Engineers tasked with integrating positioning technologies into products are now commonly required to define and implement new regimes to ensure that the chosen GPS, GNSS and hybrid positioning systems function to ever tighter specifications. This can be challenging. Test equipment manufacturers publish specification data, often with little interpretation to give meaning to the numbers. But for device manufacturers, the development consequences of choosing the wrong test equipment—and running ineffective or inconsistent tests—can be severe. This white paper will give engineers clarity, summarizing the key areas and outlining some common pitfalls surrounding testing procedures and apparatus.
