sunhillo stands at the forefront of global surveillance data distribution and conversion systems for both manned and unmanned aircraft (UAS, UAV).
With over three decades of experience, Sunhillo has successfully implemented radar data distribution systems for the FAA, Department of Defence, and Air Navigation Service Providers worldwide. The SureLine Software Suite (SureLine®) enables the integration of various surveillance data types (including radar, ADS-B, and UAS location) to create a unified situational awareness that can be displayed on our Surveillance Monitoring System (SMS) or incorporated into a UTM or Operations Center.
Our Solutions Include:
- Integrated tracking for crewed and uncrewed aircraft
- Ground-based ADS-B receivers
- Surveillance monitoring and visualization
- Radar protocol conversions
- Aggregation and fusion of surveillance data for UTMs
- UAV tracking and integration
- Beyond Visual Line of Sight (BVLOS) solutions
- Data diode for secure details transfer
- Bridge between UTM and ATC systems
Integration & Fusion of Surveillance Data
Empowering UTM systems for secure drone operations
Sunhillo’s Multi-track Fuser feature enables UTM systems to effectively manage multiple data streams from diverse sources such as radars and ADS-B, merging them into a single track. This innovation guarantees accurate tracking of each unmanned aircraft in the airspace, significantly enhancing UAV surveillance data collection and reducing display clutter caused by overlapping tracks.
The Multi-Track Fuser can connect to up to 32 sensors at once, with each sensor capable of processing up to 800 tracks continuously. In total, it can output as many as 5000 fused tracks, efficiently accommodating high volumes of unmanned aircraft traffic. This flexible system can handle input data and produce output tracks in various formats, including ASTERIX, CD2, and ASR9, with output data available in multiple frames such as SGF and ECGP.

UAS-Connector – UAV Tracking & Monitoring
Secure integration for BVLOS UAV operations
The UAS-connector (UAS-C) serves as a tracking and monitoring system for BVLOS UAS operating within controlled airspace.
Engineered for seamless integration with existing air traffic control (ATC) systems, it connects to the UAV ground control station (GCS) to relay positional data to a centralized UAS-C Gateway. Supporting multiple UAS-C connections, the UAS-C Gateway establishes a secure link to the connected UAS-C endpoints and acts as a gatekeeper for communications with ATC systems or other command centers.
With Sunhillo’s extensive experience in ATC communication products, the UAS-C Gateway can provide ATC systems with UAV surveillance in standardized, compatible data formats.
Requiring no additional equipment on the UAV, the UAS-C is suitable for all platforms, regardless of size or altitude. it offers critical situational awareness for pilots, with a sense-and-avoid display that tracks all aircraft in the vicinity and communicates with ATCs or local command centers.
the UAS-C connects to the UAS-C Gateway either remotely via an internal LTE modem or directly through Ethernet. The UAS-C PIC interfaces include a tablet display and USB headset for optional voice communication.
