A GNSS Phase Estimation Problem
A GNSS Phase Estimation Problem
Advantages:
  • Better multipath performance given same ROS
  • Programmable and increased linear region and gain for ɛ > 0
  • Same noise variance as EML kernel (w/ same ROS)
  • Discovered and compensated for GPS L1CA unbalanced transitions and non-transitions.
