LetMePickThat Posted January 8, 2022 Posted January 8, 2022 (edited) Hi all, I've jumped back in the 16C after a long hiatus, and I'm trying to understant the AG radar modes. Smooth sailing so far, save for this little problem: there seems to always be a (quite large) offset between real and radar-given object positions. See for instance the image below, where I initially slew the radar to the target, sent the FTT to the TGP then corrected until the TGP was actually on the target. There's a significant difference between where both sensors think that the target is (and the TGP is right). I've tried to use CZ on both the pod and the radar, to no avail. Is there a way to correct this offset for TGP-free, radar-only weapon delivery? Thanks ! Edited January 8, 2022 by LetMePickThat
twistking Posted January 8, 2022 Posted January 8, 2022 to double check, maybe make a markpoint from the TGPs correct position, make markpoint SPI and CZ. Then check if there is still offset... My improved* wishlist after a decade with DCS *now with 17% more wishes compared to the original
Frederf Posted January 8, 2022 Posted January 8, 2022 The FCR and TGP are not dragging each other around properly. The TGP moves the FCR okayish but the FCR isn't moving the TGP at all. You're not doing anything wrong. The FCR isn't keeping the ground map picture correct throughout the scanning process. When the cursors move you can't trust the picture you see until slewing stops and then the next scan is applied. A slow sweep of the TGP across the terrain will only have the FCR picture correct the instant the sweep passes the crosshairs. At all other times it's out of date, like a periodically updated bread crumb trail. I'm guessing if you controlled TGP and read off the coordinates of a particular target and then controlled FCR and read off the coordinates of the same target that the numbers would match. Attacking with either sensor based on what you see in that sensor should be working fine. Moving one sensor and having the other follow (and having its video be useful) is what's not all the way there yet. 1
LetMePickThat Posted January 14, 2022 Author Posted January 14, 2022 (edited) Hello all, I saw that this thread got the cannot reproduce and missing track file header, so here is a track. Very simple flight, the goal is to drop two JDAMs on a static Il-78. The radar in air-to-ground mode is used, and as one can see this results in a large (0.5 nm) offset between where the radar thinks the target is and where the TGP shows it to be. A TGP correction is therefore needed to avoid bombing a random set of coordinates .5 nm away from the actual target.

Thing is, even in pure RDR AG bombing, when selecting the target right after a sweep, there is still an offset... See: RDRGNR_OFFSET.trk Edited January 14, 2022 by LetMePickThat 1 1
