fylzz Posted September 7, 2021 Share Posted September 7, 2021 The circle around contacts on the HMD is quickly drifting away from the real location of the object. When the object exits and then enters the viewport of the HMD again the position is correct again and then drifts away quickly again. HMD alignment has been properly done on the ground. I have a track but it is 10MB (only like 10 minutes of gameplay with cold start). How can I transmit this file to you ? I suspect same behaviour with ground diamond but have no track for this. 1 :Ryzen 5800X | RTX3090 | 32Gb RAM | Nvme SSD Gen.4 | Reverb G2 | Virpil WarBrd Base | Constellation Alpha Grip / Virpil CM3 Throttle Link to comment Share on other sites More sharing options...

Scotch75 Posted September 14, 2021 Share Posted September 14, 2021 I thought I heard or read a comment somewhere that this behaviour was to be expected due to the slight delay in data link information and gps updates. I'm not 100% sure though.Cheers!Sent from my SM-G950F using Tapatalk W10 Home 64Bit, Intel Skylake I5 6600K 3.50GHz, ASUS ROG Stryx Z270F MoBo, 32GB G.Skill RipJaws V DDR4 3200 RAM, Samsung 960 Pro 512GB M.2 SSD (OS), Samsung 850 Pro 512GB SSD, 2TB Seagate SDHD, 2TB WD Green HDD, GALAX GTX GeForce 1070 EXOC Sniper White 8GB VRAM Link to comment Share on other sites More sharing options...
ED Team BIGNEWY Posted September 15, 2021 ED Team Share Posted September 15, 2021 Yes there is about a 12 second delay in the information, I have asked the team to take a quick look, but my feeling is this is correct as is. thank you Forum rules - DCS Crashing?

Swift. Posted September 15, 2021 Share Posted September 15, 2021 It is odd that the PPLIs don't extrapolate like tracks do. Especially when you think about all the MSI stuff going on... 476th Discord | 476th Website | Swift Youtube Ryzen 5800x, RTX 4070ti, 64GB, Quest 2 Link to comment Share on other sites More sharing options...

jackdaw Posted September 15, 2021 Share Posted September 15, 2021 @Convexrook so do you align the HMD twice before takeoff? Link to comment Share on other sites More sharing options...

84-Simba Posted November 16, 2021 Share Posted November 16, 2021 Strange ... sometimes it does, sometimes it doesn't. I always do the same cold start procedure so I align pretty much everytime at the same moment. Could it be related to the position of the donor ?

BlackRook Posted February 10, 2022 Share Posted February 10, 2022 I get this too, watching this thread to see if this is a bug or not. Will try a few different alignment timing changes in the startup procedure. I tend to turn on DL/IFF/TACAN last. Link to comment Share on other sites More sharing options...
Ourorborus Posted February 10, 2022 Share Posted February 10, 2022 Some irregular drift in datalink is to be expected, As Big Newy stated, a datalink contact can be up to 12 seconds old. How long depends on many things and will vary constantly. Your own display shouldn't extrapolate a PPLI as this will potentially add further error to the position. Remember the PPLI is simply a position sourced from another aircraft, and has already been subject to track filters/extrapolation etc. Think of datalink as a type of LAN. The protocols/language differ but the concept is the same. Instead of Cat5/6 cable or wifi it is linked over crypto radio. So, 1. Aircraft A (AWACS/wingman etc) detects a track, the track is subject to interpolation to account for RADAR update rate. (e.g. time for AWACS RADAR to complete a 360degree sweep, wingman may have a wide 6 bar sweep etc....) 2.The information is encrypted. Anyone who has ever used crypto radio voice will know there is noticeable delay in transmission. So the data may be 1-2 seconds old before it even leaves the donor. 3. The data is broadcast over the network. This is a biggie. Unlike your home LAN, the network is subject to atmospherics, antennae shielding, changes in range... the list goes on. Try maintaining a wifi network between 10 cars on the highway and you will get the idea..... Now make those cars maneuver abruptly in 3d and fill the electromagnetic spectrum with multipe RADAR, UHF, VHF, ECM etc etc... 4. The data is received, decrypted and displayed in aircraft B (you). 5. Like all networks this data is constantly being refreshed, updated and transmitted to/from all participants... with so many variables is impressive that the delay is only up to 12 seconds.

Think about data sourced from AWACS. F/F link as a 3x faster refresh rate, and I would think the PPLI data would be for accurate the closer you get. Having a 12 second delay for all information is wrong. Link to comment Share on other sites More sharing options...
