Ybbor Notlimah	Posted - 2007.05.08 18:31:00 - [421] The full formula to calculate Signal Strength is: Signal Strength = (Probe Sensor Strength * (1 + Level of Astrometric Triangulation * 0.05) / 100) * (e^-((Target Range / Max Range)^2)) * (Target Signature Radius / Target Sensor Strength) How does scanning mission runners effect the formula?
Amberes DtoR	Posted - 2007.05.12 21:00:00 - [422] Very Nice Guide, thank you.
Usul78 Orcus Inferno	Posted - 2007.05.14 09:02:00 - [423] I've recently noticed a problem with scan probing while using a recon scan probe launcher and snoop probes. I've been probing for over a year and have worked out how to do it very sucesfully. The problem i've noticed is that I do a scan for a ship which I know is in space and within the range of the probe. The probe, as it should, gives a result and shows the strenght of the signal is always over 1 (2.6 to more accurate) and shows the distance to the ship and as its a snoop probe shows the accuracy as 0km. When I warp to the ship I breifly see it in my overview and it disapears, as if I've overshoot the location by a few thousand Kilometers. The distance now says something along the lines of 2-8 thousand Km. I redo the scan and i'm now given a distance similar to my original distance, but not the same. It apears as if either the accuracy is being incorrectly displayed and the snoop probe acts like a less acurate one (with a 2-8 thousand Km accuarcy), or the location of the ship changes after each scan. Has anyone else noticed this, or is this some new change that i'm not aware of? If this is not a recent change then I must assume it to be a bug. I've spoken to someone else who has just recently started probing for ships and he said he's had this also, but assumed it was due to a low skill level. I have everything set to 4 or 5 in relation to all relivant skills and have never experienced this in over a year of frequent probing. P.S. I'm using the probes correctly. I've tried with 2 seperate ships in 2 seperate locations. I've tried using multiple probes. I've logged off and back on again to try agin with the same result. My skills are either at level 4 or 5 respectively. I'm using the correct probe and launcher. Please can someone help shed a light on this problem. Thanks.
Znekkie	Posted - 2007.05.14 19:26:00 - [424] I also have this problem with probing. My skills are all on 4 so normaly i have to find it. I launch a snoop probe and get a result of 0 m but when i warped in i didn't see anything. The ship appears on overvieuw during warp (most off the time at 40000km) but when i stop its gone??? i scan again and again but never get to the ship. I have also tried with sift probes to see if that works, and i also get a result on 0m but no ship when i warp there. I just got my skills right and did some exploration and it worked but ship probing does not work for me. I do everything as in this guide: use the right probes/range Can someone please tell me if its a bug or something i do wrong. Grtz Znekkie
Usul78 Orcus Inferno	Posted - 2007.05.15 13:05:00 - [425] Sounds like the same problem as me. As its not just myslef and two other people have now confirmed the exact same problem we have to assume its a bug. I can't find any confirmation from CCP, or any other mention of this problem on the forums so if anyone does have any further information or have done some more conclusive testing then please let us all know. I've put in a petition explaining the problem and given them the link to this forum post. I hope CCP will give us more information soon, or even better, completely fix the problem.
Sprzedawczyk	Posted - 2007.05.24 23:45:00 - [426] " Signal Strength decides how large the chance is that the target will show up on a given scan and also effect accuracy. A Signal strength of 0.5 means 50% chance, 1.0 or more give 100% chance etc." You say...yet I had multiple situations where sig strenght 1.1 required average of...10 scans. so, bug or wrong guessing?

If the target is inside a deadspace field (mission for example) the effective signal strength is divided by a large number (I think 100 but not 100% sure) BUT the scan window will still display the unmodified signal strength. This is probably what you are seeing. ---------------------------------------- A Guide to Scan Probing in Revelations
Sprzedawczyk	Posted - 2007.05.26 18:13:00 - [428] I pinpointed the issue, now awaiting t2 bpos as token of appreciation from ccp:P Srsly. The problem was nerfing of signal strength when you have selected say quest and sift probe (even though they don't overlap!!!) - signal strength gets nerfed to hell, but gui still shows it's being 1+.
Paul 3Jane	Posted - 2007.05.28 11:06:00 - [429] Is anyone still getting the 'flyby' bug or is scanning now working as advertised. I started playing with scanning a while back and I to was getting a 0KM range with a signal strength over 1.0 but as the poster above said I would fly straight by the target ship. It would appear for a second on overview and then go. At the time I put it down to crap skills but I now have a Covert ops pilot training up for scanning and am concerned that once again I am wasting my time training up skills that no longer work or do not work as advertised (Blockade runners was the other one) Any input ?
Kua Immortal RSP Enterprises	Posted - 2007.05.29 14:32:00 - [430] Edited by: Kua Immortal on 29/05/2007 15:26:23 You know what would be really cool? A spreadsheet where you can plug in your skill levels, the attributes of the ship (with a modifier if it is in a complex or mission) and its distance and the attributes of the probe you are using and it will calculate the signal strength and accuracy you can expect. I am going to look into it, but I am no excel expert. Even better where it compounds with other ships and.or (sigh why do my slash and apostrophe keys bring up the quick find box - answers on a postcard) drones to bring up a likelihood of a result. That is starting to sound more complex however :P. EDIT: Fantastic guide btw. To anyone wanting to start probing ships down I HIGHLY recommend you read the exploration guide that is also stickied in this forum. Exploration probes are fab for finding peeps in missions. Ooops I've said too much . EDIT2: I chatted to someone in your corp (possibly your alt, IDK) who said that drones are definitely subject to the DEDspace modifier, can you confirm that? :P EDIT3: OK it was easy enough for one ship. Although the sheet is pretty untidy :P.

Hoshi Blackguard Brigade Phalanx Alliance	Posted - 2007.06.05 13:04:00 - [431] Finally got time to figure out how multiple probes effect each other. There are some final details to figure out but the most important work is done. When adding a second probe to the scan it will cause interference. It doesn't matter where this second probe is placed, it can intersect over the target or be placed several 100 au away, it will still cause the exact same amount of interference. The amount of interference is based on the range between the probe being interfered (the first probe) and the target. The shorter the range the less the interference. At close to max range for that probe the inteference is 30%, at 0 range it's 2.5%, it's then linar between these points. Let's do an example: Probe A, a snoop probe, strength 20, range 5. Probe B, another snoop probe, strength 20, range 5. Target T, a ship with signal size 5. Probe A is placed 4 au away from target T. Alone the strength would be 0.52. Now we place Probe B 100 au away, it will now cause inteference for probe A of 25% (base on the fact that Target T is 4 au from Probe A) so the new strength of the combined scan is now 0.39 If we place Probe B 4 au from Target T as well so the probes intersect over the target the strength from probe A is still 0.39, from probe B be it will be the same as A acts as interference and we then add these toghther for a combined strentgth of 0.39+0.39 = 0.78 ---------------------------------------- A Guide to Scan Probing in Revelations
Hoshi Blackguard Brigade Phalanx Alliance	Posted - 2007.06.05 23:08:00 - [432] Seems I was a bit premature, it seems multiple probes depending on placement can either cause Interference (like I described in the last post) or Amplification. If the probes are place so the target are positioned in between them you get interference BUT if you place both probes on the same side of the target you instead get Amplification of the same amount. Example: Interference Probe A -- 4 au -- Target -- 100 au -- Probe B Here Probe B cause interference lowering the strength by 25%. Amplification Probe B -- 100 AU -- Probe A -- 4 AU -- Target Here Probe B cause Amplification increasing the strength by 30%. I have yet to check what happens if you place them in different angles (a bit hard to make the BMs for that). ---------------------------------------- A Guide to Scan Probing in Revelations
Kua Immortal RSP Enterprises	Posted - 2007.06.09 11:19:00 - [433] Really nice work.
Weirwolf	Posted - 2007.06.09 21:32:00 - [434] ok here Goes: I ran a Multi-spec in my system, it came back with a Grav hit. so I positioned my Grav Quests with what I thought was good coverage of all the planets, (wish I knew how to upload pics) I did not get anymore hits on it , I tried like 15 scans with those, so then I got some Grav Combs and once again with good coverage took like 7 of them, ran another 10 scans and sure enough no hits, now am I being impatient here or ..... , so I'm asking the Guru's for advise here, I took some screen captures of my placement, so maybe if someone may be able to tell me how to do that, that would be awesome. I know it would help in my main question here. Thanx for Listening
Hoshi Blackguard Brigade Phalanx Alliance	Posted - 2007.06.09 23:06:00 - [435] I would suggest the exploration thread for that question but a simple question, did you get a hit with your quests before switching to comb? if you did not then you need to keep scanning with quest. A site can be upto 4 au away from any planet in any direction (up/down as well). There is no possible why that you could have covered that area with combs. Grav sites are the hardest ones to locate. Going thru 2-3 sets of quests before getting a hit is not unheard of. ---------------------------------------- A Guide to Scan Probing in Revelations
Weirwolf Capetola Enterprises	Posted - 2007.06.10 00:39:00 - [436] nope, I did not get a hit with the quests only the mult-spec, I will keep trying with the Quests....ty Hoshi , By the way thanx for the great guide, it has really helped out a fledgling explorer...........7
Weirwolf Capetola Enterprises	Posted - 2007.06.10 06:15:00 - [437] well I found it, It turned out to be Barren astriods but never the less,I'm hooked, once again Very good Guide. I applaud your work on it...till next time
MeestaPenni Gallente	Posted - 2007.07.04 15:39:00 - [438] Great thread with some very useful information. I'm sorry for asking what is possibly a stupid question. If I load my probe launcher with 20au probes, how do I then reload with 5au in order to "fine-tune" my scan results? I can unload to cargo, but attempting to reload only shows the previously loaded probes. Kinda' new at the probe scanning thing.

I can unload to cargo, but attempting to reload only shows the previously loaded probes. Kinda' new at the probe scanning thing. If you have them in your cargo they should show up if you right click on the probe launcher. Just like when loading ammo. Maybe you put the wrong probes in your cargo. Exploration probes (quest etc) won't fit in the recon launcher. ---------------------------------------- A Guide to Scan Probing in Revelations
Rush X Unidentified Flying Dutchman	Posted - 2007.07.20 23:00:00 - [440] thx for the info peeps

Aerinn	Posted - 2007.07.26 11:15:00 - [441] Has anyone seen the very simple ingame browser page that calculates scan times? It lets you select which ship you have, what level skills you have, and what rigs you have equipped, and then calculates your scan time. I used to have this in my bookmarks, but lost all my BM's due to a computer rebuild and I can't find it in my old bookmarks file in the game directory. I know the formulas for all of this, but somewhere I got a link to an in-game browser page that was very clean/simple, graphical, and useful. I think it was a calc on the D-Nightmare site, but I could be COMPLETELY wrong about that, and I can't find it there. Does anyone know what I'm talking about?
Kamir SarZak	Posted - 2007.08.02 19:27:00 - [442] Does anyone know if Observator Deep Space Probes are of any use ? All I have managed to pick up are ships (which is not what I want to do with these probes), and I have been using them for a while now. I have heard that there are sites that you can pick up with these probes that you cant with the usual ones. Does anyone know if this is true ? So far I have not been able to confirm it. Thanks. Kamir

Kamir Observator Deep Space Probe is used to find ships located in deep safe spots and for that it works just fine. All exploration sites are within 4au of a planet so there is no need for observators to find any of them. Note that the observator probe has such a low strength that you are talking of around 0.001-0.01% chance of picking an exploration site per scan. ---------------------------------------- A Guide to Scan Probing in Revelations

Niina Infinitus Odium The Church.	Posted - 2007.08.14 17:03:00 - [447] has probing been changed since i have no luck getting missions spots anymore :( used to get many NPC'ers thisway after revelations 1 patch, now i cant get a hit to a BS whit 100 try's :(

Or to put it a different way, is the chance of getting a hit still better than if you'd only placed one probe? Sorry for the late response, with the thread not sticked anymore I missed the new posts in it (reply notification please CCP?). It is possibly to reduce the total chance of finding the target by placing another probe. It will happen in 2 specific cases: 1. If the second probe is out of range of the target and placed so that the target is in between the probes. In this case the probe only creates interference as it's not in range to boost. 2. If the second probe is in range but is of a longer range/weaker kind. Depending on the exact probe types and placement it's possible for the second probe to create more interference than its boost to the signal. In practice you need probes at least 2 sizes apart, ie 5 au and 20 au or 10 and 40 au for this to happen. ---------------------------------------- A Guide to Scan Probing in Revelations

Ah ok, that's unfortunate. So "interference/amplification" doesn't have a maximum range? One of the real pleasures I've been getting from exploration is trying to get good overlaps, and it's a little sad to think in some cases all the effort has been and will be hurting my chances rather than helping them.

One of the real pleasures I've been getting from exploration is trying to get good overlaps, and it's a little sad to think in some cases all the effort has been and will be hurting my chances rather than helping them. Any recommendations? The problem with exploration is that you don't know where the target is, not even after getting the first hit do you know where the target is in relations to the probe. This makes it very hard to avoid/take advantage of interference/amplification. My suggestion for exploration is this. When placing quests just ignore it completely. A probe sitting at the other side of the system scanning another planet might end up increasing or decreasing the chance, just try to get as good coverage as possible and if you can/want to go for overlapping then do so. After the initial hit just use one probe, here trying to place more probes to get overlapping is more than likely to backfire and create interference instead. The practical uses of interference/amplification are more interesting with ship probing where you know where your target is in relation to your probes. ---------------------------------------- A Guide to Scan Probing in Revelations
