Abstract:
The Harvest platform, located 10 km off the coast of California, has been an important verification site for altimetry reference missions for over 30 years. Due to the recent decommissioning of the platform, there
is now a void in what has been three decades of continuous data in that region. In anticipation of this decommissioning, a set of buoys with GNSS receivers was dispatched in the region to investigate the feasibility of replacing the tide gauge measurements from the Harvest platform with the GNSS-derived positions of the buoys.
We present results comparing one year of overlapping data between the Harvest tide gauges and the GNSS buoys. We consider the effects of wave models, attitude estimation, and multi-GNSS kinematic position estimation as methods for mitigating errors between the two devices.
