Theia Earth observation imager

 

ETIS homepage

THEIA is a scientific-grade multispectral Earth Observation Imager for nanosatellites.  The goal of the imager is to provide data suitable for quantitative remote sensing studies. This can enable a cost-effective solution for providing radiometrically accurate data at a high temporal resolution using multiple EOIs in orbit. The instrument takes images in two user-chosen predefined spectral bands. Post-launch calibration is achieved using a calibration module capable of producing dark and flat frames. Moreover, this is achieved while adhering to the CubeSat standard, fitting inside 1U, and weighing less than 600 g. 

Specifications:
Spectral range: 200 nm - 1100 nm
Volume: 1U compatible (0.6 U)
Mass: 600 g
GSD without smearing (@ 650 km): 35 m
FOV: 2.7 deg x 2.1 deg
Resolution: 943 x 733 px
Spectral bands: 2 (user chosen)

Start: 08.01.2018
End: 30.11.2022

Financed by: European Space Agency Industry Incentive Scheme and the General Support Technology Programme
