The SXblue ToolBox Android application for SXblue GNSS receivers allows the user to view and analyse the position data provided by the SXblue receiver and metadata related to its location. The user is also able to send commands that enable or disable some features: systems in use, mask angle or differential age, constellation in use: GPS, GLONASS, GALILEO, BEIDOU, SBAS. The SXblue ToolBox is also an NTRIP client capable of connecting to a NTRIP server for RTK corrections, thus allowing the receiver to issue very accurate location information. The application is able to record, save and transfer the raw data from the GNSS receiver, allowing post-processing activities on computers for surveying and geomatics professionals.
