Abstract:

Optical sensors are now widely used as a cost-effective solution for space objects surveillance and tracking. ArianeGroup Helix network is entirely based on optical visible sensors and can provide accurate angular data on a wide range of space objects.

However, classical optical observations of orbital objects are usually limited to nighttime. Consequently, favorable spans of time for observations are limited, especially for objects on low Earth orbits, which are often situated in Earth shadow with respect to the station. Therefore, the ability to observe at daytime would allow the extension of the observing periods and multiply the observation opportunities. In 2021, ArianeGroup built a prototype of short wave infrared (SWIR) sensor that was used for the first tests and allowed the successful detection of objects at daytime. After this proof of concept, ArianeGroup kept working on the optimization of the station and its associated algorithms, so as to enhance the performances.

In this paper, we will describe the configuration of the ArianeGroup station, the results obtained and the way forward to an industrialized operational station that will be integrated in the existing network.
