Faster than real-time GNSS receiver testing

The new GNSS systems available present possibilities and challenges in the design of modern GNSS receivers. As a part of this challenge, receiver testing is always very important aspect. Careful testing procedures tend to be slow and tedious. In this paper we present a method for speeding up the test process without limiting the testing capabilities. The proposed method is only applicable to testing performed on recorded GNSS data. In this method the recorded data is streamed as fast as possible, without being bound by normal GNSS data rates. Utilizing this kind of architecture on a GNSS receiver can cut the time spent in the testing process by 70% or more, depending on the computational performance of the GNSS receiver platform. Speeding up the test phase of a GNSS receiver is beneficial for both academic and commercial entities, allowing time to be spent on other tasks.
