Abstract Numerous programmes have been conducted to search for techno-signatures using optical wavelengths. PANOSETI provides the opportunity for a link and follow up to new infrared laser optical ground stations (OGS) in the event of first contact for ETI communications within our local neighborhood of the Solar System. The OGS has a transceiver communications system that can provide the opportunity for post-contact protocols to be initiated with a potential ETI.
