New Zealand is responsible for vast maritime areas that present a enormous economic opportunity, however, controlling our exclusive zone is currently infeasible without a high-level real-time view of on-the-water activity and sea conditions. The required data could be provided by a cluster of satellites, in the CubeSat format.

A current project funded by the National Science Challenge (SfTI) is developing the underlying science and technology needed to provide NZ with an overhead monitoring capability using space-based assets. New technology is being created to develop a synthetic aperture radar (SAR) sub-system for measuring surface elevation that is suitable for small/nano-satellite payloads. This will be combined with a lightweight array deployment system and intelligent embedded systems for optimizing the limited available power and transmission bandwidth in a small satellite.

The data we will obtain from our satellite system will help to monitor New Zealand’s exclusive economic zone (EEZ). Sea-level data will also inform climate models, which will help understand how the Earth’s changing climate will affect New Zealand’s primary industries and infrastructure in the long term.
