Specifically designed to observe essential climate variables, UVSQ-Sat NG is a 6U nanosatellite, meaning that it has the dimensions of six stacked unit cubes, each cube having a standard size of 10 centimetres by. Weighing only 10 kg, UVSQ-Sat NG represents a true concentrate of technology. The satellite is equipped with a sophisticated attitude determination and control system designed to meet a variety of scientific requirements related to the observation of essential climate variables. This addition distinguishes it considerably from its two predecessors, UVSQ-Sat and INSPIRE-Sat 7. In a study published in the journal Remote Sensing Journal, a team of researchers from the Atmospheres Laboratory, Space Observations (LATMOS â CNRS/Sorbonne University / UVSQ), in partnership with industry, described this new space mission as well as its scientific aims. The satellite is scheduled to be launched in 2025. One of the objectives of UPSQ-Sat NG is to maintain the continuity of the EarthâÖs Radial Assessment studies initiated by the UVSQ-Sat and INSPIRE-Sat 7 satellites, launched in 2021 and 2023 respectively. The UVSQ-Sat NG mission also involves monitoring concentrations of greenhouse gases, such as carbon dioxide and methane, while analysing their links with infrared radiation emitted by the Earth. In addition to the methods used to determine the components of the EarthâÖs Radial Balance sheet from the instruments of the UVSQ-Sat NG satellite, researchers detail the technologies used to extract information on atmospheric gas columns (CO2, CH4, O2, H2O) from data from the miniaturised infrared spectrometer that will be on board UPSQ-Sat NG. Both scientific and innovative, this research project is primarily an educational tool, and is an exceptional educational platform for students who are actively involved in the design, implementation of the satellite structure, and the establishment of a satellite management and management centre. This programme aims to meet the requirements of enterprises and public bodies in terms of training, development of initial and continuous educational programmes, while at the same time increasing the attractiveness of these training courses. This is in order to ensure the acquisition of the key competences required for the emerging professions of France in 2030. UVSQ-Sat NG is equipped with several instruments, including radiative sensors (thermopiles with carbon nanotubes) for monitoring incoming solar radiation and outgoing terrestrial radiation. A near-infrared spectrometer is also on board to evaluate atmospheric concentrations of greenhouse gases by making observations in the wavelength range of 1200 to 2000 nm. In addition, UVSQ-Sat NG carries a high-definition camera designed to take images of the Earth in the visible spectrum. This NanoCam will facilitate the post-processing of spectrometer-based data by ensuring accurate geolocation of observed scenes. It will also offer the possibility of observing the EarthâÖs edge, thus giving an approximate estimation of the vertical temperature profile of the atmosphere. A scientific paper published in the journal, Remote Sensing states that, âThe Isispace VHF Receiver (RX) operates in the commercial frequency range of 148 to 150.5 MHz, and for amateur frequency coordination, it operates within the frequency range of 145.8 to 146.0 MHz. On the other hand, the Isispace VHF Transmitter (TX) covers the commercial frequency range of 400.15 to 402.0 MHz and, for amateur usage, it spans the range of 435.0 to 438.0 MHz. An audio transponder will also be used with the amateur radio community.â However, no amateur frequencies have been coordinated with the International Amateur Radio Union (IARU) and no amateur operation has been announced.
