Temporary traffic orders would be in place in north Unst to handle visitors trying to see a launch, and residents have been invited to apply for vehicle passes.
Scott Hammond, chief executive of SaxaVord Spaceport, said: “A five-week launch window does not mean restrictions will be in place for five weeks.
“Restrictions will only be introduced if a launch attempt is scheduled, and we’ll provide at least 24 hours’ notice.”
Hammond said the company aimed to balance operational and safety requirements alongside a commitment to “being a good neighbour”.
He added that disruption would be kept to a minimum.
Local residents will have the opportunity to gain access to viewing spaces for test flights and launches.
