...NavX®-NCS multi-GNSS RF constellation simulator product line. Featuring new multi-RF output, optimized software, remote control, and NavMsg logging and input functionalities, NavX-NCS is the most flexible and capable RF signal generator for GPS, Galileo, GLONASS, and SBAS constellations worldwide. With up to nine L-band frequencies and 108 channels, the NavX®-NCS GNSS simulator redefines the current state-of-the-art in RF signal simulation by offering modular hardware that delivers more than twice the number of channels when compared with competitor products.
During a live demonstration at ION GNSS 2012, attendees will be able to view the new multi-RF output functionality of NavX-NCS Professional. While most standard GNSS signal generators can only simulate one or two simultaneous user antennas, NavX-NCS Professional provides users with the ultimate flexibility by enabling them to simulate two, three, or four separate multi-GNSS user antennas (signal sources) simultaneously from a single unit. Users can start with any number of RF outputs, and upgrade at a later stage as required.
The latest NavX-NCS control center software release V1.8.0 features several usability and control enhancements, including simulation and analysis of feared events such as phase/frequency ramps, jumps, and drifts to the NavX-NCS platform, which enables satellite operators and receiver manufacturers to test the integrity of multiple satellite signals more reliably. This function also allows the configuration and simulation of scheduled pseudo range errors, which may be caused by an abnormal satellite clock behavior.
By using a new and innovative navigation message capability, users can log and import essential message content. After message content has been extracted, specified errors can be added by manipulating the logged message content to emulate various errors, such as bit errors. Additionally, NavX-NCS can log user position data, thus enabling operators to store the simulated user trajectory—including attitude information —within a log file. NavX-NCS can now be remotely controlled without using a GUI. As a result, GNSS simulators can be integrated with existing automatic test systems, providing users with the flexibility to build commands into the existing test system.
