RTK station — not the app or robot body. See our app vs. firmware vs. RTK guide if you're not sure which one you're dealing with.
The codes
1300 ("Schlechter Positionierungsstatus" / poor positioning status) is documented in Mammotion's manual. 1303 ("Roboter setzt das integrierte RTK-Modul zurück und versucht die normale Positionierung wiederherzustellen" / the robot resets its integrated RTK module and attempts to restore normal positioning) is not documented anywhere in Mammotion's manuals; two of the three owners below saw 1300 and 1303 together1.
Confirmed cases
Parked under a solid-roofed structure — signal blocked, per Mammotion's own moderator
A LUBA 2 parked roughly a meter under a covered terrace to keep it dry hit this error. A Mammotion moderator active in the thread diagnosed this directly: a solid terrace roof blocks satellite signal entirely, and the mower will "protest" with exactly this error. The moderator's own mower sits under a plastic-roofed or wood-with-roofing-felt garage instead, which lets signal through1. If your mower is sheltered under something opaque (concrete, dense tile, metal), that's the first thing to change.
Resolved after a firmware update, despite similar sheltered parking
A LUBA 2 AWD 1000 parked partly under a thin wood overhang initially hit the same 1300 error, its owner suspecting the same shelter-blocking cause. After updating to firmware 1.11.511.381, the error stopped appearing entirely, despite the mower's parking location not changing1. This doesn't rule out a partial signal-visibility factor (a thin wood roof blocks less than solid terrace concrete), but the timing is specific enough to note: if you're on an older build than 1.11.511.381, updating is worth trying before assuming your shelter is the problem.
Unresolved: daily recurrence with no shelter at all
The identical 1300 (and 1303) codes appeared every day at the start of mowing on a third mower parked fully in the open: 5 meters from the RTK antenna, original LUBA roof, antenna fixed in place. No shelter-blocking explanation applies here, and the thread doesn't record a resolution for this case1.
