The basis of all precision positioning and navigation is precision timing. Timing comes first. GPS Time is defined on the basis of a set of atomic clocks orbiting aboard the satellites and on the ground in monitoring stations; similarly for the other GNSS systems.

Leuven, Belgium-based Septentrio, a global supplier of high-accuracy positioning technology for demanding applications, unveiled this week AsteRx SBi, a new housed GNSS/INS receiver. Within its rugged, waterproof enclosure a high-performance GPS/GNSS is coupled with an industrial-grade inertial sensor to provide high-accuracy, reliable positioning and 3D orientation (heading, pitch, roll).

GMV has been chosen for development of advanced safe and precise positioning technology for a new generation of autonomous vehicles. Last week the Madrid, Spain-based company announced the award of an important contract for development of a precise satellite-based (GNSS) positioning system with integrity for the new generation of autonomous vehicles of the German carmaker BMW Group.

When the very first visitors to INTERGEO passed through the turnstiles in Dortmund’s Westfalenhallen exhibition centre on the dot of 9 a.m. on August 23, 1995, even the most wildly optimistic observers could hardly have imagined the trajectory this fledgling event was embarking upon. Although the geodesists conference was a firm fixture in this specialist field, the trade fair—until then billed as the “accompanying exhibition”—with its 185 exhibitors was really quite modest, despite having grown considerably, compared to the event held in Mainz in 1994.

The Chinese are closing in on the completion of the BeiDou constellation with 39 satellites now on-orbit and more launches planned, an official told a conference on aerospace technology innovation.
Yang Jun, deputy director of China’s Satellite Navigation System Management Office, told attendees at the Shanghai event that the plan is to loft five to seven more satellites into place this year and another two to four in 2020, according to the Xinhua news agency.

The U.S. National Aeronautic and Space Administration (NASA) has activated an orbiting ultra-precise atomic clock orbiting aboard a spacecraft provided by General Atomics Electromagnetic Systems. If the clock performs as well in space as it has in the lab, losing only one second every 10 million years, the technology could enable far-reaching deep space missions—and improve the accuracy of GNSS timing and positioning.
