Rockwell Collins introduces WAAS GPS and ADS-B units

Looking ahead to technologies that likely will be commonplace in tomorrow’s business jet cockpits, Rockwell Collins has introduced a GPS receiver with WAAS (wide-area augmentation system) capability and a new traffic surveillance system that can host ADS-B (automatic dependent surveillance-broadcast) applications.

The GPS-4000S WAAS-enabled receiver will be approved for primary navigation on approach, allowing flight crews to take advantage of the growing number of LPV (localizer performance with vertical guidance) procedures being commissioned at U.S. airports. Having a WAAS receiver onboard also eliminates the FAA requirement to run a computer-based prediction of RAIM (receiver autonomous integrity monitoring) availability along the intended flight route for all RNav (area navigation) routes, SIDs (standard instrument departure) and STARs (standard terminal arrival route).

The first customer for the GPS receiver is the FAA, which is adding the WAAS LPV approach capability to its flight inspection aircraft. The unit will begin shipping to customers early next year, with an additional upgrade for the flight management systems in Collins Pro Line 4 and Pro Line 21 avionics enabled to fly the LPV procedures around that time.

Rockwell Collins has also introduced the TSS-4100 as its next-generation TCAS II (traffic alert and collision avoidance system) for business jets. The integrated system combines TCAS and mode-S transponder functions, as well as emerging ADS-B applications, into a box that the avionics maker said is the same size as current-generation TCAS units. The TSS-4100 uses a combined TCAS/mode-S antenna, further simplifying the design.

Codeveloped with Rockwell Collins’ air-transport division, which is designing the cockpit for the Boeing 787, the TSS-4100 will give pilots a full TCAS II with the added benefits of ADS-B’s enhanced traffic display. Intended as part of the FAA’s next-generation air transportation system (NGATS), ADS-B signals will provide a host of additional data to pilots, including aircraft registration, groundspeed and even intended course. The ADS-B integration will also aid pilots during self-sequencing maneuvers and on-ground operations.

The TSS-4100 will be available in 2008, according to Collins.
