What is hyperspectral satellite earth observation (EO)? Hyperspectral imaging (HSI) is a technique that divides the electromagnetic spectrum into many contiguous, narrow spectral bands. Unlike traditional optical imagers, which capture light in the red, green, and blue (RGB) bands, or even multispectral sensors that capture data in up to 36 broad spectral bands, hyperspectral sensors capture data in hundreds of narrow bands.

The role of satellite imagery in conflict zones Satellite imagery has proven crucial in assessing the scope of destruction in Gaza. Through the use of high-resolution Earth Observation technology, experts have been able to track and analyze damage across large areas, providing an accurate and unbiased perspective.

Maxar’s operational satellites Maxar operates a fleet of high-performance satellites that deliver imagery essential for intelligence, mapping, and monitoring applications worldwide. Here are the key operational satellites: WorldView-1 (Launched 2007) Capabilities : High-resolution panchromatic imagery Resolution: 50 cm panchromatic WorldView-2 (Launched 2009) Capabilities: High-resolution panchromatic and multispectral imagery Resolution: 46 cm panchromatic, 1.

Although both constellations and clusters refer to groups of satellites, they serve different purposes. A satellite constellation refers to a network of satellites on similar orbits that collaborate to achieve a common goal, such as global communication or Earth observation. These satellites are strategically positioned to avoid overlapping coverage and interference.

Sentinel-2C Mission Overview Launched on September 5th, 2024, Sentinel-2C is part of the European Union's Copernicus Programme—an extensive network of Earth-observing satellites designed to monitor the environment, land use, and coastal waters. However, once a month, Sentinel-2C shifts its focus from Earth to the Moon for a "Moon calibration" procedure. This routine calibration is critical for ensuring the radiometric accuracy of the satellite's instruments.

BlackSky expands into space domain awareness through strategic partnership with hEO HEO specializes in NEI and space analytics . The newly established partnership integrates BlackSky’s satellite constellation into HEO’s sensor network. This collaboration enables capturing space objects data, especially over the middle latitudes of Earth, using previously unused satellite capacity when satellites are passing over oceans or during eclipse phases.

Near Infrared: A key tool for vegetation and crop health monitoring The Near Infrared band is particularly useful in agriculture for crop health monitoring and assessing the overall condition of vegetation. In general it is used for assesment of the condition of vegetation. It is possible due to NIR’s strong correlation with the plants’ chlorophyll level. Healthy plants with high levels of chlorophyll are able to reflect the NIR light very efficiently.

New satellite images expose the dramatic landscape of flooded areas Satellite maps, available in the OnGeo Intelligence Satellite Image Report , precisely depict the flood-affected regions. The extent of the flooded areas significantly exceeds previous estimates, further emphasizing the importance of this data for effective crisis management.

Passive and active Earth observation satellites Among the different types of sensors monitoring the Earth from satellites the most important distinction can be drawn between optoelectronic and radar satellites . The optoelectronic satellites are equipped with passive sensors in many ways similar to cameras that we use every day taking pictures with our smartphones.

New Addition to Copernicus Fleet Promises Enhanced Climate Change Monitoring and Environmental Management Sentinel-2C joins its predecessors in the Copernicus constellation, reinforcing Europe's capacity to monitor environmental changes, support agricultural practices, and aid in disaster management. This launch ensures the continuity of vital data streams that have become indispensable for addressing global challenges.
