SPx Track Manager FAQs

Yes. SPx Track Manager treats each ASTERIX source as an independent input, even when several radars send to the same network address and port, provided each radar has its own SAC/SIC codes. Each input can be filtered, converted to another format and sent to one or more outputs.

• A single input can have multiple outputs, and format conversion is applied per output.
• Track filtering is enabled or disabled per output channel. The filter parameters are global to all channels.
• The runtime licence is based on the number of output channels required: 1, 2, 4, 6, 8, 10, 16 or 32.

SPx Track Manager supports standard formats including ASTERIX, GeoJSON, NMEA TTC, NMEA TTM, SAPIENT (BSI Flex 335), SEIWG ICD-100, SGF 1.1 and SPx, plus many proprietary radar formats such as Echodyne EchoShield, Robin Radar and Leonardo DRS RADA, and converts between them.

Published proprietary formats are: AN/TPS-70 ECGP, AN/TPS-75, APS FIELDctrl, BlighterNexus, DML (Denbridge Marine Ltd), Echodyne EchoGuard, Echodyne EchoShield (including third generation), JY-11, Leonardo DRS RADA, REL-4, REL-4M, Robin Radar, SkySafe GeoJSON and YLC-6. Many more are supported but cannot be listed because of NDAs.

A single input channel can be converted to several formats at the same time. See SPx Track Manager and supported radars.

Contact Cambridge Pixel. SPx Track Manager is designed to be extended to new track formats quickly. If you can share the format documentation (under NDA if necessary), Cambridge Pixel can provide a fixed-price quote quickly; there may be a small NRE charge.

Many proprietary formats are already supported but cannot be listed publicly because of NDAs, so ask even if your format is not on the published list.

Contact Cambridge Pixel or see the formats listed on the SPx Track Manager page.

Yes. In SPx Track Manager, set up two filter areas: an inner zone where the false tracks start, and an outer zone enclosing the area where they usually die out. Then set the filter to exclude tracks that are in the outer zone and started in the inner zone.

This suits clutter tracks that die out after a few revolutions of the radar, while other tracks pass through unfiltered:

• Tracks that started outside the inner zone are not filtered.
• Tracks that started in the inner zone but get beyond the outer zone are not filtered either.

SPx Track Manager can also filter tracks on position, speed and threat level. See SPx Track Manager.

Slant range correction converts the range a radar measures to an airborne target (the slant range) into ground range, so the track appears at its true position over the ground on a PPI display. SPx Track Manager can correct a track's latitude/longitude when it was based on slant range.

Without correction, an airborne track shown at its slant range appears further from the radar than it really is. If the radar is 3D and measures the target's elevation as well as its range, basic trigonometry gives the corrected ground range.

The effect is greatest for targets close to the radar at high elevation angles. At 45 degrees elevation, the slant range is multiplied by cos(45°), or 0.7071, to give ground range. At 5 degrees the factor is 0.9962, so slant range and ground range are within 0.5% of each other.

Yes. SPx Track Manager supports dual-redundant track streams: it enables one stream and switches automatically to the second if the first is lost.

Where dual radar trackers are used for high reliability, SPx Monitor shows which tracker is actively sending track data onto the network at any given time. See SPx Track Manager.

SPx Track Manager is application software for standard Intel PC or single-board computer (SBC) hardware. The suggested minimum is an Intel Core i5 or better CPU, 8 GB or more of RAM, and Windows 11 or a mainstream Linux distribution less than two years old.

Suitable Linux distributions include Red Hat, CentOS, Fedora and Ubuntu. SPx Track Manager is controlled through a web-based interface and has a remote API for system integrators.
