It's possibly me confused
But if you arrive in a system (eg: Sol), you can use the FSS to find the exact locations for USS can you not? I'm not sure if you need to honk or not?
If we assume you do not need to honk, then we now have a big separation in purpose between the Discovery Scanner and the FSS. ie: If every ship was given an FSS as standard it might be rather useful/productive to general gameplay experience, without the penalty of having to use cargo space for a Discover Scanner (which clearly is for more dedicated exploration purposes)?
There is no separation of purpose between the DS and FSS; they are part of the same thing. In the new system, think of the "honk" as a sonar pulse which returns echoes of things of interest in the system (but no details), and the FSS as a telescope used to determine the details about them.
**Current system:**
1. (Core Module) Scanner - populates your 3d center console scanner, detects USSs in flight, performs basic scans on targeted ships, etc
2. Basic / Intermediate / Advanced Discovery Scanner - this currently is the "honk"; populates the System Map and gives information on mission targets. Alternatively go to the NavBeacon for the same (and more) information.
3. Detailed Surface Scanner - this is the scanner which gives detailed information on a planet; material composition etc. Fleshes out data available in the System Map and yields "First Discovered by" tags.
**New System:**
1. Same as before.
2. Discovery Scanner - replaces the current B/I/A DS, still the "honk", gives full information on the primary star and populates the FSS (below) with "gravity anomalies" in *unexplored systems*. Systems previously explored by Commanders will show up as if you'd done an old-style "honk". Yields monetary bonues equivalent to the old "honk" (and first-discovered-by on the primary star?)
3. Full System Scanner - new interface mode of the DS, *part of the same module as the DS* (ie, 2 & 3 are built into the same hardware); allows you to fully scan a system after the "honk". This gives the same information as the 2 & 3 of the old system. On top of that, it allows you to scan for the new "persistent" USS's in the system (and possibly other stuff such as generation ships etc). Yields "First Discovered by" tags.
4. Detailed Surface Scanner - is completely new gameplay and information now (it's original functionality is now part of 2&3); used to fire probes at planets to map a planet. Mapping a planet reveals persistent POIs on the surface such as volcanoes or brain trees. Yields the new "First Mapped by" tags.

Unsure whether you will always need to "honK", it was described as being the first step in entering the FSS interface during the exploration live stream, which indicates that yes you do. But in the BGS live stream they seemed to show just using the FSS interface directly.
Regardless, the "honk" and the FSS are part of the same module, and are now used for many different purposes, not just exploration. You still don't *need* it as you can get most of the same information from the Nav Beacon. The DSS remains mainly an exploration tool, although miners might be interested in it too now as it can be used to detect resource-rich areas in rings. We'll find out more about that next week.
