		lxgr 5 days ago \| parent \| context \| favorite \| on: Time Station Emulator Satellite-based time signals also seem easier to spoof, given the inherent power constraints of the transmitters. That said, newer ones can use authentication, which (together with a reasonably accurate local oscillator) can prevent at least trivial spoofing.
