Graeme BlickOffice of the Surveyor-GeneralLand Information New ZealandFebruary 2003
Networks and function
• 30+ stations
• national control network
• monitor NZGD2000
• provides 30 second RINEX files
• future development?
Land Information New Zealand National GPS Zero Order Network
Existing PositioNZ Stations (12) plus Cape Roberts Antarctica
Planned by July 2003 (7)
Planned by July 2005 (10) plus 1 in Antarctica
30 sec RINEX files available through the Internet
Networks and function
Networks and function
• coordinated by GNS
• includes Otago University (Dunedin) and MIT
Deformation Monitoring Networks
Networks and function
Existing PositioNZ Stations - study of regional deformation partnership with LINZ
Tide gauge monitoring - 4
Specific monitoring networks
Networks and function
• 3rd party funded (EQC)
• developed by GNS
• 60+ stations
Dense Regional Networks for Monitoring Crustal Deformation
Networks and function
Monitor deformation along the North Island subduction zone
Networks and function
• provide a varity of data formats (RINEX, RTCM)
• use data from some national stations
• commercial profit
• future partnerships
Privately Operated Networks
Networks and function
8 stations - some in partnership
Example of a Privately Developed Network
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
