[Lex Computer & Tech Group/LCTG] Boston Dynamics vs football halftime

Mon Oct 21 13:26:03 PDT 2024

All,

This is a very nice demonstration of a rapidly advancing technology based
on what is known as real time kinematic (RTK) positioning combined with
Global Navigation Satellite System GNSS [generic form of GPS]

see for example
https://www.quectel.com/library/rtk-correction-services-white-paper/?creative=714667537585&keyword=gnss&matchtype=b&network=g&device=c&gad_source=1&gclid=Cj0KCQjw99e4BhDiARIsAISE7P9bWsmOeKo6dZy8b7apWcdqS4EqeF8VNSGLhicaAM11dTq5TgTW8T8aAiRHEALw_wcB

Although GNSS offers ubiquitous coverage worldwide, its accuracy can be
> hindered in some situations – signals can be attenuated by heavy
> vegetation, for example, or obstructed by tall buildings in dense urban
> canyons. This results in signals being received indirectly or via the
> multipath effect, leading to inaccuracy, or even blocked entirely.
> Unimpeded GNSS positioning in all real world scenarios is therefore
> unrealistic – creating a need for supporting technologies, such as real
> time kinematic (RTK) positioning and dead reckoning, to enable
> centimeter-accuracy for newer mass-market IoT devices.

PS: -- Perhaps we could arrange [one way or another] to have a talk on this
for LCTG
