A Search Space Optimization Technique for Improving Ambiguity Resolution and Computational Efficiency
An Optimal Method for Estimating GPS Ambiguities (OMEGA) that enables very high performance and computational efficiency has been developed and demonstrated. This method employs two search space reduction processes – a scaling and a screening process – that are related to the search space transformation and the ambiguity candidate filtering in multi-search levels. To obtain the highest efficien...
متن کاملAn Optimized Least-Squares Technique for Improving Ambiguity Resolution and Computational Efficiency
Donghyun Kim is a post-doctoral fellow in the Department of Geodesy and Geomatics Engineering at the University of New Brunswick (UNB), where he has been developing a new on-the-fly (OTF) ambiguity resolution technique for long baselines. He received a B.Sc., M.S. and Ph.D. from Seoul National University. He has been involved in GPS research since 1991 and is a member of the IAG Special Study G...
متن کاملIMPROVING COMPUTATIONAL EFFICIENCY OF PARTICLE SWARM OPTIMIZATION FOR OPTIMAL STRUCTURAL DESIGN
This paper attempts to improve the computational efficiency of the well known particle swarm optimization (PSO) algorithm for tackling discrete sizing optimization problems of steel frame structures. It is generally known that, in structural design optimization applications, PSO entails enormously time-consuming structural analyses to locate an optimum solution. Hence, in the present study it i...
متن کاملThe Volume of the GPS Ambiguity Search Space and its Relevance for Integer Ambiguity Resolution
In the theory of integer least-squares ambiguity estimation and validation, a central role is played by the ambiguity search space. In this contribution, the significance of the volume of the ambiguity search space is discussed and analyzed. It is shown how the volume can be used as an estimate for the number of grid points inside the GPS ambiguity search space. This is done for various measure...
متن کاملHybrid Teaching-Learning-Based Optimization and Harmony Search for Optimum Design of Space Trusses
The Teaching-Learning-Based Optimization (TLBO) algorithm is a new meta-heuristic algorithm which recently received more attention in various fields of science. The TLBO algorithm divided into two phases: Teacher phase and student phase; In the first phase a teacher tries to teach the student to improve the class level, then in the second phase, students increase their level by interacting amon...
