Abstract
High energy stereoscopic system (HESS) is a recent operational detector dedicated to the observation of γ-rays in the very high energy range. Situated in Namibia, it is composed of four Imaging Atmospheric Cherenkov Telescopes and gives a significant improvement in sensitivity and in accuracy of the reconstructed γ-ray parameters. First results on observations of pulsar wind nebulae are reported here. The binary system PSR B1259-63/SS 2883 has been detected in 2004 around the periastron, showing clear flux variations. The pulsar wind nebula around PSR B1706-44 has been observed and upper limits on its flux have been derived.
