A 250-day experiment using a ring laser achieved unprecedented accuracy in measuring Earth's axial wobble (nutation and precession), surpassing previous gyroscope and ring laser technologies by a ...

For many centuries, the principle of triangulation - that is the geometric measurement using three-point relationships - has been relatively well known. In Europe, the land survey method established ...

The novel LIDAR ("light detection and ranging") system could have applications from precision manufacturing lines on Earth to maintaining networks of satellites in perfect formation, creating a giant ...

Able to measure in two axial directions, the Microgage 2D alignment kit from Pinpoint Laser Systems is useful for precision measuring, machine alignment, calibration, and other demanding industrial ...

Space. The final frontier. Unfortunately, the vast majority of us are planet-locked until further notice. If you are dedicated hobbyist astronomer, you probably already have the rough positions of the ...
