On p. 24, in the section about "Münso: Home of the Loop", it indicates that the "Defense Research Facility 14" (FOA) is located "at Sätra". I can find no Sätra on the island of Münso on the map.
On p. 26, in the section about "Adelsö: Remnants of the Past", it describes the "Sätra Youth Correctional Facility". There is a Sätra clearly indicated on Adelsö on the map.
Where is the FOA located?
