transmitted rocket data. The DCU acts both as a wireless receiver and data storage. It can also transmit data upon request. A base unit sends a command to control DCUs during data retrieval process. Putting DCUs at an appropriate distance, we can effectively receive all transmitted data. It is evident that DCUs located at 2.5 km apart along the flight path have a combined high percentage of reception performance.
