Polar lidar project presentation
- 1. Universal compact lidar for unmanned aerial vehicle (UAV). “Concern AGAT Research and Development Centre” Ltd. Tel./fax: +7-499-503-87-78 E-mail: AgatLtd@list.ru 105275, Russia, Moscow, Entuziastov shosse 29. • The project is intended for the development of competitive technology and appliance- based remote monitoring of the laser device, installed on unmanned carriers to operate in Polar region. The system is designed to study the ice, mapping shallow marine channels and obtain three-dimensional maps of temperature and pollution of water bodies. There is a laboratory model of the device. Two cruises have been conducted to test the design, methods of measurement and processing of the data. The structure of the technology which has been developed will also include: a program for automating the collection and processing of remote sensing, control both the complex storage system and a system of information visualization. The designed laser device provides wide applications on unmanned carriers especially for exploitation in the Polar region. The technology and hardware systems will be needed to address the commercial remote sensing tasks, as in the middle and polar latitudes, while working in the local, regional and global GIS (geographic information systems). The objectives of the project are: - The development and commercialization of products and technologies: Development and commercialization of competitive technologies and hardware design for express remote monitoring of ice conditions, mapping shallow marine channels, three- dimensional distribution of impurities and temperature in sea water, including the Polar regions. The compact laser device can be installed easily aboard unmanned carriers for the simple operations in the local, regional or global GIS - Applied research on the basis of the developed products and technologies: Conducting express remote monitoring ice conditions, mapping of shallow marine channels and three-dimensional distribution of impurities and temperature reservoirs, including the Polar arias.
