The EROS B Advantage
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 & History
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.
