GPS Global Positioning Systems - Principles and Implementation Approaches

This article references the internationally acclaimed textbook "GPS Global Positioning Systems - Inertial Navigation and Integration" (Wiley, 2001). This comprehensive work introduces both Global Positioning Systems (GPS) and Inertial Navigation Systems (INS). GPS technology determines terrestrial positions through satellite signal triangulation, typically implemented using trilateration algorithms that process time-synchronized signals from multiple satellites. Inertial Navigation Systems utilize inertial forces from accelerometers and gyroscopes to calculate position and orientation through dead reckoning algorithms, often involving Kalman filtering for sensor fusion. The book provides detailed explanations of both technologies' fundamental principles and practical applications, supported by extensive real-world examples and case studies. Key implementation aspects covered include coordinate transformation algorithms, error correction methods for GPS signal processing, and inertial sensor calibration techniques. These examples help readers thoroughly understand complex concepts through practical system integration scenarios, demonstrating how GPS and INS components can be computationally combined for enhanced navigation accuracy.
