Russia’s jamming of GPS signals marks a shift in its non-conventional attacks against the Baltic states, Lithuanian Foreign Minister Gabrielius Landsbergis said on Friday.

“They [Russia] are moving from the cyber domain, disinformation domain, towards a more physical one which affects airplanes, daily lives of people in our region,” he said in a joint news conference with his new Latvian counterpart Baiba Braže in Vilnius.

Estonia, Latvia, and Lithuania warned last month that Russia’s jamming of GPS signal was increasing the threat of aviation incidents.

Estonia on Wednesday summoned Russia’s chargé d’affaires to protest the jamming of GPS signals which led to disruptions in Tartu Airport.

The Estonian Foreign Ministry said in a press release that it “has caused serious damage to air traffic in our region, the clearest example of which is the suspension of flights between Helsinki and Tartu”.

Braže told the news conference in Vilnius that “it’s not a new phenomenon but it leaves a certain sort of consequence that is worrying”.

Landsbergis called for sanctions on those responsible for these actions, adding that “it is also very important to send a message to Moscow that they are not operating in a grey zone”.

“If they expect us to be silent, if they expect us to be quiet about the things that are happening, they are definitely not going to get that. We see, we know, and we act against it,” Lithuania’s foreign minister said.

This week, several European countries summoned Russia’s diplomats over hybrid and cyber-attacks orchestrated by Moscow or groups linked to it.

That's interesting, but from reading it, I think that they're trying to solve a different problem. The issue that the Baltics and Finland are hitting is GPS jamming creating problems with positional data, which is used for navigation.

But it sounds like these guys are looking at trying to solve the problem of providing synchronized clocks countrywide (which is related in that having synchronized clocks is required for some positioning systems, but not quite the same thing; you can have synchronized clocks without knowing your position). They're just using GPS as a time source.

Interestingly, they also mention possibly using this "new Loran" thing too (though to solve their time problem, not to determine location).

NITRO is extensible to additional and future time sources and technologies (e.g., over- the-air radio & TV broadcasts, Signals of Opportunity, planned ELORAN solution)

EDIT: For their timekeeping problem, I'm also kind of surprised that there's no reference to the atomic clock radio transmissions that we run for the contiguous US. But maybe that's vulnerable to spoofing or something.

https://en.wikipedia.org/wiki/WWVB

WWVB is a time signal radio station near Fort Collins, Colorado and is operated by the National Institute of Standards and Technology (NIST).[1] Most radio-controlled clocks in North America[2] use WWVB's transmissions to set the correct time.

The normally 70 kW ERP signal transmitted from WWVB uses a 60 kHz carrier wave derived from a set of atomic clocks located at the transmitter site, yielding a frequency uncertainty of less than 1 part in 1012. A time code based on the IRIG "H" format and derived from the same set of atomic clocks is modulated onto the carrier wave using pulse-width modulation and amplitude-shift keying at one bit per second. A single complete frame of time code begins at the start of each minute, lasts one minute, and conveys the year, day of year, hour, minute, and other information as of the beginning of the minute.
