Project Idea
The Expandable Radio Observation System (EROS) introduces a novelsolution to a longstanding limitation in conventional radio telescopes: the ak or distant cosmic signals due to limited collecting area, resulting infixed, large-diameter dish. Such systems face challenges in detecting the w e reduced sensitivity and angular resolution. Our proposed design features a telescopic sliding-panel mechanism, inspired by the folding mirror concept of the James Webb Space Telescope (JWST). llecting area, resulting in a 2.25× improvement in sensitivity and an apprThis mechanism allows the dish to expand from 5 meters to 7.5 meters using lightweight yet structurally stable panels, driven by compact electric motors. The expansion increases the effective c ooximate 33% enhancement in angular resolution. Simulation results demonstrate improved signal clarity, greater temporal stability, and higher signal-to-noise ratio (SNR), enabling detection of weaker signals previously undetectable by smaller telescopes. EROS offers an efficient and low-maintenance solution for research and educational applications by combining high-performance radio observation capabilities with practical and scalable mechanical design.
01
The Beginning
The idea started from the limitation of the Fixed Large-Diameter Dish in conventional Radio Telescopes, which limits Sensitivity and Angular Resolution. We proposed an Expandable Dish that can change its size when needed.
02
The Idea
EROS provides an expandable telescope that grows from 5 m to 7.5 m, improving Sensitivity by 2.25× and Angular Resolution by approximately 33%.
03
The Experience
We started with an Expandable Dish concept inspired by JWST, then designed a Telescopic Sliding-Panel mechanism using lightweight panels and Electric Motors. The design was tested through Simulations, showing improved SNR and signal clarity.
