Abstract
PETREL's science goal is to detect transient phenomena in ultraviolet objects and to reveal the nature of explosive phenomena in the universe through multi-messenger observations. PETREL is equipped with an 8cm refractor telescope and a COTS BI-CMOS detector behind an optical blind filter. Expected sensitivity is 20 mag(AB) for a 50 deg^2 field of view at a wavelength of 250-300 nm with a 30 minute exposure. To perform multi-messenger observations, the high-performance OBC automatically analyzes the acquired images and searches for transient sources on board. The coordinates and magnitudes of transients are transmitted to the ground within minutes via a commercial real-time communication network. The overall system of the PETREL satellite, with a particular focus on ultraviolet astronomy missions, will be presented.

Associate Professor, Department of Physics, Tokyo Institute of Technology. His main research interests are high-energy astrophysics and aerospace engineering. Since 2003, he has been engaged in space demonstrations using nano-satellites. In 2016, he proposed a micro-satellite-based ultraviolet transient survey. For this mission, he developed a high-performance star tracker, high-speed OBCs, and an RF transmitter for real-time communication for small satellites. These devices were demonstrated on the 50 kg satellite Hibari launched in2021. The team then moved on to the ultraviolet satellite mission.
