Multiple beacon pulse beam rangefinder for space travel

When measuring space between stars and planets, a suitable precise long distance rangefinder must be utilized. Multiple beacons should be used for measurements. The beacons are used for specific pulsewave emissions. The emissions are isolated as follows: [1]second spaced emissions [2]minute spaced emissions [3]hour spaced emission [4]day spaced emissions [5] week spaced emissions [6] month space emissions [7] year spaced emissions Pulse beams are measured from earth. time versus space is accurately measured by pulse signal comparators. To be extremely accurate, a speed measurement device on the space vehicle is necessary
