The Surrey Satellite Technology Limited (SSTL) S1-4 Satellite was developed with Airbus Defense & Space. Data capacity from SSTL S1-4 is leased to several entities, and is also delivered as a sub-1meter imagery service known as Vision-1 for providing very high resolution used for applications including defense, security, maritime and agriculture.
The SSTL S1-4 was deployed into a sun-synchronous orbit at an altitude of 583 km and an inclination of 97.5°. It has an LST of 1030 on a descending node with an orbital period of 96.2 minutes. The revisit capacity is daily to 8 days, depending on the latitude of the area of interest.
Imagery from the Vision-1 service provides imagery in one panchromatic band and four multispectral bands for a 20.8 km swath width at nadir with a spatial resolution of 0.9 m and 3.5 m, respectively. The multispectral bands consist of one near infrared (NIR) band, and three visible bands – red, green and blue.
The SSTL S1-4 Satellite was deployed into a sun-synchronous orbit at an altitude of 583 km and an inclination of 97.5°. It has a Local Time of the Descending Node (LTDN) of 1,030 hours with an orbital periode of 96.2 minutes. The revisit capacity is one to eight days depending on its latitude.
The satellite was launched on September 16th, 2018 on board the Polar Satellite Launch Vehicle (PSLV), operated by ISRO, from the Satish Dhawan Space Centre in Sriharikota, India.
Airbus Defense & Space
Airbus Defense & Space is a division of Airbus Group responsible for defense and aerospace products and services. The division was formed in January 2014 during the corporate restructuring of European Aeronautic Defense and Space (EADS) and comprises the former Airbus Military, Astrium and Cassidian divisions.
Airbus Defense & Space is presented in dozens of countries on six continents and is a world-leading player in the space industry and Europe’s No. 1 in Defense and Space. Their spacecraft manufacturing division is designer and builder of over 100 communications satellites for a vast range of applications, such as communication-, weather-, Military & Government Satellites.
Since 2021 the company is providing Earth Observation services with Pléiades Neo constellation of six 30cm optical resolution LEO satellites. Each satellite will be adding half a million km2 per day at 30 cm resolution to Airbus’ offering. These images will be streamed into the OneAtlas on-line platform, allowing customers to have immediate data access, analytics and correlation with Airbus’ unique archive of optical and radar data. The satellites are built in-house and launched by major launch operators.
