Hyperspace pinging

Having spent considerable time in hyperspace, humans have discovered a means of changing the quantum wavefront to emit a ping through hyperspace. The ping is charged with a certain formation that allows the ping to return back to the warpcraft, thereby locating it. Additionally the use of the hyperspace microwavefront means that it will be able to travel at the same speed as gravitic drive-equipped warpcrafts. This enhances the detection range of such warpcraft by 100,000x. However, being novel, it is also an incredibly costly device.
