From RF to I/Q: Why GNSS Receiver Testing is “Shifting Left”

“Shift left” has become a common phrase in the software industry, but not so much – yet – in GNSS receiver development. It refers to the stage of the development cycle at which testing is carried out. In the past, software applications were typically tested only after they’d been written, meaning that whole systems had […]

As new GNSS receiver standards emerge, developers face new test challenges

As new GNSS receiver standards emerge, developers face new test challenges Despite the widespread use of GNSS systems in all industries, it is a technology area where some applications remain loosely regulated. Today, GNSS receiver manufacturers and integrators are only affected by a handful of standards – and often only when designing solutions for very […]
