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 lt5 minute Direct HP
