A decade of disaster monitoring

Celebrating 10 years of success, members of the Disaster Monitoring Constellation (DMC) and representatives from 12 different countries, the European Space Agency and six UK government departments met up in London last week for the 13th DMC Consortium Meeting. The UK Space Agency, SSTL and DMC International Imaging (DMCii) jointly hosted the day – the theme ‘Vision for the next Decade of the Disaster Monitoring Constellation’.

DMCii works with the world’s space agencies and the United Nations (UN) within the International Charter: Space and Major Disasters to provide multi-spectral and panchromatic optical imagery during disasters. The constellation responds to disasters frequently and has played an important role responding to disasters such as the Asian Tsunami (2004), Hurricane Katrina (2005), and the UK floods (2007). The constellation has also very rapidly supplied imagery for the recent earthquake in New Zealand.

SSTL’s cost effective approach to satellite design lowered the price tag of Earth Observation to the point where governments and organisations throughout the world could own an independent satellite, providing cost effective sovereign remote sensing capability with shared ground segment, image processing and commercial distribution – and play an essential role in international disaster response.

What’s smaller than small? - Nanosats

Innovation

During the past 25 years building satellites, SSTL has been instrumental in changing the economics of space for customers ranging from established space players such as ESA and NASA through to establishing new space programs for nations taking their first steps in space. With the incredible advances in engineering and electronics during this time, smaller satellites are increasingly catching up with their larger counterparts. The question technology guru Shaun Kenyon from Mission Concepts is now asking himself is: What can we do with today’s 50kg satellites and how does that compare to smallsats?

The answer to that question is simply; a lot! Known as nanosatellites (nanosats), these low mass satellites (for the purpose of this discussion let’s assume less than 50kg) are capable of a broad range of applications, including scientific research and Earth observation. The laws of physics makes some things more challenging though – for example preventing their use for applications such as high resolution imaging because a camera must maintain a minimum size of aperture to deliver such resolution.
