1. LANDMARKS EVALUATION WITH USE OF QR-CODE FOR POSITIONING INDOOR ENVIRONMENT
Abstract: People tend to lose their sense of direction in closed environments and the role of indoor maps is to assist the user in navigating in these spaces, through understanding the environment, identifying reference points or positioning. Among the several forms of achieving positioning in indoor environments, this research used the method based on image

3. Experimental Magnetometer Calibration for Nanosatellites’ Navigation System
ABSTRACT This article deals with the problem of Earth’s magnetic field sensors calibration in the context of low-cost nanosatellites’ navigation systems. The attitude of space vehicles can be determined from the state estimation using information from three-axis inertial and non-inertial sensors. This study considers a three-axis solid-state magnetometer

4. Sistema de navegação inercial GPS/INS de baixo custo com compensação de erros por redes neurais artificiais / Low cost GPS/INS navigation systems with error compensation by artificial neural networks
Este trabalho aborda a aplicação de redes neurais artificiais (RNA) em um sistema de navegação inercial de baixo custo auxiliado por GPS. Busca-se suprir a necessidade que ocorre já que o GPS não trabalha em todos os ambientes, ou pode trabalhar de forma inadequada, durante certo intervalo de tempo. Desenvolve-se solução para prover a falta de inform

6. New technique for the implementation of digital demodulation of fiber optic gyroscopes / Implementação de uma nova tecnica para demodulação digital de sinal de giroscopio a fibra optica
Gyroscopes are devices used to measure angular orientation, being extensively employed for guidance, navigation and stabilization. Among the many types of gyroscopes, IFOG (Interferometer Fiber Optic Gyroscope), based on Sagnac effect, is the most interesting solution due to its high sensitivity, resolution, reliability, small size and EMI immunity. The pres
