Fundamental GNSS receiver characterisation

Conclusions
This Application Note describes the
fundamental performance parameters
that apply to all GNSS receivers.
These parameters must be optimised
at an early stage in a receiver design.
Optimisation requires suitable testing.
This Application Note shows that a GNSS
simulator allows you to develop tests that
optimise receiver design. SimGEN offers
very high resolution control of signals and
bit-level manipulation of data,
reproducing the most complex error
effects while its easy-to-use interface
allows straightforward tests to be carried
out with the same powerful modelling
taking place in the background.
It shows that there are no practical
alternatives to simulator testing in
situations where the receiver must
be tested while undergoing
high-dynamic motion.
