PNT: position and time you can cross-check.

Since 4 November 2026 our library checks the positions and times a net's members report against each other and against each member's own clock, and names the members whose reports cannot be true and why; it corrects nothing and chooses no position. A maker's software reads the findings through our development kit. Measured on simulated fixes.

Since 6 November 2026 the library also holds a net's positions to what is known of its ground: two members whose radios hear each other directly cannot be further apart than the radio reaches, and a member heard by a station whose place was surveyed cannot be further from that place than the link reaches. So positions moved together, which no comparison between members could show, are named against a fixed point. Where the radio measures the distance between two of them, a position that does not fit that distance is named too, nearer as well as further. The radio's range and distances are the maker's figures. Measured on simulated fixes.
