If you’re receiving data optically from a space based laser, yes you are quite vulnerable to your detector being jammed by a much closer laser that doesn’t have to be nearly as powerful to add noise to the signal. Why do you think GPS is so easy to spoof? Actually I just googled (clauded?) to learn more about space lasers and found a paper describing interrupting quantum key distribution (tamper evident but not jam proof!) with a 1kw laser on the ground pointed at the satellite! So it really does not take many photons to fuck up an encrypted signal. “ Vulnerability of Satellite Quantum Key Distribution to Disruption from Ground-Based Lasers” | ||
