The Uvsq-Sat NG communication subsystem is tasked with establishing and maintaining
communication links between the satellite and ground stations. Its primary goal is to
enable the smooth transmission of data, commands, and telemetry information to and from
the satellite. The key components of this subsystem include the TRXVU communication
device (UHF/VHF band), the UHF/VHF antennas, the TXS high-data-rate S-band transmitter,
and the S-band patch antenna. The S-band downlink, with the platform oriented towards
Nadir, falls within the frequency allocation of 2200 to 2290 MHz.
The 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. https://www.mdpi.com/2072-4292/15/19/4876

Also among the satellites on the manifest for the SpaceX Rideshare 13 launch is the
third of a series of French cubesats, named UVSQ-Sat NG - or "Next Generation". The
previous satellites in this series carried amateur radio FM transponders. 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 – 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 Earth's 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 Earth's 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 Earth's 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, "The 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."
However, no amateur frequencies have been coordinated with the International Amateur
Radio Union (IARU) and no amateur operation has been announced.
