  • Part 2 ~ GNSS constellations, and the errors which reduce positioning accuracy (9.4 MB)
  • Part 3 ~ Built-in methods to improve accuracy (code vs. phase-based operation, dual-frequency operation); augmentation (network-based differential, PPP orbit and clock corrections); use of multiple constellations (38.8 MB)
  • Part 4 ~ Fugro's SeastarTM services (19.2 MB)
  • Part 5 ~ Robust, redundant and reliable signal delivery (7.2 MB)
  • Part 6 ~ The remaining biases (multipath, signal blocking, system and receiver noise) (38.3 MB)
