Optimization of traffic simulation using GPS navigation records
(Instituto Tecnológico de Costa Rica, 2021)
A traffic simulation is a tool that permits constructing a virtual environment based
on a real one, with the objective to perform analysis about the actual conditions
and more important, apply changes to the virtual scene ...
Desenvolvimento e testes de software de um receptor de GPS para uso espacial
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Engenharia ElétricaAutomação e Sistemas; Engenharia de Computação; Telecomunicações, 2011-03-25)
Spacecraft move with high speeds and suffer abrupt changes in acceleration. So, an
onboard GPS receiver could calculate navigation solutions if the Doppler effect is taken into
consideration during the satellite signals ...

This paper presents the implementation of a GNSS receiver that
process the navigation data contained in the GPS signal. This prototype
is based using a FPGA Platformintegrating all modules included
in a GPS Receiver ...
REDUCCIÓN DEL MARGEN DE ERROR DE POSICIÓN EN SISTEMAS BASADOS EN GPS
(2011-12-08)
This paper is referred to the different positional errors associated with GPS systems, and it suggests an error correction model where the most significant multipath effects can be mitigated; the navigation message information ...
Analysis of precise point positioning with GPS and glonass data in different latitudesAnálise do posicionamento por ponto preciso com dados GPS e glonass em diferentes latitudes
(2020-01-01)
GNSS (Global Navigation Satellite System) is, nowadays, composed of two complete systems, GPS (Global Positioning System) and GLONASS (GLObal NAvigation Satellite System). Although the simultaneous development, the systems ...
Assessment of gps/glonass point positioning in Brazilian regions with distinct ionospheric behavior
(2020-01-01)
Nowadays GPS (Global Positioning System) and GLONASS (GLObal NAvigation Satellite System) are the main systems of GNSS (Global Navigation Satellite Systems), also composed by Galileo and BeiDou. After a long period of ...
Implicações do uso de recptores GPS de navegação sem conhecimento de suas limitações e configurações básicas
(Universidade Estadual Paulista (Unesp), 2008-04-07)
O Sistema de Posicionamento Global (GPS – Global Positioning System) permite o conhecimento da posição, via satélite, de localidades específicas como um ponto topográfico, um carro em movimento ou de uma pessoa caminhando. ...
