Miniature simulator and scenario generator
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 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. For 2022, JLT added driver support for a large number of additional GNSS front-end receivers when using the hardware-in-the-loop (transcoding) feature of the unit to, for instance, transcode from one GNSS system to another.
JLT offers an easy-to-use, highly configurable and cost-free SimCon Windows application program that is downloadable from the JLT website. SimCon 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.
The CLAW firmware has been updated to allow live-sky almanac and ephemerides to be automatically uploaded from various externally connected GNSS receivers. This makes simulations using real-time live-sky constellations (such as used in simulating spoofing attacks) an easy task. A free firmware update is available from JLT.
