SKY Perfect JSAT and ITOCHU Announced Commencement ofSAR Satellite-Based Oil Spill Monitoring Service to Qatar
SKY Perfect JSAT Corporation (Headquartered: Minato-ku, Tokyo; Representative Director, President & Chief Executive
Officer: Eiichi Yonekura; hereinafter "SKY Perfect JSAT") and ITOCHU Corporation (Headquarters: Minato-ku, Tokyo;President and COO: Keita Ishii; hereinafter “ITOCHU”) announced today the commencement of Synthetic Aperture Radar(SAR*1) satellite-based oil spill detection service to the Qatari Ministry of Environment & Climate Change (hereinafter “QatariMECC”).
Around the world, about 2,000 oil spill accidents caused by oil tankers have been reported since the 1970s*2. Especially in
the Persian Gulf coast including Qatar, where many multi-national vessels navigate, countermeasures for oil leak have beenstudied for many years. From perspective of environmental protection, it is important to detect and deal with such oil leakfrom a vessel as early as possible before it reaches the shore.
This service is provided in joint partnership with Kongsberg Satellite Services, AS (Headquartered: Tromsø, Norway,hereinafter “KSAT”), a leading provider of global ground network and satellite-based earth observation services and uses
SAR satellite imagery downlinked at KSAT and its partners' ground stations to detect offshore oil leaks. Following suchprocess, analysis is performed in combination with AIS (Automatic Identification System) information*3 transmitted fromvessels, and the vessel with the oil leak can be identified.
As result of joint proposal activities to the Qatari MECC by SKY Perfect JSAT and ITOCHU, service features such ascapability to observe wide sea area by using combinations of various satellites and provision of daily and emergency
observation reports were evaluated by the Qatari MECC and led to this service commencement. This is the first case in which
the two companies jointly provide satellite data-based analysis service overseas. In addition to continuously providing thisservice to Qatar, we plan to expand this service to other countries and companies in sea areas where there is similar demand,protecting the marine environment and preventing damage at important facilities such as desalination facilities and power
plants in coastal areas from oil leaks.
SKY Perfect JSAT and ITOCHU will continue to pursue the enhancement of corporate value by contributing to thesustainability of society and the environment, solving social issues through business activities and aiming for sustainablegrowth.

SAR: Synthetic Aperture Radar. A radar that obtains an image of the earth surface by irradiating the ground surface with microwaves and analyzing the signalsthat are reflected back. It is characterized by being able to penetrate clouds and volcanic smoke, and to observe the situation of the ground surface regardless of dayor night or weather.

AIS information: Information such as vessel’s identification code, name, location, speed, course, destination, etc., transmitted from its Automatic Identification

System. From perspective of maritime safety, such as collision prevention, vessels navigating the sea are obliged to exchange such voyage related information with1 / 2

each other, and to be installed on certain vessels as stipulated by the SOLAS Convention (Convention for the Safety of Life at Sea). The purposes are (1) to identifyvessels, (2) to assist in tracking targets, (3) to facilitate the exchange of voyage information, (4) to provide information useful in collision avoidance, (5) to reduceship reports by radiotelephone. For this reason, the AIS device must always be turned on, even when the vessel is anchored, and continuing to transmit the vessel's
own information so its location can be determined at all times.
