Are special GNSS receivers required for high-dynamic applications such as on fighter aircraft?
Yes — high dynamic applications do often require special types of GNSS receivers. When designing a GNSS receiver, many tradeoffs need to be made, and certain design decisions are necessary in order to be able to track during high dynamics. Several different factors can affect the ability of a receiver to maintain lock on the GNSS signal for a given level of dynamics, including the loop filter characteristics, oscillator phase noise, and oscillator vibration sensitivity. Each of these will be explained separately. (For the rest of John Raquet’s answer to this question, please download the complete article using the PDF link above.)
