The Japan Aerospace Exploration Agency (JAXA) is considering the possible deployment of early warning satellites to detect ballistic missile launches.

JAXA is planning to study and conduct experiments and tests involving the installation of two-wavelength infrared (IR) sensors, which would be then installed on an Advanced Optical Satellite-3 (ALOS-3) by 2020.

The tests will then be conducted until 2024, wherein the Japanese government will decide if it would launch an actual early warning satellite into orbit.

The ALOS-3 satellite is an earth observation satellite built in Japan, and can be launched into space by the Mitsubishi Heavy Industries H2A rocket.
