The NZ Defence Force wants to put in ground terminals next year for its main military satellite system.

It has put out a tender to advise suppliers about 19 projects it is considering over the next year to 18 months.

These range from ground terminals for America's Wideband Global satellite network, to an infantry training facility, to an emergency management communications system for the Air Force in Auckland.

It noted the projects were not funded yet.

The US has been asking its partners to help pay to add two new satellites worth hundreds of millions each to the 10-strong network. It provides communication links between the Pentagon and combatant commanders, and NATO forces, among others.

New Zealand has put more than $100m into helping build the network since 2012.

A note about the ground terminals said they had been planned for the end of 2025, but this had shifted to next year.
