See what your antenna hears
If you feed us aircraft, there has always been a way to check your box in the first hour: open tar1090 with your station id and the map shows only the aircraft your receiver delivered. Empty means something is wrong. Aircraft means it works. That link sits on your stations page and it has never gone anywhere.
Ships feeders had no equivalent, and it showed. The answers we could give were all one step removed from the thing you actually want to see. The check page tells you a stream is arriving. Your station page counts the days and the hulls. The coverage map draws squares over the water you light up. All true, none of them "here are the ships, right now, from you."
That view exists now. On your stations page, an AIS receiver has a link called What it hears, on the map, and it opens the public ship map filtered down to the hulls your antenna delivered. A banner across the top names the station and counts what is on screen, with one link back to everything.
It is the same map, showing less
This is worth being precise about, because it is the part that could quietly go wrong. The filtered view is not a second map assembled from a second query. It is the exact snapshot the public map already polls, with rows removed. Every rule that governs what a ship row contains is the same line of code it was before: private recreational craft still arrive anonymised with a surrogate id and no name, hulls that only a daytime sweep found are still hidden, positions are still rounded the same way. A filter can only ever show you fewer boats than the open map. It can never show you more of any one of them.
The unfiltered map has not changed either. It still marks a hull as heard by a Skydex receiver without saying which one. Which antenna heard which ship stays unpublished, because naming it would narrow a volunteer's position far past the coarse cell we promise. The filtered view opens only to somebody holding the station's own key, which is the same key that already lets you feed under that station's name.
Two smaller things
If your receiver never had coordinates set, the link still works. The map centres on the vessels themselves once the first batch arrives, rather than on an antenna position we do not have. Several live stations are in exactly that situation, and they were the ones the naive version would have dropped on empty ocean.
And a bug went with it. The tar1090 link was being handed to every station, ships receivers included. Clicking it filtered an aircraft feed by a station id that has never delivered an aircraft, so you got an empty map, which reads exactly like broken hardware. Ships stations now get the ships link, and if you paste an aircraft station id into the ships map, the banner says so in words instead of showing you a blank sea.
Two receivers on one roof? Register both, and each link answers for its own band.
