Since its contribution to the Spot5 satellite program in 1997, Sonaca Group has been involved in applications dedicated to terrestrial monitoring. In this context, the company is working on the development of a high altitude system platform capable of prolonged observation of a specific area (satellites do not have this capability). This is a truly global project, from the design to the production of the platform, including its commissioning throughout the world and the provision of analyzed data for end customers. The services cover the surveillance of local sites, local land management and pollution control.
