WNISAT 1 (Weather News Inc. Satellite 1) is a nanosatellite for north arctic routes and atmosphere monitoring. The project is started from the commercial objects between Weathernews and Axelspace. The object of the WNISAT-1 mission is monitoring of the Northern sea routes and of the CO2 content of the atmosphere.

The 10 kg satellites is built on a 27 cm cube structure and is three-axis-stabilized.

Two cameras cover a 500 km × 500 km area. The cameras operate in two bands: visible band and near-infrared. 10 photos per day can be downloaded to the ground station. The time gap from the shooting to the downloading is expected to be half day.

For measuring the CO2 content, the satellite emits laser beams at wavelengths of 1556 nm and 1570 nm. The lasers illuminate an area of about 10 km diameter. The reflected light is detected by the satellite.
