Abstract
ARICA-2 (AGU Remote Innovative CubeSat Alert system -2) is a 2U CubeSat developed in AGU (Aoyama Gakuin University) in JAPAN. ARICA-2 was selected as the as the JAXA Innovative Satellite Technology Demonstration-4 and is scheduled for launch in Japanese fiscal year 2025. The mission objective of this satellite is to demonstrate the real-time alert system of sudden astronomical phenomena, such as gamma-ray bursts (GRBs). Observation of GRBs is challenging because it is difficult to predict location and time of occurrences and its extremely short duration. So, it is necessary to alert immediately for tracing observations of GRBs from the other observational equipment. ARICA-2 is the successor to ARICA, a 1U CubeSat launched by JAXA rocket in 2021. However, ARICA has never established the communication. ARICA-2 has three communication devices, two types of commercial satellite communication devices and a UHF (Ultra High Frequency) communication device. As ARICA did, ARICA-2 tries to demonstrate the real-time alert system by using commercial satellite network services. Commercial satellite communication devices are relatively inexpensive and easy to obtain. So, this demonstration is expected to promote research on sudden astronomical phenomena. Additionally, we decided to use UHF communication device, magnetorquers to attitude control system and Spresense, which is SONY’s low-power micro controller board, for on-board computer on ARICA-2 as a reflection of ARICA. And ARICA-2 is equipped with two types of gamma-ray detectors larger than that of ARICA.
