Satellites and GPS, sentence 9

GPS works because a phone listens for timing signals from several satellites and works out where it is from how long the signals took; GPS satellites carry very precise atomic clocks.

Who acts: GPS, phone, signals, GPS satellites · What happens: work, listen, work out, be, carry · To what, where: satellite, precise atomic clocks

This is a sentence of the lesson «Satellites and GPS» of the technology course of Mova's primary school. The page gives its syntax tree — a dependency tree in the style of Universal Dependencies — and its pragmatics clause by clause: who acts (GPS, phone, signals, GPS satellites), what happens, when and where, as Mova's frames read it from the tree.

The tree: Mova annot: Rust (en) → Haiku 5.5 (medium, Batches API) patches; gates UD 2.18; agreed by treeagree rules (Stanza, Trankit, spaCy trf): R1-cc-next ×1, R7-rel-agree ×2, R8-pos-agree ×2. The frames are read from the tree by Mova's frames reader (prag) when this page is built, the lesson read in order, so a pronoun may be resolved from an earlier sentence.
