99.99% Service Uptime
With redundant infrastructure hosted in Tier 4 data centers and supported by load balancing and failover protocols, 99.99% uptime is guaranteed. SWAS ensures reliable, uninterrupted service for any demanding applications.
Flexible Access
Users can access RTK corrections through both L-Band satellite and NTRIP internet access, providing flexible solutions for diverse operational needs. The dual broadcast mode ensures SWAS remains a cost-effective and scalable service.
Cost-Effective Solution
SWAS offers flexible billing options, allowing users to pay only for the services they use. Its proprietary protocol reduces bandwidth consumption, lowering operational costs while maintaining high performance.
Seamless Integration
SWAS is compatible with most GNSS receivers and supports RTCM 3.X data formats as well as NTRIP 1.0/2.0 protocols. Its SSR-to-OSR conversion for PPP-RTK, combined with available APIs and SDKs, enables seamless integration and scalability for both OEMs and end users.
Cloud-Based Ionospheric Modeling
SWAS uses real-time cloud-based ionospheric and tropospheric models to provide accurate corrections. By leveraging real-time observational data, SWAS ensures robust GNSS positioning, enhancing reliability in all environments.
Efficient Bandwidth Management
The Differential Data Compact Transmission Protocol (DCTP) reduces bandwidth usage by more than 40%, lowering data consumption costs without compromising performance, data integrity, or security.
