GPS at Tide Gauge Research
Tide Gauge Benchmark Monitoring - Pilot Project (TIGA-PP) is a pilot
study of the International GPS Service (IGS). The main objective of TIGA
is establishing a service to analyse GPS data from stations at or near
tide gauges on a continuous basis. The primary product of the service
is time series of coordinates of tide gauges and associated benchmarks.
This product will allow distinction between absolute and relative sea level
changes by accounting for the vertical movement of the station.
TIGAsA is a collaborative
project between HartRAO, NASA(JPL), the SA NAVY (Hydrographic Office) and
several other partners.
Within TIGA, TIGAsA will
function as a TIGA Associate Analysis Centre (TAAC), TIGA Data Centre (TDC)
and will install and maintain TIGA Observing Stations (TOS).
