Research Topics


This proposal addresses the demonstration of a low cost, two way datalink, the Oceanographic DataLink (ODL), capable of remote data collection and position reporting from small robotic vehicles. Specifically, the ODL will be integrated and demonstrated on Odyssey, the MIT Sea Grant Autonomous Underwater Vehicle (AUV). The proposed datalink uses existing C-band satellites and will support throughputs considerably higher than ARGOS, while providing a two way capability, and at a cost signifcantly less than currently charged by ARGOS. The ODL is comprised of a small transceiver and multi-element C-band patch antenna integrated into an Odyssey IIb AUV. The system will use a fixed broadbeam asymmetric antenna internal to the AUV housing and Odyssey will surface and drive towards the equator to position the antenna. A candidate architecture was developed in Phase I and will be implemented and demonstrated in Phase II. The demonstration will be in an operational environment.
