SSTL reveals it is building a new sat after new 21AT deal

by | Feb 5, 2018 | China, Satellites

Surrey Satellite Technology Ltd (SSTL) has signed a GBP£25 million contract in Beijing yesterday with Twenty First Century Aerospace Technology Co., Ltd (21AT) to provide data from a new Earth Observation satellite (SSTL-S1) due for launch on PSLV in the middle of this year.

As the manufacturer, owner and operator of the SSTL-S1 satellite, SSTL will lease imaging payload capacity to 21AT for the lifetime of the satellite, designed to be in excess of seven years. The SSTL-S1 satellite will contribute sub-one metre resolution image data into 21AT’s existing TripleSat Constellation service, comprising three SSTL DMC3 satellites launched in 2015. The addition of the SSTL-S1 satellite will enhance both the revisit capability of the TripleSat Constellation and its efficient global high resolution remote sensing satellite data acquisition and operation services that support a wide range of existing successful user applications by 21AT’s domestic and overseas customers.

The design of the SSTL-S1 is identical to the present three satellites in the TripleSat Constellation that were launched in 2015. It has a mass of 450 kg and is capable of acquiring multiple targets in one pass, utilising spot, strip and mosaic imaging modes and 45 degree off-pointing agility for a range of applications including urban planning, agricultural monitoring, land classification, natural resource management and disaster monitoring. The very high resolution imager on board the spacecraft has been designed by SSTL and will provide sub-one metre resolution images in panchromatic mode and sub-four metre resolution images in multispectral mode, with a swath width of about 24km.

SSTL will lease imaging payload capacity to 21AT for the lifetime of the satellite.
