Observations Network Upgrade Project

The Observations Network Upgrade Project (ONUP) was developed in collaboration with Australian Aid and Geoscience Australia (GA) and is currently refurbishing and upgrading the measurement and communication technology at 12 South Pacific sea level stations.

The objective of ONUP is to maintain the existing capacity to measure, record and transmit high quality sea level data for a further 10 to 15 years. From 2010-2012, the project successfully upgraded sea level stations in Tonga, Fiji, Samoa, Cook Islands, Solomon Islands, Vanuatu, Palau, Micronesia, Marshall Islands, and Kiribati. In 2013, stations in Tuvalu and Nauru will be upgraded and the ONUP project completed.

In addition, the ONUP team commissioned a ‘test station’ at the Bureau of Meteorology’s Training Centre, allowing Bureau staff to fully field-test the operation of electronic systems and data communications equipment destined for use in the upgrade.

A fairly important development for Pacific islands mapping initiatives has occurred because of the results of the recently concluded European Space Agency GOCE (Gravity field and steady-state Ocean Circulation Explorer) mission.

The primary result of the GOCE mission is the “most accurate model of the geoid ever produced”. This new and improved data will eventually be incorporated into GPS software of the future and hopefully eliminate the need to devise complicated new national projections to arrive at “real” height readings for any point, when measured with current GPS equipment.
