If you have a question about this talk, please contact Silvia Toonen. The space based GW detector `Laser Interferometer Space Antenna’ (LISA) will probe the low-frequency GW sources such as mergers between massive Black holes and compact binaries amongst others. LISA is an ESA mission with NASA partnership and a planned launch date in 2034. To achieve the science goals, the interferometry that will measure the distance variations between freely falling test-masses is required to achieve picometer sensitivity in the LISA observational frequency band. A number of instrumental noises will be suppressed in a post-processing pipeline on ground. The LISA data processing involves several successive processing steps of the telemetry of the data onboard the 3 spacecrafts (SC) and other auxilliary ground data leading to the main scientific products. This presentation will give an overview of the first leg of the LISA data processing step defined as level 0 (L0) to level 1 (L1) pipeline. The simulation of L0 data which are mainly the interferometric signals, psuedorandom noise ranges and their processing which includes steps such as the synchronization of the digitised time-series, extraction of accurate time delays between SC and the usage these outputs to carry out the time delay interferometry will be explained in producing the L1 data. The major sources of noises in these processing steps with (ongoing) studies of their mitigation will be highlighted in the L0-L1 processing pipeline: Initial Noise REduction Pipeline (INREP).
