The EROS B Advantage

Reasonable Pricing
EROS B data is priced below all other high resolution satellite imagery for both archive and tasking orders.

Rush Tasking
When new collections are placed at rush priority, the first attempt is guaranteed within 5 days of order activation.

Stereo Pairs & Triplets
EROS B can be tasked for new collections of stereo pairs and triplets. Triplets are useful for creating accurate elevation models in areas with extreme topographic change and/or tall structures that obscure the land below.

Nighttime Tasking
If you need high resolution nighttime imagery collected, EROS B is your only choice. There is seasonal variability to the nighttime imaging periods in extreme latitudes which are detailed in this chart.

Overview & HistoryEROS B SpecificationsPricing

The second panchromatic satellite owned by ImageSat International, EROS B was launched into orbit on April 25, 2006 from Svobodny Launch Complex, Russia. This high resolution satellite orbits the Earth at a height between 516 and 524 kilometers (km), collecting black and white imagery with an average resolution of 70 centimeters (cm). EROS B is the only high resolution satellite that can be tasked to collect nighttime imagery. This data has a wide array of uses including urban sprawl measurements, light pollution detection and population estimates.
