Problem of the use of dual-frequency GNSS Receivers in Beni

Abstract

Despite several approaches, Benin has always had difficulties in securing land. Among the causes of this insecurity are technical reasons, which are either related to the working methods or to the tools used. To overcome these difficulties, a good number of surveyors nowadays are increasingly equipped with the latest generation tools that are dual-frequency GPS / GNSS receivers for an efficient execution of works.
