“…In EUSO‐TA and EUSO‐Balloon experiments, the time difference was constant and about 3600 GTUs (it depended on each subsystems startup delay), so that a 5000 GTU value was chosen to allow for some jitter. This was due to the electronics of the subsystems, in particular to the lack of a command to reset the GTU counters on one of the two subsystems. In the EUSO‐SPB software, the reset command has been added in the updated firmware of both the CLKB and the CCB; therefore, the subsystems have a time difference always and exactly equal to 0 GTUs, with no appreciable jitter.…”

In this paper, the flight software architecture of the EUSO-SPB mission is described. The JEM-EUSO program aims at developing an advanced large space-borne UV telescope designed to detect ultra high energy cosmic rays. In this framework, the EUSO-SPB experiment is the third pathfinder mission of the JEM-EUSO program, the second that has been launched on a stratospheric balloon to test the technological readiness of the detectors and to carry out some preliminary scientific observations. The EUSO-SPB software has a modular structure conceived to control all the instruments and the ancillary subsystems, to acquire data, and to manage data transfer to ground. System programming in C and C++ languages and Bash scripts have been used to implement and run the modules. The software runs on the data processor, an onboard computer that communicates with several payload blocks, the UV sensor, and the synchronization and time tagging board. The control software module controls all the subsystems, provides communication to ground through the NASA telemetry or the Internet, runs the acquisition control and download software, and manages the execution of the acquisition software. The acquisition software module directly operates the subsystems for the data acquisition activity. The acquisition control and download software module runs the acquisition software upon request of the control software and transfers scientific data to ground. The software system performed as expected during the flight on April 2017. KEYWORDS cosmic rays, EUSO, flight software, SPB, stratospheric balloon, UHECR THE JEM-EUSO EXPERIMENTSThe JEM-EUSO * program 1,2 aims at developing a large space-borne UV telescope able to detect the ultra high energy cosmic rays (UHECRs). The very wide field-of-view telescope is conceived to look down from space toward the Earth to detect the fluorescence photons emitted by the cascades of particles produced by the interaction of an UHECR with the *EUSO is the acronym of Extreme Universe Space Observatory, whereas JEM is named after the Japanese Experiment Module, the module of the International Space Station where the UV telescope was initially designed to be installed. 524
