Display Applications

Download Datasheet (PDF)

SPx Viewer-3D is a software application for Windows or Linux that proves a 3D visualisation of radar track reports arriving in SPx or ASTERIX format, as well as AIS and ADS-B messages. The software provides 2D PPI and RHI views and also a 3D view of track reports. The user may manipulate the viewpoint to observe the tracks and history trails from any angle.

SPx Viewer-3D receives track reports over a network interface and displays the track symbol as an overlay to a map or rendered terrain. Track history is shown as a sequence of trail dots, a track vector shows the estimated direction and speed of travel of the track and optional display of additional track details, such as track name and height. A typical application of the viewer is to show radar tracks from 2D or 3D radars, along with AIS and ADS-B information.

Input Tracks

Track input formats and sources include SPx, ASTERIX, AIS and ADS-B. SPx Viewer-3D supports multiple sources of the same track type.

Each track source has a unique IP address and port and any permutation and combination of supported radar track sources can be displayed; for example SPx track reports from a primary radar video, SPx track reports from a secondary IFF radar video, and ADS-B messages.

Proprietary and legacy track input formats, such as NMEA, YLC and GeoJSON, may be supported via Cambridge Pixel's SPx Track Manager product.


On Windows, SPx Viewer-3D is a standard Windows application and on Linux, the application is a server with a browser-based user interface.
The application provides an intuitive display of the tracks and local terrain, allowing the user to change the viewpoint in real-time.
