Best 'Performance-in-one-Box':

With 21 to 42 channels the NavX-NCS Essential is prepared for the next generation of R&D, system integration and production testing of high-volume GNSS applications. This means not only saving effort, time and lifetime-cost but also a superior price-performance ratio – factors, that are often crucial in today’s industrial purchase decisions. The NavX-NCS Essential is designed to meet the demands of your everyday GNSS work. No matter if it deals with research and development, system integration, testings in the chain of production or various other tasks. Flexible and adaptable: Today as good as in future.

More 'Capability-per-Box':

The capability to generate all GNSS signals of the upper L-band by combining the different modulations in one L-band frequency is unique on the commercial market for GNSS development and testing tools. The NavX-NCS provides you with GPS, Galileo, GLONASS, QZSS and SBAS (BeiDou / COMPASS signal simulation ready, optionally) in one chassis at the same time. Compare!

Unmatched 'Flexibility-by-Design':

The user selectable combination of 'performance' (signal channels) and 'capability' (modulation & frequency) is real high value you get from NavX-NCS. Its nearly unlimited combinations guarantee to perfectly suit both, your applications and your budget – whatever this may be.

'Plug-In Scalability' and 'Extendability-by-License':

Fully scalable from a basic GPS L1 simulator with 21 channels to a full multi-GNSS system with up to 42 channels. This means the simulation – and the ability to fully “manipulate” – all worldwide GPS / GNSS and regional SBAS systems supported in the upper L-band. With this flexible approach, channels and capabilities can easily be added to the base system whenever you may encounter additional testing needs. Just in time and one step after the other.


Typical application areas for the NavX-NCS Essential are the following:

  • Development of future or existing receiver products. Full software-based upgradeability of frequencies and navigation satellite systems make it capable to constantly keep ahead your own progress in development.

  • System integration of GPS / GNSS receivers in products like e.g. smartphones, PNDs or multi-sensor car navigation systems in automotive application.

  • Production testing within a broad range of different industries. From manual “single unit” up to fully automated remote control “high volume” testing of GNSS receiver products.

Numerous applications in numerous different industries along the complete value chain of GPS / GNSS receivers for mainly civil applications. They reach from product testing in receiver chip manufacturing over to system integration in chipset manufacturing and up to product development and quality control of OEM satellite navigation receiver devices. Automotive, consumer electronics including telecom and wireless. The NavX-NCS is also your first choice in signal simulation for LBS (Location Based Services) testing.
