SharpeXB Posted August 24, 2014 Share Posted August 24, 2014 so far I've missed 4 targets in a row with these. afaik I'm doing everything right, there's not much to go wrong with a JDAM. set the target as your SPI and hold the weapon release in the cue. but it's missing every time i9-13900K @ 6.2GHz oc | ASUS ROG MAXIMUS Z790 HERO | 64GB DDR5 5600MHz | iCUE H150i Liquid CPU Cooler | 24GB GeForce RTX 4090 | Windows 11 Home | 2TB Samsung 980 PRO NVMe | Corsair RM1000x | LG 48GQ900-B 4K OLED Monitor | CH Fighterstick | Ch Pro Throttle | CH Pro Pedals | TrackIR 5 Link to comment Share on other sites More sharing options...
Flagrum Posted August 24, 2014 Share Posted August 24, 2014 Track? Link to comment Share on other sites More sharing options...
Sabre-TLA Posted August 24, 2014 Share Posted August 24, 2014 (edited) Here is a step by step guide. Make sure you have full EGI alignment, that your TGP is set as SPI and that you hold the release button for at least 2 seconds (IRL that sends the GPS coordinates to the bomb before release).

txmtb Posted August 24, 2014 Share Posted August 24, 2014 Track would help as Flagrum pointed out. Helps to laze the target when you create the SPI. If not the TGP is looking through the target at the ground behind it, depending on slant angle to target, the error can be quite a bit.

Sabre-TLA Posted August 24, 2014 Share Posted August 24, 2014 This thread has a good discussion about lasing or not. I don't lase with JDAMs and usually don't have a problem hitting the target though there is some evidence that lasing can help (in the thread above).

SharpeXB Posted August 24, 2014 Author Share Posted August 24, 2014 Does the CDU wind correction affect anything with LGBs or IAMs? i9-13900K @ 6.2GHz oc | ASUS ROG MAXIMUS Z790 HERO | 64GB DDR5 5600MHz | iCUE H150i Liquid CPU Cooler | 24GB GeForce RTX 4090 | Windows 11 Home | 2TB Samsung 980 PRO NVMe | Corsair RM1000x | LG 48GQ900-B 4K OLED Monitor | CH Fighterstick | Ch Pro Throttle | CH Pro Pedals | TrackIR 5 Link to comment Share on other sites More sharing options...

If not the TGP is looking through the target at the ground behind it, depending on slant angle to target, the error can be quite a bit.This is true. The only thing is that the laser has to be on at the point of release because once you turn off the laser, the SPI reverts to being behind the target. Once the JDAM has dropped, you can turn off the laser. Of course some people don't like to lase at all because it can alert ground units of an impending strike. I think this is more the case in Combined Arms and not so much with AI units. Link to comment Share on other sites More sharing options...
Sabre-TLA Posted August 24, 2014 Share Posted August 24, 2014 I don't think there is an effect with the GPS guided munitions, however there are Wind Corrected Munitions like the CBU-103 which don't use GPS but uses INS and steers itself to the target. LGBs can be effected by wind. Even with the laser aimpoint it must be corrected for winds. Adjust the laser aimpoint one foot upwind per knot of wind determined. For strong surface winds you may even have to aim off the target to record a hit. LGBs require a minimum of 8 seconds of guide time or the bomb won't guide to the target.

SharpeXB Posted August 24, 2014 Author Share Posted August 24, 2014 The laser must be it. I'll try that. I am designating these SPIs at a higher slant angle. I try aiming for the wheels. i9-13900K @ 6.2GHz oc | ASUS ROG MAXIMUS Z790 HERO | 64GB DDR5 5600MHz | iCUE H150i Liquid CPU Cooler | 24GB GeForce RTX 4090 | Windows 11 Home | 2TB Samsung 980 PRO NVMe | Corsair RM1000x | LG 48GQ900-B 4K OLED Monitor | CH Fighterstick | Ch Pro Throttle | CH Pro Pedals | TrackIR 5 Link to comment Share on other sites More sharing options...

I think, GPS or INS guided weapons might be affected as well as the flight envelope in which the weapon can reach the target would change if wind is present. Probably onle relevant at the margins of the envelope (min or max range). Would be interesting to test this ... hrm... Link to comment Share on other sites More sharing options...

Once the bomb falls off the rack, you can turn off the laser and forget about the bomb. Link to comment Share on other sites More sharing options...
kontiuka Posted August 27, 2014 Share Posted August 27, 2014 Or set to "Auto" in the weapons configuration page.Mmmm, not really applicable for JDAMs. That's more for guiding LGBs right to the target. I think of it as ... JDAMs, lase before release. LGBs, lase after release. Of course, a lot of people say you don't have to lase at all with JDAMs and there's some truth to that. I just do it cause I like to push lots of buttons.;) Link to comment Share on other sites More sharing options...
SharpeXB Posted August 28, 2014 Author Share Posted August 28, 2014 Turning on the laser did the trick.

will- Posted August 28, 2014 Share Posted August 28, 2014 No, the SPI reverts back to its pre-lased position. You need to have the laser on at time of release for the JDAM to have the lased coordinates. Once the bomb falls off the rack, you can turn off the laser and forget about the bomb. You can get the same effect by creating 2 mark points... one from just area Mark point A. Now lase then create Mark point B. You will have a more precise shot w/ the latter.
