EOS (Singapore earth observatory) is trying to develop a rapidly deployable system to collect data near the volcano crater. Considering the geological factors on the volcano, it is essential that the telemetry of this system should be able to transmit data over 3km distance. This project focuses on how to make such a telemetry system using existing equipment of the shelf while keeps the cost as low as possible. The design of this telemetry should minimize the energy consumption and optimize flexibility of the whole system. Firstly, the report translates the requirements into technical aspects. It takes energy consumption, environmental attenuation and system compatibility into consideration. A research and comparison of the existing products are made to select the telemetry that fits the best. The proposed telemetry uses 2.4Ghz Wlan device and Xbow IRIS radio and MIB600 interface board. Both IRSI radio and Wlan radio have been tested under similar surrounding conditions compared with the one near volcano crater. A feasibility study is done using data collected to determine its viability under real working condition. The results showed that the proposed telemetry solution integrates well with the whole system and is expect to deliver good performance.
