This study compares in quantitative terms two methods of differential corrections to GPS positioning from the codebased pseudoranges. The differential method calculated from the coordinates (Latitude, Longitude and Altitude), called Position-Domain DGPS, ... see more

La evolución conjunta de las tecnologías de auscultación y las telecomunicaciones está permitiendo el desarrollo de Sistemas de Auscultación Automática de estructuras. En este trabajo se analiza la viabilidad de la aplicación de la técnica DGPS a la auscu... see more

Neste trabalho são mostrados os resultados de experimentos baseados em diferentes técnicas de transmissão de correções diferenciais a partir de uma estação GPS de referência, bem como resultados de um posicionamento que utiliza o conceito de DGPS em rede,... see more

As áreas de agricultura e pecuária geram impactos ambientais, principalmente em países de climas tropicais. Dentre os impactos estão os processos erosivos que podem ser mensurados em diferentes escalas de espaço e tempo, considerando sempre o contexto. O ... see more

O objetivo deste trabalho é demonstrar a possibilidade de compactação dosdados contidos na mensagem RTCM tipo 1, utilizada na transmissão de correçõesdiferenciais para o DGPS. Foram analisados quais dados poderiam ser suprimidosou modificados e, em função... see more

A differential global positioning system (DGPS) is one of the most widely used augmentation systems for a low-cost L1 (1575.42 MHz) single-frequency GPS receiver. The positioning accuracy of a low-cost GPS receiver decreases because of the spatial decorre... see more

The aim of this paper is the proposal of an innovative system for commercial transplanter to allow the automatic point-laying location of each vine cutting, without any kind of field preliminary squaring. A DGPS-RTK system is able to calculate the vine cu... see more

A Marine Digital Elevation Model (MDEM) of the still active volcanic area of Panarea caldera is presented in this paper. A fast and accurate survey was performed by means of the Differential Global Positioning System (DGPS) geodetic technique coupled with... see more
