SPx Radar Web Server FAQs

Use SPx Radar Web Server. SPx Radar Web Server receives ASTERIX CAT-240 radar video, converts it into scan-converted images and serves them to web browsers, which request images for a defined geographical area through a REST interface and display them with maps, tracks and other layers.

In a typical system, SPx Server at the radar site receives and pre-processes the radar video, and SPx Radar Web Server scan-converts it and serves the images to any number of connected browsers. Images are supplied as PNM or BMP images, which the web client can mix with its own layers. A built-in web client display is included.

Use SPx Radar Web Server. SPx Radar Web Server receives ASTERIX CAT-240 radar video, scan-converts it on a server and serves the images to a standard web browser, including browsers on iOS and Android phones and tablets, provided the device has a network connection to the server.

Each user can change scale and position independently, and tracks, AIS and ADS-B can be shown with the radar video. The server runs on Windows or Linux, on site or in the cloud.

SPx Radar Web Server runs on Windows or Linux servers. Clients need only a standard web browser, so radar video can be viewed on Windows, Linux, macOS, iOS and Android devices.

For supported browsers, see the platforms and compatibility FAQs. See also SPx Radar Web Server.

SPx Radar Web Server serves track reports to browsers in an extended GeoJSON format. This covers primary radar tracks, fused tracks, AIS and ADS-B, which the browser renders with the radar video and map.

SPx Radar Web Server is licensed by the maximum number of clients, with standard options for 2, 5, 10, 25 or 100 clients. More clients can be supported if the host has sufficient resources, or several servers can share the radar data and each serve fewer clients.

Each user gets an independent radar presentation and can change scale and position on their own display to see the radar video at full resolution.

Yes. In a cloud-based system, a lightweight radar server or an HPx-346 unit receives the radar video and distributes it to a cloud-based server running SPx Radar Web Server. Client browsers then make HTTP requests for the specific areas of radar data they need.

SPx Radar Web Server can also run on a remote server rather than in the cloud. Either way, scan conversion happens on the server, not on the user's device.

See SPx Radar Web Server and the HPx-346.

Yes. SPx Radar Web Server is fully controllable at runtime through a client-side JavaScript API, so display applications can be built on web mapping tools such as Google Maps and Bing Maps. A built-in web client display is also provided.

Each client can also choose its view with query strings in the request URL and control any other runtime parameter through the RESTful API, without relying on JavaScript. The server itself is configured at start-up from a configuration file.

Other features include selectable radar colours, history trails, radar overlay on ENC charts and maps, secure protocols, remote control of SPx Server, and moving platforms using NMEA-0183 navigation data. See SPx Radar Web Server.
