Recently, aerial remote sensing in coal Bureau held a news conference in Beijing, the introduction of inertial navigation system of the IMU and DGPS differential global positioning system, E Bird inspection system to measure three-dimensional spatial information systems and SAR remote sensing applications, such as four new technologies 3S and products, this is the coal of independent innovation in the aircraft made another major breakthrough.

IMU inertial navigation system and DGPS differential global positioning system to solve in practice the INS key issues and flight data handling issues related to application Tongchuan in Shaanxi 1:500,1:1000,1:2000 mapping scale topographic maps China has achieved satisfactory results, and adopted the Li Deren Identification of academicians and other experts. The Group believes that to promote the study of the IMU / DGPS-assisted technology in the large-scale digital aerial application, in the domestic leading level.


E Bird inspection system for oil, natural gas, electricity, telecommunications and other industries城市管网development of real-time monitoring, playback tracks, data sampling, wells and pipeline mapping and safety of the latest scientific and technological achievements of early warning. It will receive GPS location information and the entry of inspection data (such as the pipeline name, leaking, excavation, erosion, vandalism, etc.), through the network transmission to the relevant geographic information systems, management of geographic information systems through an intuitive , real-time to grasp the work of patrol officers and field line (or equipment) the operation of a visualization operation and production management of information technology has greatly enhanced the speed of troubleshooting, reducing management costs. The system has been the national utility model patent.


Three-dimensional spatial information system to measure coalfield resources for exploration, development of specialized R & D real three-dimensional geological model editable. The system uses two-dimensional, three-dimensional framework for model integration in high-precision three-dimensional model, the realization of a two-dimensional and three-dimensional graphics and flexible conversion, space observation and spatial analysis can reproduce the true coal, roadway, drilling and its relationship with ground of the spatial relationships between objects.


SAR remote sensing application system is the "863 Program" high-performance air SAR remote sensing application system sub-project issues, the focus of national investment and to develop a model of the mapping of Earth observation technology. The system can penetrate clouds, smoke and dust of the ground vegetation has a penetrating, you can quickly access a large area of the three-dimensional location of features and small deformation, in particular, the traditional optical sensors for imaging of the region difficult. The successful development of its powerful advanced airborne InSAR (Interferometric Synthetic Aperture Radar) system of running the business, not only can extract digital elevation models, and as a measurement system for digital orthophotos, DLG's high-tech means 1.
