The U.S. Army Corps of Engineers (USACE) Advanced Modeling Object Standard (AMOS) has been developed by the CAD/BIM Technology Center for Facilities, Infrastructure, and Environment to establish standards for support of the Advanced Modeling process within the Department of Defense (DoD) and the Federal Government. The critical component of Advanced Modeling is the objects themselves- and either make the modeling process more difficult or more successful. This manual is part of an initiative to develop a nonproprietary Advanced Modeling standard that incorporates both vertical construction and horizontal construction objects that will address the entire life cycle of facilities within the DoD. The material addressed in this USACE Advanced Modeling Object Standard includes a classification organization that is needed to identify models for specific use cases. Compliance with this standard will allow users to know whether the object model they are getting is graphically well developed but data poor or if it does have the data needed for creating contract documents. This capability will greatly reduce the designers’ efforts to either build an object or search/find/edit an object necessary for the development of their project. Considering that an advanced model may contain hundreds of objects this would represent a huge time savings and improve the modeling process.

Nowadays, satellite remote sensing technology has been applied in many fields of socio-economic development, including search and rescue at sea. Systems with the integration of remote sensing satellite technology have made the search and rescue operations faster, more accurate and more efficient. With the search and rescue systems at sea, remote sensing satellite motion simulation is an important task. This helps the authorities to identify and select the appropriate remote sensing satellite image data source to assist in processing and zoning search and rescue at sea. However, in Vietnam, it is difficult to determine the satellite image data source for the search and rescue situations. Therefore, the research team built a remote sensing satellite motion simulation program based on two-line element data. This is the data source that has been used in astronomy research. This program will simulate satellite orbits in real time and at any time. The accuracy evaluation result of satellite orbit simulation have been compared with online remote sensing satellite tracking systems in the world. The research result show that the satellite orbit simulation has ensured accuracy.
