ACCU-Track Civil ATC/MSSR Interrogator

accu-trackThe ACCU-Track Monopulse Secondary Surveillance Radar is a completely new interrogator designed to meet the most demanding air traffic control system requirements and replace aging SSR interrogators that can no longer be economically maintained.

The ACCU-Track-M MSSR is a long-range, monopulse interrogator with 2,000 watts of output power, ISLS operation, three receiver channels, RSLS, GTC/STC, target extractor, and target tracker. The ACCU-Track-S MSSR includes Mode S level 2 Enhanced Surveilance. The ACCU-Track outputs digital target reports (plots) in ASTERIX formats over Ethernet to the radar data processor or air traffic control station.

Significantly lowers maintenance costs

The ACCU-Track MSSR family employs modern COTS, programmable VME architecture to make this the smallest, full performance MSSR available today. The ACCU-Track meets the requirements of current FAA and international standards for identification and air traffic control systems including remote control and monitoring, and fault detection and isolation capability. The reliability, maintainability and supportability of the ACCU-Track significantly lowers maintenance costs.

ACCU-Track measures and reports transmitter power, pulse width and pulse spacing, receiver sensitivity and antenna VSWR. This allows the detection and repair of a degrading line replaceable unit or antenna system before it actually fails.

Fully redundant

Both ACCU-Track-M and ACCU-Track-S are available as a Dual Channel fully redundant system, that includes two MSSR interrogators, two uninterruptible power supplies, two network switches and a switchover unit, housed in a fourfoot rack. Each ACCU-Track is also available as a Single Channel interrogator. Each of these systems is available with any listed option.

accu-trackACCU-Track Offers State-of-the-Art Technology
The LDMOS linear transmitter allows precise, digital waveform control including output power, pulse width, rise and fall times - all under software control.

The digital software radio receivers track each other precisely, eliminating temperature compensation and calibration due to drift - all under software control.

Field programmable gate arrays perform all logic functions including reply processing, defruiting and degarbling, monopulse determination, transmitter and BITE modulator drivers, system timing, I/O support and switchover unit support - all under software control.

Four PowerPCTM processors perform target detection, code validation, target tracking, false target suppression, system manager and server functions.
