    Gimbal distance and Speed Range Estimates using Lines of Bearing and/or DCS

    It's jittery because you are only SLAVING to the RADAR track, try obtaining an optical auto track after you SLAVE. For bonus points remove the SLAVE afterward but maintain the autotrack.

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    It just occurred to me that I found this link when I was searching for how passive ranging might occur from the ATFLIR only Might some of it's theory be applied to Gimbal? https://www.mathworks.com/help/fusion/ug/passive-ranging-using-a-single-maneuvering-sensor.html I'm not a mathematician...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    I used to play the PC game Battlefield 2 to a decently high level (winning the "European Cup" of Battlefield 2). Most of the skill in being good at that game was essentially reaction speed, practise, full knowledge of the games built in systems and prediction of human behaviour as well as "meta"...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    Chris Lehto alludes to it in his Go Fast video. There's a thread about the issue here https://www.metabunk.org/threads/atflir-and-range-information-radar-laser-passive-range.11809/#post-251396

    GoFast : is the background moving relatively to the movement of the jet ? Or the camera only ?

    When not tracking the system keeps the camera pointing relative to the jet, once the object is being tracked the pod gimbal starts moving to keep the object central to the camera system and the jet. So if the jet is moving and the object isn't the camera has to move and vice versa, if the...

    https://forums.vrsimulations.com/support/index.php/A/A_Forward_Looking_Infrared_(FLIR)#Inertial_LOS_Mode When the FLIR is in the Inertial LOS Mode, the MC maintains the FLIR LOS at a constant pointing angle with respect to the inertial reference plane. TDC slewing with TDC priority to the FLIR...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    I hear that is a fucking drone It seems they have an L+S track designated, the FLIR is showing something on both of their MFD screens, the pilot is asking the WSO "that's not L+S?" i.e. is the FLIR pointing at the track they have set as L+S. He says that is L+S dude. I presume the WSO is...

    ATFLIR and range information (RADAR/LASER/Passive range?)

    It's displayed in A/A mode, if it's enabled it's 'boxed' ie surrounded by a rectangle indicating enabled, it's enabled by pressing a button that is next to the word on the outside of the display. Note L+S is boxed if the SLAVE is to the launch and steer target, slave is boxed if it's slaved to...

    ATFLIR and range information (RADAR/LASER/Passive range?)

    The main reasons discussed are 1. If they had a RADAR lock why not slave the ATFLIR to it? Rather than slew on the TDC and use the box to get autotrack, you would almost use SLAVE certainly do this in a real situation, however the nature of the chat could indicate they were playing/testing the...

    ATFLIR and range information (RADAR/LASER/Passive range?)

    It's hard to know for sure though, the only mention I can find to support passive ranging is some posts on the sim forums at the moment if it is inaccurate i wonder if it would displayed as matter of factly as it was in go fast. I lean towards it being the radar given we know it can provide a...

    ATFLIR and range information (RADAR/LASER/Passive range?)

    In the "Go Fast" video when the object tracking starts 2 figures instantly appear on the MFD video screen these are: RNG and V/C which are thought to show range in nautical miles and closing velocity in knots. These figures were claimed by the TTSA to be the range and closing velocity from...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    I agree with him but on ATFLIR LTD/R would flash, It's my theory that in Go Fast the range comes from a ATFLIR LOS correlated RADAR track.

    F-16 Pilot Chris Lehto's Interpretation of the GoFast footage [Focus, Parallax, Inaccurate Range]

    I think you can turn on the laser for A/A if you want but it's never used in practice as it's not accurate for A/A if it were firing the LTD/R text would flash. As in I don't think the range displayed in Go Fast is an inaccurate laser range because the laser is not firing. I think the range...

    NYT: GIMBAL Video of U.S. Navy Jet Encounter with Unknown Object

    The whole plane could bump at that point, turbulence, the claim isn't that every movement on the image is a ATFLIR rotation alone it's that ATFLIR major rotations can cause physical bumps to the camera system. So the fact that the rotation correlate with bumps is a sign that something physical...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    We have discussed range in the Go Fast video, the manual says that range is provided by the RADAR. Raytheon own a patent for programmatically estimating distances based on a known image database, but this is not mentioned in the ATFLIR manual. It's possible it's part of an IRST system they...

    F-16 Pilot- Chris Lehto analyses Gimbal footage

    The bumps are the mechanical components of the ATFLIR moving as it physically moves parts of system, they correlate with the rotation because the rotation and the bumps are part of the same thing, a movement of the system as it avoids gimbal lock. The system tries to avoid doing this type of...

    "LITENING AT, is in production and was fielded in 2003" There are a lot of versions so perhaps I'm wrong or this is not considered old.

    Although the Wiki says normally carried on one of the fuselage hardpoints otherwise used for AIM-120 AMRAAM missiles So that could indicate L or R but the manual says Left specifically.
