  21. HP Convergence

  22. OmniSTAR HP INITIALIZATION TIME • Convergence: 20 minutes average for 30 cm CEP • Improvement and implementation: • Use known point as start value: Within 2 minutes • DGPS as start value (50 cm direct, 10 Min for 30cm • Static Convergence: 15 Min • Re-initialization after • loss of signal <5 minute :Direct HP

  23. OmniSTAR 8300 HP Initialisation test

  24. HP Convergence over 80 hourly sample Estimated Standard deviation Real Standard deviation

  25. Convergence is dependant on Geometry

  26. HP Re-initialization How to go get back to HP accuracy in a tunnel or going under trees

  27. Challenging environments

  28. Re-Initialization • Static receiver • September 2003, Lafayette, USA • 69 gaps of 20 s (average)

  29. Re-Initialization, results Success rate: 98.5%, average error: 0.05 m

  30. Static re-initialization tests
