The knowledge of the inner structure of Jupiter, in particular the central region, would bring unique constraints on the Solar system formation scenario. Nowadays, the inner structure of Jupiter is poorly constrained and seismology, which consists in identifying planetary acoustic eigen modes, is the only way to investigate the core region. Seismology of Jupiter has been considered since the very beginning of seismology of the Sun, because of their common fluid nature, leading to similar oscillations and same techniques to search them for. From 1980 and 1990's experiments, emerged the need for a specific instrumentation, able to combine high spectral resolution and spatial resolution. The SYMPA instrument is a Fourier tachometer developed at Observatoire de la Côte d'Azur (Schmider et al. 2007, A&A 474, 1073 and Gaulme et al. 2008, A&A 490, 859). Two instruments were built and simultaneously used during 2 observation runs in 2004 and 2005 at San Pedro Martir and Teide observatories. In this presentation, we show a new analysis of the 2005 data set, where we detect several oscillation modes of Jupiter. In particular, we measure an excess power in the frequency range [800, 2000] µHz and a mean frequency spacing between the modes of about 155+/-1 µHz, which corresponds with the theoretical expectations from Gudkova et al. 1999 (PSS 47, 1211).
