SPx Track Manager provides a solution to integrate and filter sensor data from many different manufacturer’s radar and tracking systems.

Advances in radar technology have created environments where cutting-edge equipment is being used alongside legacy models. For surveillance and detection, merging data from a wide range of radars and sensors from different manufacturers has presented a difficult new challenge for developers.

SPx Track Manager was developed by Cambridge Pixel as the solution; a multi-function, multi-channel utility to support processing track data from a range of radars and sensors. The essential features include track format conversion, filtering, correction, network routing and dual-redundant operation.

The track manager converts incoming tracks in different standard and proprietary protocols to a standard internal representation. Each track can then be filtered based on the track’s location (geographical area), speed, course, altitude and classification. Multiple filters can be applied using the track manager’s multi-channel capability, allowing tracks to be selectively sent to different network destinations. Tracks may also be corrected for fixed errors in range and/or azimuth for a given radar source.

This solution was successfully deployed as part of a national air defence system. SPx Track Manager was used to convert track streams from multiple legacy radars across the country into a standard format, applying azimuthal correction to track reports where necessary. The converted track reports from the track manager were merged using SPx Fusion Server and then displayed to operators as a national integrated air picture in the ASD-100 software.

SPx Track Manager has a web-based interface that includes a map display of track positions as well as configuration options for filters, geographical areas and other operational features. Operator-initiated classification and manual filtering of specific tracks via display applications is supported through a network control interface.

Supported track inputs include Cat 48, NMEA TTM, GeoJSON, SGF 1.1 and a number of proprietary formats. Converted, filtered and corrected tracks can then be output in a number of formats including Cat 48, SPx and NMEA TTM.

Commenting on the new product, Cambridge Pixel's managing director, David Johnson, said "SPx Track Manager is an extremely versatile product that handles many interfacing, translation, conversion and filtering tasks that are commonly encountered when building radar systems.”
