INS and GPS.
Hi everyone,
I found a technical interview question burried in one of the threads, can't remember which, from the Interview and Jobs section of the forums. The question is the following: What is an INS and how does it differ from a GPS? I have read through my ATPL material and understand the first part of the question but I can't expand any further on the second part. In general terms an INS is a self-contained navigation system which requires no external source input whereas a GPS does (i.e. that of satellites). Can anyone else add or expand on the possible differences?
Thanks.
