This is followed with the definition of trajectory correction using two kinds of course correction modules: one is devoted to range correction (drag ring brake) and the second is devoted to drift correction (canard based-correction fuze).
The total drag coefficient (body + drag ring brake), in case of range correction, is also shown in Figure 5.
In this work, the trajectory correction is obtained by using two kinds of modules, one is devoted to range correction (drag ring brakes, Figure 8) and the second is devoted to drift correction (canard based-correction fuze, Figure 9).
Range Correction. The concept of drag ring brake has been discussed by Hollis and Brandon , which replaces the standard fuze of conventional artillery projectile with trajectory corrector module, without changes within the ogive shape of the artillery projectile.
Although in FSA the second range correction
step neglects the space variance, this neglect will not decrease the image qualities of target 4 and 6 even with high squint angle.
If at close range correction
is of limited use, the longer the range the more important a precise evaluation of the shooter to target distance becomes to ensure optimal accuracy.
On clicking the Function button, the very first option gives you a flexibility to adjust highlights with the Dynamic Range Correction
mode and adjust shadows with the Shadow Correction mode.
Several programmes to develop range correction systems are known to be under development but only one need be mentioned.
Range correction principles can also be applied to artillery rocket systems.
Range correction systems are also under consideration for the MLRS, the Contraves Rheinmetall Enhancement Correction for Trajectories (known as Corect) being but one example.
With LAAS, a ground reference station at a primary airport will broadcast range corrections
to all aircraft within about 25 nm, and will even allow Cat III (autoland) accuracy, as well as surface movement guidance.
It would be ideal if range corrections
could be somehow combined with line correction to improve on-target accuracy that much further.
