Data Handling in GNSS Receiver Network and Ionosphere Monitoring Service Solution

Abstract

This paper describes software and hardware solution that enables Global Navigation Satellite System (GNSS) data acquisition with ground based stations network. The solution relies on original data format and relational database management system. C++ library code and database schema SQL-structures are created automatically from Javads Receiver External Interface Specification (GREIS) with a C# application. This solution was used to create a real time ionosphere monitor service based on Feodorov Institute of Applied Geophysics ROSHYDROMET GNSS-receiver network.

BitTorrent is Apt for Geophysical Data Collection and Distribution

“…The size poses a problem for both remote stations'network access channels and distribution centers. From [Aleshin et al, 2014] we also learned that stable connection to the Internet is rather uncommon at remote locations causing data consistency and availability problems. As shown above, we did not feel comfortable with FTP or SMTP so we decided to find another solution to transfer that amount of data.…”
