The process still starts with the “honk” (system scan), though its usage is now the start of a more engaging process (if all you did before was scan for some credits, don't worry, the scan still awards credits.)
The system scan now returns an aggregated display of how energetic the electromagnetic emissions are in the system. Signals are sorted on a low to high scale by their apparent energy. For example, emissions from rocky clusters will appear at the lower end of the scale, hot gas giants at the upper range. This information requires some interpretation as signals can overlap.
You are able to tune the focus of your sensors to a particular point on the scale, making emissions from objects at this range much clearer, at the cost of filtering out signals returned from bodies not emitting at this range.
As you move the view around, you are aiming your discovery scanner sensors. To aid you, the discovery scanner view also features a repeating sweep of gravitational disturbance detected in the system. You can use this sweep to narrow your search for stellar bodies, as well as start your search around the star's orbital plane, which is revealed by the initial system scan.
Emissions that come close enough to your view’s focus are represented by signature patterns around a central reticule. If you are tuned to the correct point on the energy scale the signal will show as a symmetrical pattern clearly showing the direction towards the origin of the signal, allowing you to locate it. The further away your energy tuning, the more distorted and asymmetrical the pattern becomes, hiding the precise direction and location.
Once you have a candidate origin, you can use the scanner to reconstruct a massively zoomed in view. If you aimed precisely enough, you will discover the stellar body. If there are a number of stellar bodies in relative close proximity to your focus, you may need to repeat the process to isolate individual signals.
As you locate and identify stellar bodies their emissions are filtered out, instead becoming markers on the energy range, making it easier to find the remaining bodies. It's at this point in that you will gain the “first discovered” tag, rather than having to physically visit the planet (you still need to sell the data at a port to gain the tag). All current first discovered tags will remain.
Importantly, when you uncover a planet using the discovery scanner, as well as being informed of the resources available on it, the presence of unusual locations, such as Guardian sites, will also be revealed. However, their precise location won’t be shown until you have mapped the planet with the detailed surface scanner.
Unidentified Signal Sources
Along with the Exploration update, we are improving the way that USSs work. USSs will now spawn throughout the entire system when you first enter it. This enables you to use the new exploration tools to find USSs throughout the system, not just in the area around you. You can still interrogate nav beacons to find the locations.
Whilst USSs do still have a decay time, the timers have been increased to allow you time to find and fly to the ones you are interested in. The decay time is also now displayed when targeted. Signal sources still obey rules determining where they can appear within a system, and mission critical signal sources will still be highlighted to differentiate themselves once located.
