Abstract

SANTOS, Marcelo Soares Teles  and  AMARO, Venerando Eustáquio. Geodetic network for coastal monitoring of setentrional littoral of Rio Grande do Norte State. Bol. Ciênc. Geod. [online]. 2011, vol.17, n.4, pp. 571-585. ISSN 1982-2170.  http://dx.doi.org/10.1590/S1982-21702011000400005.

This paper presents the techniques procedures involved in implantation of the RGLS (Rede GPS do Litoral Setentrional do Rio Grande do Norte), with the objective of serving basic subsidies for geodetic surveys for monitoring of coastal areas, subject to intense geodynamic activity and socio-economic and ecological importance to the Rio Grande do Norte State. The methodology allowed the determination of geodetic coordinates and orthometric heights of stations with decimeters precision concerning the Brazilian Geodetic System (BGS), from positioning and leveling by GPS on relative method. In addition, it was possible the study of geodetic aspects involving GPS altimetry such as evaluation of the physical situation and the density of Benchmarks available, absolute and relative evaluation of the geoid model, the proposition of a methodology for precision GPS altimetry and development of a software for this purpose which contributed to geodetic knowledge in the studied area.
