The Deimos-1 Advantage

Landsat 7 Replacement

With a footprint more than three times wider than any Landsat mission and higher resolution multispectral imagery, Deimos-1 is an excellent substitute for Landsat 7 data with its well documented scan line failures.

Priority Tasking

Deimos-1 can be tasked at standard and priority levels in short time periods. This can facilitate comparisons of on-the-ground studies to remotely sensed data – a distinct advantage versus the set revisit times and footprints of the Landsat satellites.

No Blue Band

Deimos-1 does not collect imagery with a blue band though a technique has been developed to simulate true color images (i.e. red, green and blue) for applications requiring such.

Change Detection Studies

The footprint of Deimos-1 is much larger than any competitor satellite so its archive is robust and growing each day. This makes Deimos-1 an ideal sensor for land change studies, particularly those focused on forests, vegetation and agriculture.


Overview & HistoryDeimos-1 SpecificationsPricing

Deimos-1 was sent into space on July 29, 2009 propelled by a Russian-Ukrainian built Dnepr rocket from the Baikonur Launch Complex, Kazakhstan. This medium resolution satellite features 22-meter (m) resolution with 3 multispectral bands (i.e. green, red and near-infrared/NIR). Deimos-1 circles the globe at a maximum orbital height of 680 kilometers (km) collecting more than 5 million sq km of imagery per day with a footprint up to 625 km wide.

Since its launch, Deimos-1 has amassed a huge archive covering billions of square kilometers. Imaging the entire United States in just two weeks, Deimos-1 is considered by many to be a replacement for the failing but widely-utilized satellite, Landsat 7.
