Abstract:
Optical sensors are now widely used as a cost-effective solution for space objects surveillance and tracking. ArianeGroup Helix network has been continuously providing optical data to its customers for more than 10 years. Initially focused on high-orbits surveillance, the system is constantly evolving to enhance its cataloguing capabilities.
Hence, the continuous expansion of the network leads to enhanced performances in terms of coverage and revisit time, covering LEO to GEO orbits data service provisioning. Helix is now covering 100% of the GEO belt with a revisit time less than 12 hours.
In addition, ArianeGroup keeps working on innovative sensors to improve the quantity and quality of SSA data, especially for LEO:
• A prototype SWIR sensor has been successfully tested to provide daytime data, and operational SWIR stations are currently under deployment in the Helix network, allowing an improved coverage in LEO
• Very wide field of view sensors have been developed, qualified and are integrated in the network for all orbit detections allowing to produce very large quantities of measurement data in LEO.
In this paper, we will describe the latest evolutions of the ArianeGroup system and its capacities, the newest sensors development and deployment, as well as the way forward to a comprehensive all-orbits data provisioning system.
