This article provides a comparative analysis of global navigation satellite systems (GNSS) augmentations current status and future user positioning accuracy requirements. The architecture of perspective GNSS wide-area precise augmentation complex sufficient for future user requirements is proposed. Experimental studies of these complex algorithms based on the use of existing system for differential correction and monitoring facilities are presented. On basis of making research the forecast of GNSS precise positioning systems development is done.
