According to the schedule, this master’s student will be in charge of the following tasks :
1) 1-14 Preliminary evaluation of SDR radios (ADS-B surveillance systems)
2) 1-22 Preliminary design and evaluation of the SDA architecture (ADS-B)
3) 1-34 Initial implementation of a software WBR-ADS-B module
4) 2-35 Design of a WBR SDA bench test setup configuration (ADS-B)
The general objective of this Master’s research project is to implement the functionalities of an Automatic Dependant Surveillance Broadcast (ADS-B) system : bi-lateral air to ground and air to air data transfer within a Software Defined Avionics (SDA) demonstrator. This student has the responsibility of conceptualization, design, integration and definition of the baseband aspects for the experimental transceiver. The primary objective is the integration of a real-time ADS-B application module within the principal SDA demonstrator, including the augmented functionality of interoperation permitting the use of other SDA applications such as DME, Transponder and Sat-Link. This experimental systems integration and research project will require static and flight test bench evaluations providing data for post-processing and performance assessment.
This will generate a better understanding of complementary sensing and processing capabilities including the analysis of various avionics data buses interconnections as well as operator interface for parameters settings. Where possible, real time data will be simulated and used as test signals for the transceiver’s automatic receive, broadcast and intersystem data communication functions. New algorithms to enable these various functionalities are required to achieve and demonstrate the defined performance. As part of the secondary objectives, an analysis of the various ADS-B protocols being studied worldwide will be necessary considering the risk and non-mature state of the operations specifications or protocols that majors Air Traffic Management (ATM) next generation consortiums like SESAR (Europe) or NextGen2020 (USA) are still defining. This research project will involve meticulous analysis of the existing stand-alone and sometimes non-mature systems, building on previously acquired knowledge, with a view towards simulation and tangible prototype performance. Bibliographical studies of the ADS-B and associated functions are required (part of the bibliography) but not limited to : FAA TSO C-129, C-145, C-146, RTCA DO-260, DO-260A, TC AC700-009, COCR V2, etc.
