Satsim City.
Researchers at DSTO Salisbury are developing measures to ensure the reliability of GPS within Australian Defence Force (ADF) military operations. One of the key tasks is to evaluate the shortfalls in current GPS equipment and identify future GPS requirements. To facilitate this, the group is building a navigation satellite simulation (Satsim) facility, at the core of which is one of the world's most sophisticated satellite simulators worth more than $2 million. The simulator allows accurate replication of signals from the entire GPS constellation, as GPS receivers would see them subjected to a variety of dynamic, environmental and jamming conditions. The simulator will be a central part of evaluating the requirements for GPS upgrades within the ADF over the next few years.
The Navigation System group is also helping to evaluate emerging technologies for military GPS systems through a series of live jamming trials at Woomera, South Australia. Woomera provides a large uninhabited area that is ideal for such trials since the jamming of GPS equipment in such a remote location does not have an impact on civil users of GPS. As a result, the Woomera test field is becoming attractive to the UK and US military, who find it increasingly difficult to conduct such trials in their own countries without affecting civil users.
Australia, the UK and US are finalising a trilateral memorandum of understanding, which will allow multi-nation collaboration on GPS research and trials in the future. The first joint GPS trial between the US and Australia, under a separate bilateral agreement, was held at Woomera over a 10 day period in March this year.
The trial tested one of the new technologies emerging from the US: the Jammer Locater (JLOC) system developed by the US-based Navsys Corporation. The aim was to evaluate its usefulness in reducing the vulnerability of GPS receivers to interference. Success of the trial has led to an agreement between Australia and the US to continue collaborative work and share information over the coming decade.
