NIST Demos Transfer of Time Signals over Wireless Optical Channel

May 6, 2013 - By

By bouncing eye-safe laser pulses off a mirror on a hillside, researchers at the National Institute of Standards and Technology (NIST) have transferred ultraprecise time signals through open air with unprecedented precision equivalent to the “ticking” of the world’s best next-generation atomic clocks. Described in the April 28 issue of Nature Photonics, the demonstration shows how next-generation atomic clocks at... read more

Advanced Navigation Releases Dual-Antenna GNSS/INS

May 2, 2013 - By

Advanced Navigation has released Spatial Dual, its new dual-antenna GNSS/INS. Spatial Dual is a ruggedized miniature GPS-aided inertial navigation system and AHRS that provides accurate position, velocity, acceleration and orientation under demanding conditions. It combines temperature calibrated accelerometers, gyroscopes, magnetometers and a pressure sensor with a dual-antenna RTK GNSS receiver. These are coupled in a sophisticated fusion algorithm to deliver... read more

On the Road under Real-Time Signal Denial

May 1, 2013 - By

Emerging GNSS applications in automobiles support regulation, security, safety, and financial transactions, as well as navigation, guidance, traffic information, and entertainment. The GNSS sub-systems and onboard applications must demonstrate robustness under a range of environments and varying threats. A dedicated automotive GNSS test center enables engineers to design their own GNSS test scenarios including urban canyons, tunnels, and jamming sources at a controlled test site. read more
