TopStar C is a certified GPS/SBAS receiver solution supporting both RNAV and RNP operations, including RNP approaches to LP and LPV minima. It delivers essential information, including guidance for both 2D and 3D approaches, all required parameters for ADS-B, and advanced indicators to detect jamming and spoofing. TopStar C is available in both linefit and mid-life upgrade for civil and military airplane, helicopter and UAV.

FORCES

Certified GNSS Accuracy

TopStar C delivers certified GNSS performance for all flight phases with LPV, RNP, and ADS-B functions. Backed by EASA/FAA certifications, it's designed for reliable navigation and available for both linefit and retrofit on aircraft and helicopters.
Easy to Integrate GPS

Operating as a standalone GPS or integrated with inertial systems, TopStar C is ARINC 743A-4 compliant. It reduces integration costs and supports military and civil operations under harsh environmental conditions.
Future-Proof GNSS Tech

With GPS and Galileo compatibility, TopStar C supports evolving needs in aviation, autonomous vehicles, public transport, and maritime. Its patented multipath mitigation and dual-constellation support enable safe navigation in all mobility sectors.

Easy to integrate in UAV and UAM platforms

Leveraging experience from the aerospace sector, GNSS-based navigation systems are essential components in emerging applications such as advanced air mobility vehicles, and UAS requiring the highest safety levels (SAIL 4 and above). Combining resilience, safety and accuracy within a low SWaP footprint, TopStar C – whether used as a standalone receiver or as a GNSS module – provides an ideal solution to meet the stringent requirements of these new platforms.

Why choose the Thales TopStar C: boasting a core system that draws on the experience gained from millions of commercial aircraft flight hours, the ETSO-certified TopStar C is extremely reliable and accurate, which helps to give both crew and passengers an unrivalled level of s afety. TopStar C is ruggedized to adapt to harsh environments.

FEATURES

ATM is evolving from a radar-controlled environment to trajectory-managed airspace. With the inception of high-precision approach features like Localizer Performance with Vertical guidance (LPV), Required Navigation Performance (RNP) and Automatic Dependent Surveillance-Broadcast (ADS-B), GPS receivers have become the cornerstone of navigation systems. Consistent accuracy, availability and reliability are essential in order to safely accomplish ever more demanding missions, using the WAAS and EGNOS satellite constellations.

Galileo

In the near future civil aviation will use a combination of GPS and Galileo, and TopStar C will be upgraded with multi constellation capability when offered for civil aviation.

Ground transportation

Using the experience gained in the aerospace sector, navigation systems using GPS or multi constellation (GPS + Galileo) will be integrated for emerging applications such as driverless cars as well as for public transportation (buses, trams and trains), professional UAVs, maritime and future generations of robotics. The next-generation TopStar dual-constellation GPS and Galileo-based solution from Thales is thus set to play a crucial role in the development and testing of safety/liability critical solutions for all forms of transportation, including rail.
