Lydbrook, Gloucestershire, UK – 14 April,   Marc Weiss, time expert at the National Institute of Standards & Technology, the USA’s measurements standards laboratory and site of the NIST-F1 atomic clock, has taken delivery of a SENTINEL sensor for the detection of GPS jamming and interference for his lab in the Time & Frequency Division at Boulder, Colorado.

Marc, who was recently featured in the InsideGNSS publication (http://www.insidegnss.com/node/3851), is recognised as one of the World’s experts in GPS technologies including developing the first GPS receiver to support nanosecond-level time transfer in the early 1980s with Dave Allan, the creator of the Allan Variance.

The SENTINEL research platform, which was part funded by the Technology Strategy Board, researched the impact on GPS of low cost jamming devices and suitable alternative complementary technologies.

The SENTINEL report was recently released at the GNSS Vulnerabilities & Resilient PNT event held at NPL in the UK and a copy is available here.

The SENTINEL project deployed a number of sensors around the UK to determine the nature of the threat from GPS jamming and interference.  The sensor deployed at NIST represents the first non UK deployment of a SENTINEL sensor.

Marc Weiss commented, “With SENTINEL we can now determine whether changes in our GPS data are due to jamming and interference.  I am delighted that Charles and Chronos can support our mission to make the most accurate GPS measurements possible.  This fits right in with our long collaboration to encourage excellent synchronization in the telecommunications industry.“

Charles Curry, Managing Director of Chronos Technology said “Chronos is delighted to be working with Marc in expanding our research platform to new locations.”  He added “Marc and I have worked together on the steering groups of the International Timing & Sync Forum (ITSF) and Workshop in Synchronization in Telecommunication Systems (WSTS) for over 10 years and this deployment of SENTINEL represents a new dimension in our working relationship and we are looking forward to helping Marc in his research at NIST into GPS jamming and interference behaviour.”
