Lunar Positioning System satellites are broadcasting incorrect signals, not consistent but not random. Plotting footprints suggests some small areas where consistent displacements would occur, but mostly this would be registered as an error. We are asked to lend assistance.
The network operators of Lunar Navigation Services share data with us. It appears that network operations has been compromised. Sending correctly-signed updates causes a satellite to drop completely off net, though not damaged to external observation.
While we look at this en route, Luna City has requested EU military assistance. The Lunar Preservationist Party has claimed responsibility, and more formally denied it, so we assume this is an isolated faction.
LtCdr Jane speaks to the manufacturer to determine the minimum manufacture and shipping time for a new constellation. 20 can be done quickly, a full 24 will take a little longer. This is probably an unacceptable delay. However, navigation packages are available, and these could be mounted temporarily on existing spacecraft.

The initial shift manager Isaac Dormer has been replaced by Esa Villar; we also have contact with Toshio Kogo, head of the organisation, who appears to be an accountant placed by the three operating companies of which LNS is a joint venture.
Sophie Barnard, the last of the techies who actually worked on the system but retired six months ago, is en route from the south pole to the north.
Inspector Sam Barlow and Sergeant William Hobbes of the Luna City Police are following Barnard by hopper to the equator, to join her on the train there.
We have contact from JSSDF SDV Kaga, in Lunar orbit. They have traffic records which they’ll share with us.
