Just the old presentation from Hemera System, back in 2012

1. This platform aims at providing a new capacity for space
application based upon a low cost and very high flexibility. It
will hence be suitable to many applications, focusing on highly-
autonomous behavior of the platform evolving within a swarm.
This will bring precious knowledge in the field of distributed
system behavior in space.
The main goal of Hemera System is to offer space capabilities
at the lower cost, bringing it down to 100,000 euros for a full-
featured satellite, 10 to 100 times less than its current equivalent.
A functional broker over a standard linux OS is managing the
communication between the different applications. Emphasis is
put on the development of a SDK and on an integrated simulator
to encourage innovative applications in numerous fields. Providing
the right system software is the key of Hemera System’s strategy.

3. EAGLE Is an observation satellite
based on Hemera System’s platform.
Initially dimensioned as a 20cm cube, once deployed it measures 40cm in
flight direction. It provides optical capabilities with a resolution down to 5
meter per pixel prior to any image processing. As a 3-axis controlled platform
with precise attitude determination thanks to its star trackers, it provides
pointing capacities for all targets.
The bus provides high computational power in order to allow on-board
processing capabilities equivalent to a small notebook. This enables
simple pre-processing of images, like cropping or resizing as well as more
advanced features like pattern recognition. It allows a new range of auto-
nomous applications for LEO satellites as the one demonstrated in the
prototype being maritime surveillance using optical and RF tracking. The
spacecraft can also automatically reschedule a picture if the quality of the
taken image is not satisfying (e.g. due to weather influences).
Leasing of onboard computing time will be available to third parties
so that new space applications can thrive at the cost of a web server.
Hemera System provides a web interface for images ordering giving the
customer all the time opportunities possible as well as some recommen-
dations given the situation (weather forecast, viewing angles…). The ini-
tial cost is planned to be at 1 euro/km2 with the prototype while aiming at
bringing down the cost to 0,01 euro/km2 with the next fully commercial
generation. In the future, a constellation of satellites will allow the medium
resolution coverage of any place on Earth within a window of 30 minutes.
