Production testing is a vital task for manufacturing quality assurance. However, the device used must be tested for correct operation, which is not a simple task for GNNS applications.
Nowadays GNSS receiver chips are found in numerous products, from smartphones to satnav systems in car and quadcopters. Based on current trends, satellite navigation will likely be used even more in the future.
Production is typically indoors. Variable weather conditions make usage of the live satellite signal unfeasible since it doesn’t allow a repeatable final test. This is where a viable indoor signal generator becomes necessary.
