Satellite Subsystems



ESEN is engaged in satellite optical communication, satellite-ground optical communication and electro-optical satellite camera projects. Satellite subsystems that ESEN provides engineering support according to customer requests and needs could be listed as follows:

Optical Imaging Systems



Satellite Camera: ESEN performs activities in this area, which is in the intersection of satellite systems and imaging systems. A multispectral viewer design is currently being carried out for a ground observation satellite synchronized to sun that will be used for agricultural purposes and will operate in low orbit. For this purpose, customer needs were determined and band selection was made, resolution and scanning width were determined, appropriate sensor and optical requirements were determined and with preliminary design process, requirements were harmonized and a consistent design was achieved. Our studies towards multispectral viewer for aerial platforms continue.

Optical Communication Systems



1) In-satellite optical communication: In the satellite, there is a harness consisting of cables and connectors for power and data transmission between the equipment. This harness is a subsystem that adds weight and complexity to the satellite, which should be designed very carefully and which increases costs of the integration process. Removing the cables to be used for data communication within the harness will speed up and simplify satellite integration, reduce the weight of the satellite, and eliminate any malfunctions originating from connector during launch. For this purpose, research studies are being conducted on "free space optical link" which will allow communication between the equipment within the satellite without requiring the equipment to face directly at each other.

2) Satellite-Ground Optical Communication: The technology of optical communication established between satellite and ground is a critical technology that is currently owned by a limited number of countries around the world. The main advantages of this technology are as follows: Low Power Consumption, Low Mass and Low Volume which are all very critical for a satellite.
