The LAGO project aims at the detection of high energy photons from GRBs using the single particle technique in ground based water Cherenkov detectors. To reach a reasonable sensitivity, high altitude mountain sites have been selected and detectors are in operation in Mexico (Sierra Negra, 4650m a.s.l.) and Bolivia (Chacaltaya, 5300m a.s.l.). We report on detector calibration and operation at high altitude, search for bursts in 4 months of preliminary data, as well as search for signal when satellites report a burst.
