Evaluar la capacidad de distribución de correcciones GNSS en tiempo real del Caster Nacional y Experimental basado en NTRIP.

Abstract

In this titling work, it was evaluated the ability to distribute GNSS corrections in real time from the main and Experimental Caster server of the RTCM Data Transport Network system via Internet (NTRIP) in Ecuador. It has two phases, in the first one, a means of interaction between Caster-user is created for the dissemination of data, for which a web portal was created for users to access the Caster, to obtain the data of positioning corrections in real time, a registration must be made, to be assigned a username and password for personal use. In the second phase an application was developed through which an assessment of the capacity of data distribution by the server is performed, that is, information is obtained from data consumption, bandwidths (BW), users, connections, stations, etc., an analysis is also carried out from the user's point of view, which must have access to the Internet through a mobile network to connect to the Caster, therefore there is an estimated value of mobile data use when measuring activities are performed through NTRIP. The processing of the information of the .log file of the Caster, until September 19th , 2019 has had 4712 connections, 2.2 Gbytes of data transferred in 1310 hours, 42 minutes and 54 seconds, an average BW of 500 bytes / sec. It is concluded that technical support is provided to the personnel of the Military Geographical Institute (IGM), as a particular case, the measurement activities of August 2nd, 2019 were analyzed, which were verified through the application with the information processing of the .log file of the Caster server. It is recommended to continue testing with the application, so that optimizations are executed to improve its operation.
