Objectives
The objective of the project is to design a cost-effective Optical Tube Assembly (OTA) with Nasmyth output for an 80cm telescope dedicated for optical communications.
While most solutions deploy today are based on a classical telescope design, AMOS is developing an optical tube designed specifically for optical communications. It allows for larger throughput at a lower cost and lead time.
With this project, AMOS is designing the OTA and the possible tools required for the manufacturing, integration and test of the 80cm tube. The goal is to work on a cost-effective design and to reduce the time of delivery.
Challenges
The following challenges are identified for the project:
-
Development of an optical antenna with higher performances compared to classical telescopes
-
To have a cost- effective design
-
To reduce the time from order to delivery by selecting components with lower lead time and simpler assemblies.
System Architecture
The optical tube is composed of following sub systems and components:
-
Optical Tube Assembly
-
M1 unit
-
M2 unit, including focuser
-
M3 unit
-
Tube structure
-
M1 cover
-
Interfaces for auxiliary telescopes
Plan
The project phases are:
-
Definition Phase;
Requirements & interfaces are developed resulting in a optical antenna baseline concept.
-
Technology Phase
Preliminary and detailed design of an optical antenna is performed with a PDR and CDR.
Manufacturing and validation of the OTA80 system.
Current Status
PDR achieved, CDR in progress.
