Creating the Ideal GNSS Testing Environment

While the real world cannot be fully re-created in the lab – there are just too many variables to account for – there are ways to significantly close the realism gap. Find out how to generate more actionable data for a greater proportion of your testing by bringing that testing into the lab.

"We have several GSS6450 units, used for multiple purposes, and are happy with them. The bandwidth and quantisation bits give a very good representation of the RF environment. Other positives for us are the user-friendly GUI, portability, and ease of integration into an automated test framework (via TCP/IP)."
