La DARPA bosse (ou fait bosser) dessus depuis 2007 et le projet avance régulièrement.
Et tout est intégré (on va quand même pas s’amuser à rentrer le vent… la première phase du projet portait justement là dessus).

During the project’s first phase, which started in 2007, Lockheed developed a down-range system that measured average crosswind; range to target; spotter scope position; air temperature, pressure, and humidity; and more, according to Military Aerospace. Using all those variables, it calculated the ballistics for a .308 bullet at ranges as far as 3,600 feet.
While that’s impressive, the system was too heavy and unwieldy, and it couldn’t be used with standard rifle scopes.
The phase two design will be more compact and able to operate in real time and over longer distances.
It will measure atmospheric conditions, account for the weapon’s maximum effective range and include GPS coordinates. It’s also supposed to communicate with the rifle scope, informing the gun itself of the aim point offset and expected crosswind.

One Shot XG

This next-generation One Shot envisions a compact observation, measurement, and ballistic calculation system mountable on either the weapon or spotting scope. The system developed will measure all relevant physical phenomena that influence the ballistic trajectory and rapidly calculate and display the offset aim point and confidence metric in the shooter’s riflescope. The system will provide the ability to see the aim point on the target in either day or night to enable rapid target identification, weapon alignment, measurement of range to target and the crosswind profile. The XG system seeks to exploit new technologies to operate over a range of visibilities, atmospheric turbulence, scintillation and environmental conditions.
One Shot XG Phase 2 began in March 2013 and is expected to be complete in Spring 2014. If successful, One Shot XG would lead to limited rate production with the military services taking on the requirement and acquisition role for future procurement.
