Evaluación del rendimiento del sistema de posicionamiento global (GPS) e INS/GPS sobre una trayectoria establecida.

Abstract

The analysis of the accuracy of the Global Positioning System (GPS) versus hybrid positioning system GPS and Inertial of Navigation. System (INS) allows determining which them offers greater accuracy in following an established path a GPS Module, inertial sensors and the Pixhawk controller card uses Kalman filter as a coupling method between GPS and INS, a telemetry system for data transmission and a decoder for the remote control. The test scenarios consist of two paths executed at 12:00 and 20:00 due to the atmospheric conditions present at different times of the day. It is confirmed that the GPS / INS system had an accuracy greater than GPS up to 73.6% on average of the two scenarios during the which day, while at night it increases the precision of up to 17.5%, function meansthe that the implemented system has as a correction of errors produced due to ionization of the ionosphere, being the main attenuation factor of the GPS signal in the communication channel.
