Rhinozherous Posted October 6, 2021 Posted October 6, 2021 Hello! In the attached track I tried to hit a tank with JDAMS. Alltough I aim at the ground below the tank the bombs miss 2 times... the third one hits. Did I do something wrong or is there a bug wiht JDAMS? Thank you F16 JDAM.trk i7-14700KF 5.6GHz Water Cooled /// ZOTAC RTX 4070 TI Super 16GB /// 32GB RAM DDR5 /// Win11 /// SSDs only DCS - XP12 - MSFS2020
Solution Enduro14 Posted October 6, 2021 Solution Posted October 6, 2021 haven't watched the track so forgive me if it shows it. But did you use the laser range finder in tgp to confirm the coordinates? Tgp by itself wont be accurate enough for a jdam drop on target. So always laser range it and its more precise. Been doing same SOP with the Hog for years and seems to be the way. Intel 8700k @5ghz, 32gb ram, 1080ti, Rift S

Thank you F16 JDAM.trk 4 MB · 0 Downloads The track is rather large, but watched it anyway. If I saw that correct, you did not lase prior to dropping the JDAM. This will enable the laser rangefinder on the TGP for a more precise target location. It doesn't really matter if you point at the tank or the ground at that steep angle, but laser rangefinding does. You do not need to lase after the bomb has been dropped, but JDAM's are more precise if you use the laser rangefinding BEFORE you drop for a second or so. Note the little jump in coordinates after lasing on the TGP.

Thank you F16 JDAM.trk 4.07 MB · 2 downloads I´d say neither. If you Google GBU-38 + CEP you´ll find that the JDAM is supposed to hit inside 5m, best case scenario. Generating TGT Coords with your TGP is not best case scenario, still in DCS it mostly does hit pretty close. So 33% is actually pretty good IMO.
StevanJ Posted October 6, 2021 Posted October 6, 2021 I think the bigger problem is seeing that first target take the bomb on the chin, spit a countermeasure, chill, and say 'sup'.. 1
Ignition Posted October 6, 2021 Posted October 6, 2021 Does the spi update after using the laser? I thought it didn't update.
Frederf Posted October 7, 2021 Posted October 7, 2021 It should yeah. If you see a "T" on the HUD instead of an "F" or "B" then you're getting a laser rangefinding SPI.
Nealius Posted October 7, 2021 Posted October 7, 2021 Does the laser rangefinder work beyond the 8.4nm hard-coded laser limit in DCS? 1

Though to be real, there are bunch of issues with lasers and different generations of TGPs same with different "kinds" of lasers i.e. designator vs LRF, vs pointer. NONE of that is modeled in DCS. Part of what you read about with earlier pods (and one of the reasons they talk about "altitude" with TGPs) is that the early NdYag lasers would undergo HV breakdown at high alts. This was corrected in later model pods by using more modern lasers as well other issues like spot-jitter (also not modeled in DCS). Not to mention the various issues with JDAM's and CEP and TOO coordinates in general. Which also is pod dependent to a large degree, though we don't have this combo in DCS.

ED Team BIGNEWY Posted October 7, 2021 ED Team Posted October 7, 2021 Hey the track was a little long but I am not seeing a problem, my own test seem fine. If you want to test and produce shorter track replays showing a problem I am happy to take another look. thanks Forum rules - DCS Crashing?

Rhinozherous Posted October 7, 2021 Author Posted October 7, 2021 Indeed I did not lase before the drop! So I think it is a combination of my fault and realistic hit area!

deltatango Posted October 11, 2021 Posted October 11, 2021 Hornet driver here just picking up the Viper. Is this an F-16 specific thing? JDAMs work just fine in the F-18 without lasing.

JDAMs work just fine in the F-18 without lasing. Depends on your target size, larger targets are Ok. Don't know about the Hornet, it is the only teen fighter I don't have.
