Networks and function
Privately Operated Networks

• provide a varity of data formats (RINEX,
  RTCM)
  
• use data from some national stations
• commercial profit
• future partnerships

Conclusions

• A number of GPS active control networks
  are being established
  
• Encouraging establishment of partnerships
  between governement, science and private
  sectors
  
• Provide positions in terms of one unified
  system - NZGD2000
