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

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
