Sapfir

“Sapfir” is a satellite terminal developed by ZASLON JSC, operating in the Ku-band, an ideal choice as a high-performance stand-alone communication terminal, or a dependent backup solution for the VSAT system.

The main advantage of the SAPFIR satellite communication station, with the PhMBBS modem and its difference from VSAT mobile stations, is to ensure stable communication in motion and in the difficult interference environment – electric power lines, road poles and structures, tree crowns, precipitation, industrial and other active interference, the level of which can exceed the level of the transmitted signal by several orders of magnitude.

The modem implements the innovative technology for combining phase-manipulated broadband signals (PhMBBS/DSSS) with orthogonal code multiplexing (OСDM) channels, providing efficient processing of noise-like signals (NLS).
