Spirent solutions help NTT and Furuno develop pioneering multipath mitigation algorithm for GNSS timing receivers

Spirent solutions help NTT and Furuno develop pioneering multipath mitigation algorithm for GNSS timing receiversA 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.

To counter these issues, NTT developed a multipath mitigation algorithm for GNSS timing receivers, and Furuno implemented the algorithm in their products.

Find out how Spirent’s solutions helped solve this challenge using realistic multipath simulation in the lab.
