NISAR is a deliberate response to a number of traditional radar monitoring issues, as a global baseline monitoring system  that makes ground movement data available to everyone.

NISAR combines L-band and S-band, so it can both penetrate vegetation and capture high-deta

The NASA–ISRO Synthetic Aperture Radar (NISAR)  satellite is a joint mission between the United States space agency NASA and the Indian Space Research Organisation (ISRO).

14 August 2025 – Auckland, New Zealand Avant Global Ltd has entered into an exclusive partnership with UK-based InSAR specialist SatSense to launch LandSure  – a New Zealand based monitoring and reporting platform for New Zealand’s residential and civil markets. The partnership between Avant and SatSense gives a continuous ten-year archive of ground-movement measurements collected by the European Space Agency’s Sentinel-1 satellites. These satellites operate C-band Synthetic

New Zealand straddles the volatile boundary between the Pacific and Australian plates. This tectonic marriage means our mountains, valleys and coastlines are always on the move – sometimes slowly, sometimes in sudden lurches. For decades, scientists relied on ground‑based instruments to measure these shifts. Today, we are using a combination of radar satellites and clever mathematics, to monitor the land movements... even from hundreds of kilometres above. InSAR land-movement

A satellite the size of a small car can spot the ground beneath it shift by less than the width of a fingernail. Interferometric Synthetic Aperture Radar (InSAR) does this by comparing the phase of microwave echoes recorded on repeat satellite passes; any change in path length shows up as coloured fringes that can be converted into millimetres of motion. Because radar works through cloud and in darkness, the technique delivers truly all-weather ground-deformation maps, turni
