Tecnologias GNSS aplicadas em campo, nos modos RTK rádio interno e RTK via NTRIP

The georeferencing of rural properties in Brazil has already been a reality, since 2001, with the purpose of eliminating land grabbing and also to locate lands and properties through the Border Coordinate Pairs System. In summary, the use of RTK system and NTRIP system technology uses the mobile phone network to receive corrections in real time, through the internet. The Topography studies the instruments, methods of field surveys, calculations and even maps necessary for the most detailed graphics representations possibilities. The purpose is to define important details, such as dimension and coordination data of the earth's surface, without considering the curvature of the earth caused by its sphericity. The use of RTK technology has proved to be beneficial in main topographic surveys, and it allows us to acquire data from field surveys in real time. This article aims to collect data from rural and urban areas, in order to show the viability of the electronic devices in certain situations and places.
