✦ Synopsis

The Large Area Air Shower (LAAS) group has been performing a network observation of extensive air showers (EAS) since 1996. Ten compact EAS arrays (stations) are scattered over a large part of Japan and operated independently and simultaneously. Each station has 4-12 scintillation counters and a Global Positioning System (GPS), which provides time stamps of EAS arrivals with an accuracy of 1~. The primary purpose of the network observation is to study large-scale correlations in ultra-high-energy cosmic rays, which are attracting much interest of the astroparticle physicists community in recent years. The present state of the network and some results from computer simulations are reported here.
