Case Study

Shaping the future of 5G with Furuno

It’s widely accepted that simulation is the primary tool for testing GNSS enabled equipment. However, selecting the right simulator is not simple. The first port of call should be to check the feature list – does the simulator offer the functionality you require? After this, though, you will need to establish whether the simulator performs as expected. Failure to do so could have catastrophic consequences for your product, and even your business.

This eBook takes a look at some of the important performance characteristics that you need to consider, and that can make the difference between success and failure.

Protect your receiver against harmful multipath and obscuration

A 5G network architecture typically requires primary reference time clocks (essentially GNSS receivers) to be installed near clusters of short-range base stations. Many clocks will be installed at street level in built-up areas, rather than on top of towers or tall buildings as has been the case with 4G. Multipath signals abound in such locations, while the narrow view of the sky often limits the number of line-of-sight satellite signals available. Both issues can severely affect a receiver’s ability to maintain accurate time, to the point where network quality of service can be seriously impacted.



Modern cellular networks need accurate time signals from GNSS satellites to keep transmission in sync. With Spirent’s help, NTT and Furuno have developed an algorithm for GNSS timing receivers that eliminates the effects of multipath, dramatically improvi
