INDEMN is a program built in-house for predicting the risk related to on-orbit collisions. It is highly flexible and provides long term analysis for satellite operators and insurance companies. The code was validated with the Inter-Agency Space Debris Coordination Committee reference case. and the original method was published in a peer-reviewed journal.

A state-of-the-art simulation tool of the orbital environment…

INDEMN allows the user to predict a risk profile for a given satellite mission or for a constellation project (6 months – 60 years), with an optimized user experience. We make use of the latest updates of the space-track.org database and state-of-the-art statistical models released by academic research. Le risk computation is made with algorithms developed in-house. The code was benchmarked on simplified cases with seven other simulation codes developed by Space Agency throughout the world.

… that is suitable to today and tomorrow’s needs in Low Earth Orbit

The launch of several constellations of several hundreds or thousands of satellites in a near future will have a critical impact on the orbital environment. This is a major concern for the the whole space community, as emphasized by the intensive studies carried out by space agencies. These studies have stressed out the role of some parameters at constellation level, particularly the typical distance in altitude between satellites, the de-orbitation scenario, and also at spacecraft level, such as the reliability of pressurized tanks, batteries, and de-orbitation devices. Given the new production modes that are developed throughout the space industry in order to scale up the production lines, the risk of product failures in series in uncertain and expected to be high. Product failures in series may have critical consequences on the profitability of the business model for constellation operators, and may prevent any space operation in the future if some low earth orbits become too polluted. INDEMN was designed to simulate this kind of scenarios and identifies in what range of parameters a constellation should operate. The model allows the user to integrate several constellations in the environment scenario.

CALM allows satellite operators to treat collision warning messages automatically, hence minimizing the risk and maximizing the utilization of the spacecrafts.

Data treatment for short term debris forecasts

CALM (Collision Avoidance by Limited Maneuver) is based on a machine learning algorithm that provides accurate orbital data with quantified uncertainties. The program is trained with a number of accurate orbital data and relies on our own telescope obsevations. This algorithm, when coupled to state-of-the-art orbit propagators and to the NORAD database, provides many orbital data for debris that are suspected to be dangerous and to reduce the uncertainty on their positioning at the time of closest approach.

A key to Space Traffic Management

As the number of low Earth Orbit satellites increases and that their price goes down, the ground based space surveillance network cannot cover the whole set of active satellites anymore. On some crowded orbits, the number of conjunction messages can be as high as 100 per day and per satellite, and the collision avoidance maneuvers remain costly (broadcast interruption, lifetime reduction, ground operation).

We use the space observation data that is available by our scientific partners with our data processing pipeline to cover all orbits and deliver the relevant data to our customer in near real time. This data allows operators to make the right decision whether they should perform a collision avoidance maneuver or not.

DRYADE is a concept of systematic on-orbit space debris collection based on bio-mimicry.

Decisive technology for a sustainable economy in space

The space sector will continue to pave the way both in terms of technological innovation and sustainable development. One of the main hurdles to space debris collection and more generally to on-orbit services is the ability to perform automated non-collaborative rendezvous. We are currently deploying in partnership with Ecole polytechnique (Palaiseau, France) on computer vision algorithms dedicated to the final phase of the capture, when the chaser is in relative navigation mode.

A shift in the business model of space

Current business models across the space industry are based on systems that are altogether very costly, dedicated to a very limited number of tasks, and disposable, since no intervention is possible during their lifetime to fix an issue on spacecrafts. This model has to change with the rise of a number of emerging on-orbit services such as space debris management, battery loading, refueling, or spare parts replacement. Comparison with other more mature sectors, such as the car industry, and studies carried out by NASA suggest that in-orbit services will generate 3 B€ revenue each year in 10 years. Because time to market will be key, we invest our time and money to develop cutting-edge technologies and concepts in the field.
