Commercial Data In Use
Satellite images are only as good as their resolution. The smaller the pixel size, the sharper the image. High-resolution satellite imagery tracks the changing human footprint across the globe, including rapidly growing cities, urban sprawl, and informal settlements. It also serves the basis for a global effort to map the world’s communities, such as OpenStreetMap, a platform where the imagery is used to digitize maps.
Satellite imagery helps to keep pace with technology growth, deliver diverse solutions and provide the most up-to-date high-quality data to various businesses globally. Today, the top 3 recognized high-resolution satellite imagery providers in the world are:
SI Imaging Services (SIIS) is the exclusive company provider of high-resolution satellite imagery (both optical and radar) across more than 110 countries around the globe. It was established in April 2014 as a subsidiary of Satrec Initiative (SI) and started operations as a satellite image and service provider. Later on, the company expanded its activities range to KOMPSAT operations and currently, contributes data to remote sensing applications and Earth observation industries for multiple purposes.
SIIS Sensors
Now SIIS is the exclusive distributor of the satellite imagery obtained by KOMPSAT-2, KOMPSAT-3, KOMPSAT-3A and KOMPSAT-5 satellites.
KOMPSAT 2
KOMPSAT 2 is an Earth observation satellite launched to obtain high-resolution imagery of the Korean peninsula. It operates in sun-synchronous low Earth orbit with a 5,5 – days revisit time. The satellite is equipped with a Multi-Spectral Camera (MSC) working in a strip mode operation to capture defined observation areas one at a time with a swath width of 15 km Nadir. The sensor delivers panchromatic as well as four-band multispectral imagery with a resolution of 1,0 m/pxl.
The System’s Key Features:
- it’s fitted with an optoelectronic linear pushbroom instrument with a single nadir-pointing telescope
- provides FOR (Field of Regard) of ±30º in pitch and up to ±56º in the roll direction
- supports observations in low-light conditions
KOMPSAT 3, 3A
KOMPSAT 3 and KOMPSAT 3A were launched to continue KOMPSAT 1 and KOMPSAT 2 missions accordingly. Both satellites are fitted with a pushbroom imager, AEISS (Advanced Earth Imaging Sensor System) with a spatial resolution of 0,5 m/pxl for KOMPSAT 3 and 0,4 m/pxl – for KOMPSAT 3A which was enhanced with IIS (Infrared Imaging System) to operate within the Mid-Wavelength Infrared region of 3 – 5 µm with high thermal resolution. The products obtained from the constellation are delivered as a specific data set: pan + four multispectral or four pansharpened bands.
The System’s Key Features:
- body pointing capability of ±45º into any direction
- ability to obtain sub-meter images with various imaging modes
- event monitoring capability along with single-pass stereoscopic observations
Applied Fields
Being the exclusive distributor of all the KOMPSAT imagery worldwide, SIIS supplies unique products which can assist in:
- natural disasters countermeasure activities planning
- volcanic and seismic activity prediction (due to temperature-sensitive sensors usage)
- water currents monitoring
- natural resources control as well as forestry management improvement
- maps designing
- data acquisition for GIS (Geographic Information Systems)
SpaceWill is one of the main providers of Earth Observation satellite imagery as well as geospatial technologies and information services authorized by the Chinese government for more than 10 years. The core business activity is to obtain and sell optical along with SAR satellite data, but it also deals with data processing, software and diverse solutions development; helps to boost construction of direct-receiving and virtual stations around the globe.
SpaceWill Sensors
SpaceWill is an operator of SuperView-1 or GaoJing-1 constellation which comprises four Chinese commercial remote sensing satellites. The whole constellation is planned to be completed by 2022. It will include 16 optical satellites, 4 higher resolution satellites, 4 SAR (synthetic aperture radar) satellites and a fleet of satellites with video and hyperspectral cameras.
The SuperView Program
The SuperView program, also called “16+4+4+X”, was launched in 2016 with SuperView-1 01 and Superview-1 02 and followed by SuperView-1 03 and SuperView-1 04 in 2018, operating in the same orbit phased 90° from each other, at an altitude of 500 km. These were the first “very high-resolution” Earth observation spacecraft, produced in China, collecting data with the spatial resolution of 0,5 m/pxl.
The System’s Key Features:
- works in 4 modes: stereo imaging, long strip, multiple strips collect, multiple point targets collect
- collects up to 700,000 km2 of imagery daily
- stands out for agility, efficiency, and responsiveness
Applied Fields
The imagery collected serves multiple purposes:
- defense and intelligence
- land and forestry management
- high accuracy mapping
- security and maritime programs
Airbus
Airbus Defense and Space is the second largest space company and one of the biggest manufacturers of satellites for Earth observation, navigation and telecommunication purposes. This division was formed in 2014 when the European Aeronautic Defense and Space (EADS) was restructured. Airbus Defense and Space GmbH comprises the former Airbus Military, Astrium and Cassidian divisions and now is in the top ten companies working for the defense.
Airbus Sensors
Currently, Airbus DS obtains and offers for both commercial and private use high-resolution satellite imagery from the following satellites: Pléiades 1A and 1B, SPOT 5, 6, 7 among others.
Pléiades 1A, 1B
Pléiades (1A and 1B) operate in the same sun-synchronous orbit at 694 km with global coverage in 26 days and daily revisit to any place on Earth. Both satellites are equipped with high-resolution optical sensors providing multispectral and panchromatic products with a resolution of 0,5 m/pxl and footprint at 20 kilometers.
The System’s Key Features:
- along-track stereo and tri-stereo images within an 800-km-wide ground strip
