Some results of designing a system for online collection of data from terrestrial recorders of global satellite navigation systems are presented. The specific features of applying VPN technologies in geophysical data collection systems in real-time mode are discussed. Two of the most popular software VPN implementations are analyzed for comparison: SSTP , available for Microsoft Windows , and the free OpenVPN package. It is shown that both variants have commensurable performance. In unstable channels with low throughput, SSTP ensures a higher capacity, and OpenVPN is more stable and better resistant to discontinuous decreases in throughput.
