Applied updated element sets for US Molniya sats.
Two most likely candidates, USA 259 (Trumpet-6) and USA 198 (SDS-3), can still be excluded by TDOA and TDOA drift analysis.
Considering the uncertainty when back propagation to 2026-02-11, e.g. USA 259 along track offset > 3σ

Revisiting time difference, as well as time difference drift, of two station data of 2026-02-11 GPS jamming event, Kosmos 2546 matched perfectly.
While other US classified sats are a bit off, such as Trumpet 1/2/6.

Mickey is a reliable analyst/source. If you don't follow him.
He's been provided with the latest most accurate known TLEs for the NRO classified HEO objects and we shall see what he comes up with as the McCant's element sets are very dated.

One of the complaints about the Outer Space Treaty is that many of its provisions are vague and subject to wide-ranging interpretations, a decision that was intentional. thespacereview.com/article/5…

I don't disagree with anything in this but it is crazy how this is NOT the message that is coming out of the WH, which is apparently determined to steamroll over all the US' existing cooperative agreements

Something is interfering with GPS, but “we found you” is not earned yet. EKS is plausible, but active classified NRO HEO/SDS objects occupy similar geometry and appear omitted. The NRO is not above spectrum abuse. Without direct RF custody, this remains theory, not attribution.

Rocket Lab is being added to the Nasdaq-100 Index.
This is a landmark moment for the team. We're incredibly proud of what we’ve achieved, and even more excited about what is still to come.

High-resolution @planet satellite imagery from this morning shows the pontoon bridge leading to Chonhar from Crimea. Dozens of trucks are waiting their turn to cross toward Kherson Oblast, not a single truck or car can be seen traveling in the opposite direction, toward Crimea.
