Measurement error
What is the
error on a TEC measurement? How does
it vary? What about the
models? Can we
reduce the measurement error by a precise rejection of
multipath?
• Physical models of the ionosphere (USU,
USA)
Use of the MIDAS images to improve the physical model and
to estimate the
errors
• Characterization of GPS multipath, Leading
an SBAS working group to quantify
and reduce
the errors on GPS measurements
