SSTL reveals 1-metre resolution images from mini-satellites

UK satellite manufacturer SSTL has released the first images acquired by its new mini-satellite constellation. 

The DMC3/TripleSat constellation, launched in July aboard an Indian PSLV rocket, provides a 1-metre resolution and covers a swatch of 24km.

The images released today were captured in late July and early August and show the Olympic Stadium in Athens, Greece, and the airport in Sydney, Australia.

The three satellites, the most capable to have been developed by SSTL (Surrey Satellite Technology Ltd), circle the Earth in a Sun-synchronous orbit at an altitude of 651km. They follow the same path with intervals of 120 degrees between them.

Thanks to their ability to look 45 degrees sideways, the three satellites, weighing 45kg each, will be able to look anywhere on Earth at least once per day and provide the best combination of spatial resolution and time resolution, SSTL said.

A Chinese Earth observation firm, the Twenty First Century Aerospace Technology Company Ltd (21AT), has leased 100 per cent of the imaging capacity of the DMC3/TripleSat constellation for the next seven years.

Data from the satellites can serve a wide range of applications from urban planning to crop monitoring and intelligent management.

SSTL has already manufactured a fourth SSTL-S1 earth observation satellite for another customer and has a production line ready to deliver further satellites of this type. In agreement with 21AT, future satellites may have the opportunity to join the TripleSat Constellation.
