Extra Info

SPx Alarm Server runs as a backend server application on a Windows or Linux PC.

Multi-channel Input

SPx Alarm server can monitor up to four channels of primary radar tracks in SPx or ASTERIX CAT-48 format. It also supports three further track stream inputs for Fused Tracks (in SPx or ASTERIX CAT-48 format), AIS Tracks (in UDP Raw AIS or UDP SPx AIS format) and ADS-B Tracks. Support for various ADS-B formats/receiver manufacturers is built-in.

Georeferenced Zones

SPx Alarm Server supports georeferenced areas (or “zones”), gates and points which are defined either by editing a plain text configuration file, or by selecting points against background mapping in its graphical user interface (GUI). Associated alarm logic and conditions can then be configured to suit different scenarios and use cases.

Track Monitoring & Alerting

Once setup is complete, SPx Alarm Server can be deployed to continuously monitor streams of tracks and generate alarm messages based on preconfigured alarm conditions, such as:

Located inside (or outside) a specified area/zone
Entered and not left specified area
Proximity/CPA to a point or shape/area
Proximity/CPA to any other track (or to a specified track)
Entry/exit from zone
Area/zone occupancy time
Track speed, course, rate of turn, course deviation and type

When an alarm condition is triggered, SPx Alarm Server supports the sending of network alarm messages in NMEA-0183 Tracked Target Message (TTM) format (V1 or V2). A supplied utility allows these messages to drive the relay outputs of a Modbus/TCP device to support alarm sounders.

Web-based GUI

SPx Alarm Server uses a web-based configuration GUI that can be viewed and operated in standard browser software. The GUI includes a viewing window that includes background mapping (normal, light or dark) or background satellite imagery. The GUI displays tracks, areas, gates and points as overlays to the selected background mapping or imagery.

Network-based API

SPx Alarm Server is supported by an API, available in Cambridge Pixel’s C++ and .NET libraries, that provides full access to alarm configuration and triggered alarm state. This can be used by a client application to fully integrate alarm capability.
