Although there is no specific product standard for EMC in GNSS receivers, testing for immunity to electromagnetic interference has to be an essential part of the product development process. Any receiver designed for low-level signals will inevitably be susceptible to electromagnetic interference. And GNSS receivers inevitably are required to operate reliably in areas where they will be subject to any number of sources of interference. These range from natural phenomena such as solar ra...

It goes without saying that any RF device as sensitive as a GPS receiver will be inherently vulnerable to interference. Clearly, care needs to be taken at both the design and integration stages to minimise interference effects. But what interference sources need to be considered? And how do you know if your receiver can deal with them? Most potential sources of interference are obvious and predictable: The effects of fixed-frequency transmitters for TV, radio and the like can easily be modelled...
