The CAST-5000 produces a coherent wavefront of GPS RF signals to provide repeatable testing in the laboratory environment or anechoic chamber. The basic system generates four independent, coherent simulations that reference a single point and is configurable to support up to eight elements for CRPA testing. With an intercard carrier-phase error of less than 1 millimeter, the CAST-5000 is extremely accurate.

The system generates a wavefront of GPS when its GPS RF generator cards are operated in a ganged configuration. Each generator card provides a set of GPS satellites coherent with the overall configuration. Several RF generator cards may be utilized together, ensuring phase coherence among the bank of signal generator cards. The CRPA antenna, antenna electronics and the GPS receiver can be tested as a unit with or without radiating signals.

The CAST-8000 is a new simulator that merges the CAST-5000 CRPA tester with a CAST-3000 EGI tester. The CAST-5000/8000 has the ability to be “ganged” together with additional CAST simulators to provide multiple vehicle and/or multiple antenna test configurations.

The 18-channel miniature full-constellation CLAW GPS Simulator is a fully self-contained, low size, weight, power and cost (SWaP-C) miniature GPS simulator. It is very popular in manufacturing environments as well as R&D applications that require consistent and repeatable local GNSS signals at low price points.  The CLAW simulator does not require external computers for processing and control — it works fully self-contained by simply applying power, and storing location/time/date data in internal non-volatile (NV) memory, or by storing complex vector data to simulate highly dynamic scenarios. The CLAW also can be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals. JLT offers an easy to use, highly configurable and cost-free SimCon Windows application program that is downloadable from the JLT website.

The SimCon application allows random scenario generation and is thus usable to simulate leap-second events, week 1023 rollover events, or any other GPS live-sky scenarios including highly complex yet easy-to-create dynamic vector simulations. For authorized U.S. government users, a version that does not have altitude and velocity limitations is popular for low-Earth-orbit (LEO) simulations. Multipath simulation allows use of the entire 18-channel simulator capability. The unit can be field-upgraded with an easy to use in-field software upgrade feature. The CLAW is also very useful in GNSS receiver sensitivity testing for R&D or mass-production assembly lines as it allows accurate control of RF output power ranging from –100 dBm to less than –130 dBm with 0.1-dB resolution and typically better than 1-dB accuracy over the controllable power range.

The CLAW GPS Simulator also has a built-in RF signal generator with sweep, CW and random noise functions that are useful in simulating GNSS jamming scenarios, as well as GPS spoofing scenarios. The simulator comes in an FCC-certified metal desktop enclosure with numerous accessories.

Precision-sensitive applications such as autonomous driving, control of unmanned aerial vehicles (UAV), or positioning of aircraft during landing procedures in coordination with ground-based augmentation systems (GBAS) require that modern GNSS receivers undergo detailed tests before implementation.

Rohde & Schwarz signal generators like the R&S SMW200A and the R&S SMBV100B offer a unique approach to generating complex and highly realistic scenarios for testing of GNSS receivers that are able to work with diverse navigational systems such as GPS, GLONASS, Galileo, BeiDou and QZSS/SBAS signals. Both simulators can emulate them all for testing.

R&S SMW200A. The R&S SMW200A GNSS simulator (pictured above) can be used to produce complex interference scenarios with multiple interferers — all generated within the instrument itself. It can emulate up to 144 GNSS channels and can be equipped with up to four RF outputs. With its ability to simulate multi-constellation, multi-frequency, multi-antenna and multi-vehicle scenarios, the R&S SMW200A is able to cover a variety of high-end GNSS applications.

R&S SMBV100B. The R&S SMBV100B supports the same navigational systems, with access to 60 GNSS channels and one RF output, with the same ability to configure realistic scenarios including obscuration, multipath and atmospheric effects, as well as the specific characteristics of the antenna and the simulated vehicle. An integrated noise and CW interference generator also can be added.

Since the devices do not require an external PC for scenario configuration, all the tests can be created quickly through the user-friendly GUI. Due to all-encompassing instrument options available, both simulators can be set up to fit unique user requirements.

For testing GNSS receivers under controlled and repeatable conditions, the R&S SMW200A and the R&S SMBV100B provide extensive and cost-effective solutions. The platforms are ready to adapt to future requirements and testing of newly implemented GNSS signals.
