Description	Demonstrate the real-time alert system of transient astronomical sources, such as gamma-ray bursts, using commercial satellite network services. The first 1U CubeSat ARICA, which had the same mission goal as ARICA-2, was successfully launched in 2021 by the JAXA’s Epsilon rocket No.5. However, communication with ARICA has yet to be established due to severe hardware issues. Therefore, ARICA2 is the re-challenging mission of ARICA. ARICA-2 has several different features compared to ARICA. First, a transceiver using amateur radio frequency is added to the commercial satellite network devices to communicate directly from the ground. Second, ARICA-2 uses Sony’s low-power board Spresense as an onboard computer. Third, the attitude control system using magnetorquer is installed to establish better communication with the commercial network satellites. Fourth, the size of a gamma-ray detector is 70 mm x 70 mm x 10 mm, which is larger by a factor of 200 in volume compared to ARICA, to enhance the detection rate of gamma-ray bursts. We plan to develop the engineering model (EM) in 2023 and perform thermal vacuum and vibration tests on the EM. We are targeting a launch in the Japanese fiscal year of 2024.
