The OHS Advantage

Hyperspectral Imaging

OHS offers greater insight into land use change with its 32 hyperspectral bands.

Extensive Archive Coverage

With eight satellites at 10-meter resolution, OHS collects and archives large swaths of the Earth’s surface daily.

Improved Image Classification

OHS’ thirty-two spectral bands will improve the fidelity and accuracy of your supervised and unsupervised image classifications.


Overview & HistoryOHS SpecificationsPricing

Zhuhay Orbita Aerospace Science and Technology, also known as Orbita, was founded in China in March of 2000. Orbita is committed to building a robust constellation of microsatellites, including hyperspectral, SAR, video and infrared satellites.

Their Orbita Hyperspectral Satellite (OHS) is actually a constellation of 10-meter (m) hyperspectral microsats launched regularly since April 2018. OHS fills a gap in the satellite market in terms of resolution and spectral capacity. Few satellites in orbit collect 10-m hyperspectral imagery, so OHS provides a unique regional perspective and greater coverage for the money with a 150-kilometer (km) swath width. These microsats are equipped with 32 spectral bands, offering better fidelity for spectral analysis.
