Mackie Control, HUI and Baby HUI MIDI Controllers Supportįluctus includes Real-Time built-in processing and metering solutions, that take advantage of the cDSP Engine. Waveform and Spectrogram Export as PNG and SVG To make it right for everyone, Fluctus ships in two versions, Fluctus and Fluctus Expert. Individual Mute, Phase Reverse, Panning and Gain Controls Individual Fade-in & out (4 optional shapes) Regions represent Audio Files imported or recorded and you can have as many audio regions as you need in a single Fluctus Project.įully Editable (including Lock, Split, Resize, Reverse and much more)ĭrawable Waveform (sample by sample editing) The proposed approach will allow for a physical retrieval of the three above properties, including a-posteriori retrieval uncertainties for all parameters.All Editing and Recording are done via rearrangeable rectangular blocks called Regions. The objective is to implement and validate a 1D-Var retrieval of TCWV, WTC and LWP for Sentinel-3 MWR. In this context, Informus and Fluctus SAS provide scientific development, prototyping, validation and quality definition for Copernicus Sentinel-3 Microwave Radiometer (MWR) Total Column Water Vapour (TCWV), Wet Tropospheric Correction (WTC) and Liquid Water Path (LWP) products. In this context, requirements on accuracy, sensitivity, and long term stability of the atmospheric water vapour observations are particularly strong since altimetry missions require a precision better than 1.4 cm in WTC (RMS) and a temporal stability better than 0.3 mm/year. To provide the observations required for the WTC is the primary role of the nadir looking Microwave Radiometer (MWR) embedded into the altimetry missions on board Sentinel-3. The spatial and temporal variability of water vapour is such that an instantaneous estimation of its impact is needed. Accurate: it benefits from a 15 years experience on every aspects of the end-to-end simulation, including the atmospheric physic, the instrumental measurements principles and the ground processingĬollaboration with Informus for Eumetsat on the definition of a wet tropospheric correction for Sentinel-3.Ī major source of uncertainty for Sea Surface Height estimates from radar altimetry is the wet tropospheric correction (WTC).Realistic: the high-resolution (~ 1 km) geophysical scenes on any surfaces are computed from the combination up-to-date NWP analysis and Radiative Transfert Model.Flexible: adaptable to any instrumental concept (CubeSat, Nadir, Imager, Sounder).The comparison between the known reference and the output from a ground prototype processing allows to quantify the expected performances of a given design and to verify if the mission requirements are satistified (Performance Analysis). For a microwave radiometer, the two critical parts are the antenna reflector and the radiometric line.īoth are tested in the frame of a realistic environment provided by accurate generation of the geophysical situation (scene generator) and detailed simulations of the measurement process (Antenna Processing and Instrument Module). Fluctus SAS is currently developping a generic solution for Microwave Radiometer End-to-end simulators.Īn end-to-end simulator is a key element in the design of a new instrumental concept.
