Separating trends from noise in geodetic time series — with rigour.
- Trajectory estimation, with geophysical rigour.
Time series, noise models and trends, serving every decision.
Hector is a geophysical time series analysis platform.
Developed and maintained by the TeroMovigo team, Hector is today applied in geophysical research in Australia, China, Poland, Portugal, Romania, and the United States. It combines trend estimation and noise modelling in a single process, taking into account temporally correlated noise and providing realistic uncertainty estimates.
Trajectory estimation
Hector estimates linear trends with annual, semi-annual and other configurable periods, and allows for the estimation of offsets at specific epochs. The maximum likelihood estimation method simultaneously determines the trend and the noise model parameters.

More rigour. Less uncertainty. Better estimates.
Features
Trends that withstand the noise
Temporally correlated noise significantly impacts the accuracy of trend estimates. Hector estimates trend and noise simultaneously, ensuring reliable and defensible uncertainty estimates.
Robust analysis with incomplete time series
Geophysical time series are rarely complete. Hector eliminates the need for interpolation and zero-filling, handling missing data without compromising the estimation process.
Data quality control
Hector includes dedicated tools for identifying and removing outliers, generating power spectral density plots and automatically detecting offsets in the data.

When noise distorts the trend: the problem Hector solves
Temporally correlated noise significantly impacts the accuracy of trend estimates, making it difficult to distinguish signal from noise. Hector estimates trends and noise simultaneously, separating the real signal from fluctuations that can mimic it.
Incomplete series, intact estimates: how Hector handles what is missing
Geophysical time series are rarely complete. Hector handles missing data without interpolation or zero-filling, avoiding shortcuts and preserving the integrity of the estimation process.
