Description
Scheduled for launch in Q4 2026, the Gamma-ray Transients Monitor (GTM) is a science payload aboard the Taiwanese satellite Formosat-8B. Designed to detect GRBs and other gamma-ray transients within the 50 keV to 2 MeV energy band, the instrument consists of two detector units equipped with GAGG(Ce) scintillators and SiPMs to provide all-sky coverage. With an expected detection rate of 50 GRBs annually, the GTM provides a 3σ localization uncertainty for long GRBs of approximately 3 and 30 degrees for GRB fluences of 4×10-5 and 4×10-6 erg/cm2, respectively.
In this report, we will provide an update on the recent status of the GTM. The GTM was integrated on FS8B in June 2025 and has since been undergoing a series of environmental tests along with the satellite bus. Data taken in these tests will be used for tasks such as energy calibration, providing a baseline for future operation in space. The GTM Science Data Center will process data through GTM data pipeline to yield data products at different levels, which will be made available to the whole community. We are currently conducting final testing and verification.
