iSIM-90 is the lightest and most compact optical payload of the iSIM family. It has been purposefully designed to fit 12U/16U CubeSat platforms, while keeping a high performance to mass ratio.

The payload includes the optical front-end as well as state-of-the-art CMOS matrix detectors and an electronics subsystem for payload management and control. With a total mass below 6kg, iSIM-90 can achieve ground resolution down to 1.65m from an altitude of 500km. It covers the Visible & Near Infrared (VNIR) spectral range, offering both panchromatic and multispectral imaging capabilities according to the user's needs.

With a total mass below 6kg, iSIM-90 can achieve a GSD <2m from an altitude of 500km. It covers the Visible & Near InfraRed (VNIR) spectral range, offering both panchromatic and multispectral capabilities according to the user's needs.

The optomechanics is configurable to provide single or dual channel, for more spectral bands and more swath.

The Super Resolution algorithm developed by SATLANTIS can improve the spatial resolution by a factor of at least 2.5, beyond the instrument's native resolution.

Furthermore, a newly developed Short-Wave Infrared (SWIR) option is also available for this payload, with an extended spectral range up to 1700nm. iSIM-90 payloads are customizable both in terms of spectral range and number of channels, allowing imaging in VNIR and SWIR simultaneously in dual channel configuration, or any of the two (VNIR/SWIR) in a more compact single channel configuration.
