Financial & Power Among Most Likely Spoofing Targets (

Financial & Power Among Most Likely Spoofing Targets (

Nation-states attacking financial institutions and power grids, and organized criminals stealing high value assets were deemed among the most likely spoofing scenarios in a recent presentation by Fugro.

Discussing “the world of spoofing,” as part of a presentation to the Dutch Institute for Navigation’s workshop on GNSS Interference and Authentication, the presentation discussed motivations behind spoofing. the different bad actors involved, and how likely such events were to occur.

Spoofing to protect high value assets was listed among the scenarios. Many believe that much of the spoofing seen in Moscow, the Black Sea and Baltic is part of a Russian drone defense system for VIPs and high value assets. Most drones are programmed at the factory with the location of airports and to fly away from airports. Spoofing the vicinity of a high value asset to make it appear to be an airport would prevent these drones from intruding.

Concern about the susceptibility of many receivers to spoofing and jamming has increased greatly over the last 12 months as a result of the events in Russia and elsewhere around the world. The RNT Foundation and ATIS are co-sponsoring a free workshop about smart/resilient timing receivers on the 17th of April in the Washington, DC area. Click here to find out more and register.

BlueSky GPS Firewall from Microsemi (video)

Take a quick look at a demonstration of our new BlueSky™ GPS Firewall. The BlueSky GPS Firewall solves the problem of protecting already deployed systems by providing a cost-effective overlay solution installed between existing GPS antennas and GPS systems. Similar to a network firewall, the BlueSky GPS Firewall protects systems inside the firewall from untrusted sky-based signals outside the firewall.


NOTICE: GPS Week Number Rollover in TimeSource 3×00 products

The GPS system has a week rollover event once every 1024 weeks (~19.69 years). The next scheduled GPS system week number rollover will happen on 7th April 2019. The TimeSource system rollover occurs 24 weeks ahead of the GPS system rollover. Starting on 21st October 2018 the TimeSource system date jumps back to year 1999 (7th March 1999). The system remains locked to GPS and there are no alarms to indicate this jump. No additional roll back event happens on the GPS system rollover date of April 7, 2019 since the TimeSource system rolled back 24 weeks early and continues to count forward through the April 7, 2019 GPS system rollover date.

This roll back has no impact to the PRS frequency outputs of the TimeSource system. The roll back affects the internal log timestamps associated with system event logs and Autonomous Output (AO) messages. This roll back also affects the TimeSource auxiliary time outputs for TOD (Time of Day) serial connection, and NTP (optional software license).
