“…The cost of monitoring includes the costs of RTK GPS receivers, power supply, communication, logistics, personnel, etc. Several authors have proposed the use of low-cost GPS L1-only monitoring receivers (Cina and Piras, 2014;Cina et al 2013;Yu, 2011;Verhagen et al 2010;Brown et al 2006). The short-coming of this approach is the potential degradation of the position solution due to the effects of ionospheric delay, and the challenges in the ambiguity resolution.…”

Resumo:Os principais objetivos deste trabalho são desenvolver um modelo cinemático análise de deformação para deslizamentos utilizando procedimentos de filtragem de Kalman; e utilizar as observações de TUSAGA-Aktif Rede GNSS na Turquia para determinar os campos de velocidade de uma área de estudo deslizamento de terra na região do Mar Negro oriental da Turquia. Trinta e cinco foram estabelecidos (35) pontos para a determinação de 3-D em tempo velocidades dependentes da área de estudo deslizamentos de terra. Deslocamentos e velocidades de ponto foram determinadas por ponto único modelo cinemático para realizar a análise estatística 3-D, e para avaliar a importância dos deslocamentos de ponto e velocidades usando três observações periódicas de TUSAGA-Aktif Rede. As determinadas velocidades foram usadas para gerar os campos de velocidade da área de deslizamento de terra por três épocas, utilizando Sistema de Informação Geográfica (GIS). Os resultados obtidos indicam que quase todos os pontos monitorados mostrou movimentos significativos, com diferentes magnitudes de velocidades. Foram também determinados os rumos do movimento dos 35 pontos monitorados. Os resultados mostram que as tendências dominantes dos movimentos de deslizamento de terra na área de estudo estão nas direções noroeste e nordeste. Estes resultados estão de acordo com os resultados anteriores obtidos na mesma área de estudo cerca de dez anos atrás

“…Several authors have proposed the use of low-cost GPS L1-only monitoring receivers. [12][13][14][15][16] The short-coming of this approach is the fact that, unlike the dual-frequency data, the single-frequency GNSS receivers' data cannot be corrected for ionospheric delay. 17 The single-frequency receivers also have inherent problem in the ambiguity resolution.…”

Application of Low-Cost GPS Tools and Techniques for Landslide Monitoring: A Review

et al. 2014

View full text Add to dashboard Cite

The main goal of our ongoing research is to design a low-cost continuous monitoring system for landslide investigation using the Reverse RTK (RRTK) technique. The main objectives of this paper are to review the existing Global Positioning System (GPS) tools and techniques used for landslide monitoring, and to propose a novel low-cost landslide monitoring technique using Reverse RTK GPS. A general overview of GPS application in landslide monitoring is presented, followed by a review of GPS deformation monitoring systems and some of the factors used for their categorization. Finally, the concept, principles and advantages of the proposed new landslide monitoring system are discussed.

This chapter describes the preliminary study of real-time data streaming in support of the proposed low-cost landslide monitoring system using the Reverse Real-Time Kinematic (RRTK) technique. The RRTK algorithm was implemented by streaming raw Global Positioning System (GPS) data of both the reference and roving station(s) to the control centre for processing, and transmission of the position solution to the roving station. The main purpose of the data streaming was to investigate the quality of the measurements, for utilization in landslide modelling and analysis in near real-time. A novel methodology using a high pass filtering technique was implemented, to detect outliers in the observations. Also, the autocorrelation of GPS time series was investigated.
