Integration and testing of a Radio Frequency bench

Missions A concept of space mission is under study which consists in dropping a nanosatellite near an asteroid to measure the gravitational influence of the asteroid. A "radio-science" signal is sent to the CubeSat which responds with a delay and a frequency offset. A series of measurements during the asteroid flyby allows to reconstruct the precise deviation of the CubeSat and to deduce the mass of the asteroid. Currently, a test bench on the ground aims at validating the concept. The supplies are made except for a transponder (S band) already identified. A part of the bench is already integrated. In addition, a data-processing chain must translate a flight scenario into equivalent tests on the ground test bench and analyze the measurements obtained. This mission concept is led by the IMCCE laboratory of Paris Observatory - PSL and has already received support from CNES, the ĂŽle-de-France region and the CENSUS space cluster of Paris Observatory - PSL. The engineer in charge of the test bench will have to continue the elementary tests of the components of the bench, namely: mobile vehicle equipped with a bluetooth antenna, a mini-camera, a Lidar, a transponder with an S-band antenna and an electric motorization-steering system, fixed transmitting station and reflector screens for the Lidar. Then he/she will have to define and conduct the functional integration tests including the purchase, preparation and reception of the transponder. He/she will coordinate the involvement of radio-frequency experts and scientists of the project to interface the control system of the bench with the computer processing chain.
Activités -Activités: -Finalization of the integration of the bench (in particular some electronic circuits) -Basic component test reports -Definition and results of integration tests -Detailed definition of the interfaces with the computer processing chain -Participation in project progress reviews -Monitoring and consulting on transponder technologies -Possible recourse to an expert consultancy in radio frequency
Compétences -Compétences: -Electronics (design and realization), Embedded electronics, C++ -Correct written English (all documentation in English), fluent spoken English -Experience in radio frequency testing will be an advantage -C++ programming in LINUX environment, git, occasionally MATLAB/OCTAVE, python -Demonstration and test culture (elementary and functional tests)
