Abstract

JEM-EUSO is an international program for the development of space based Ultra High Cosmic Ray observatories. The program consists of a series of missions which are either under development or in the data analysis phase. The instruments consist of wide field of view telescopes, which operate in the UV range, designed to detect the fluorescence light emitted by extended air showers in the atmosphere. We describe the simulation software ESAF and show the physical assumptions done in it. We present here the implementation of the POEMMA, K-EUSO, TUS, Mini-EUSO, EUSO-SPB and EUSO-TA detectors in the simulation software ESAF.
