The Next Generation of Timing & Frequency

CLAW GPS Simulator

18-channel GPS Full-Constellation Simulator

Test your equipment for the GPS Week Number Rollover Issue (WNRO)! The CLAW is ideally suited for testing the April 6th WNRO issue in GPS user-equipment. The test is trivially easy to set up using the free SimCon application.

The CLAW 18-Channel Full-Constellation GPS Simulator is the industry's first fully-self contained, low size-, weight-, and power (SWaP) miniature GPS Simulator module. In comparison to competitive products that require external computers for processing and control, the CLAW Simulator works fully self-contained by storing location/time/date data in internal NV memory, or by storing complex vector data to simulate highly dynamic scenarios. The CLAW can also be used to transcode NMEA or SCPI position/velocity/time (PVT) data into GPS RF signals, therefore allowing retrofitting of legacy GPS equipment with the latest generation GNSS receivers such as Glonass, Galileo, BeiDou, SAASM, M-code, or even with INS capability. New for 2018 JLT has introduced the easy to use, yet highly configurable SimCon Windows application that is freely downloadable using the link below.

The CLAW GPS Simulator using the freeware SimCon application allows random scenario generation and is thus usable to simulate leapsecond events, week 1023 rollover events, or any other GPS Live-Sky scenarios. Multipath simulation allows use of the entire 18 channel simulator capability with an easy 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 very accurate control of RF output power ranging from -100dBm to less than -130dBm with 0.1dB resolution and typically better than 1.5dB 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 is useful in simulating GNSS jamming scenarios, as well as GPS spoofing scenarios.

The CLAW GPS Simulator comes in an FCC-certified metal desktop enclosure with accessories.
