| Over the past 10 years, advances in electronics have enabled the development of more complex unmanned vehicles and probes, manufactured using publicly available off-the-shelf components (COTS), whether for industry or science purposes. In terms of aerospace exploration, the CubeSat is the best example of a complex device designed partially or fully using commercial COTS. However, the financial cost is still a concern, but not entirely an issue that stops the project entirely, since some inexpensive components can be tuned to meet the desired requirements and improve reliability. In the case of stratospheric probes and nanosatellites, the Telemetry, Tracking and Command (TT&C) subsystem responsible for data uplink/downlink can be enhanced by inserting error correcting code (ECC), allowing the use of commercial transceivers of low cost. This ECC can be included in the Command and Data-Handling (C& DH) as well, more specifically in the data storage, so the data collected inside the memory cards/hard drives can be less susceptible to corruption. To develop a data format that concatenates the information of several inertial and environment sensors with the information of a JPEG image that includes our implementation of the error correcting codes based on a correction method called Reed- Solomon (RS). We called to our version shortened interleaved Reed Solomon or siRS. The data format is going to be tested by passing it through a burst-bit-error channel (BBEC), where a regular file is expected to be corrupt, and measuring the Bit-Error-Rate (BER) and the Signal to noise ratio before and after the respective siRS coding/decoding. Also, we are going to perform a data downlink using commercial low-cost transceivers and a test probe that includes inertial sensors, environment sensors, a camera and an ARM-based mini-PC as on-board computer(OBC). The flight software, as well as the receiver ground station software has the algorithm to perform the siRS and generate the data packages. | |
