| Resumo | Nowadays, the existence of real time GNSS network has become a reality in several countries. In Brazil, there is available the RBMC (Rede Brasileira de Monitoramento Contínuo - Continuous Monitoring Brazilian Network; http://www.ibge.gov.br/english/geociencias/geodesia/rbmc/rbmc.shtm?c=7. However, given the actual reference station spacing, high-precision network-based positioning cannot be applied. In order to reduce this limitation, users in São Paulo State have the option of using data from the SP/Network (GNSS Active Network of São Paulo State). The main objectives of this network are to increase the number of GNSS active stations in São Paulo State and support researches concerning network-based positioning and related fields. The data are available in real time through the Internet using the NTRIP (Networked Transport of RTCM via Internet Protocol) protocol. In this paper it will be presented aspects related to the development and results obtained with an in-house software that has been developed at FCT/UNESP (São Paulo State University). This software will be available on the internet to realize the network-based positioning to São Paulo State users and/or researchers. The user must just choose the position, date, hour, and interval and the VRS data will be generated and sent by e-mail to the user. Data from SP/Network (GPS Active Network of Western São Paulo State) will be used as input for the software, where the reference stations are about 200 km apart. Concerning the network-based positioning implemented in the software, the VRS (Virtual Reference Station) concept is applied. But an alternative approach to VRS concept was developed. In the method, the integer ambiguities between reference stations are not resolved, and the network corrections are derived from external atmospheric (tropospheric and ionospheric) models. Related to the troposphere, the ZTD (Zenithal Tropospheric Delay) is computed using a NWP (Numerical Weather Prediction) model. In relation to the ionosphere, delays are computed from a Brazilian regional model. The method was tested and accuracy on the level of centimeter to decimeter was achieved (depending on the observable applied), which is suitable for several applications in Brazil. The internet page details, method description, results and analyses will be presented in this paper. |
