Nature-Inspired Biogeography-Based Optimization for Estimation of GPS Receiver Position in Low Latitude Regions of the Indian Subcontinent

Abstract

The concept of biological species distribution in a geographical area laid a path to develop biogeography-based optimization (BBO) in order to solve real-time optimization problems. BBO is implemented on GPS receiver data that belongs to low latitude region of the Indian subcontinent in order to estimate the receiver position. 3D positional coordinates of the receiver obtained by using BBO algorithm are compared with the surveyed location coordinates to analyze the performance of BBO algorithm. From the estimated mean position errors, BBO is observed to be a better evolutionary computing algorithm in the estimation of any GPS receiver position which is located in low latitude regions of the Indian subcontinent. This algorithm can also be used for QZSS and IRNSS satellite systems.
