TANSO-FTS-2 Instrument

With a direct impact on billions of human beings every day, the Earth’s environment is among the most vital systems science investigates. L3Harris technology provides cornerstone data for that science with the Thermal and Near Infrared Sensor for Carbon Observation-Fourier Transform Spectrometer-2 (TANSO-FTS-2). The instrument takes global measurements of greenhouse gas concentration in the atmosphere and is the main payload of the Greenhouse Gases Observing Satellite-2 (GOSAT-2).

Advancing the Measurement of Greenhouse Gases

TANSO-FTS-2 provides very high signal-to-noise levels, very accurate onboard calibration and an agile intelligent pointing (IP) system that increases useful data collections in the presence of clouds.

The instrument measures greenhouse gas concentrations with extremely high accuracy covering the entire globe over a six-day revisit rate. This information is critical to climate monitoring and modeling. TANSO-FTS-2 measures carbon dioxide, methane and carbon monoxide simultaneously, allowing scientists to discriminate between natural and man-made emissions.

GOSAT-2 is a joint project of Japan’s Ministry of the Environment, the Japan Space Exploration Agency and the country’s National Institute for Environmental Studies. L3Harris developed the TANSO- FTS-2 under a subcontract to Mitsubishi Electric Corporation.
