US Initiative Expands Appeal of Multi-GNSS Systems

A new US national space policy document unveiled recently by President Obama marks a major change of direction on the relationship between the country's GPS system and other GNSS systems around the world. And the change can only accelerate the development and interoperability of systems such as GLONASS, Compass and Galileo.

Whereas US policy as affirmed in a December 2004 national security directive was focused on maintaining the country's lead in GNSS on a unilateral basis, the new initiative reflects a more open attitude and calls for the USA to “engage with foreign GNSS providers to encourage compatibility and interoperability, promote transparency in civil service provision, and enable market access for US industry”. It also allows that “foreign positioning, navigation and timing services may be used to augment and strengthen the resiliency of GPS”.

The news will be a welcome shot in the arm for manufacturers that have already moved towards Multi-GNSS systems in advance of the provision of services. These manufacturers have been able to test their designs in advance of service provision using Spirent'sMulti-GNSS simulators, which are capable of simulating all published GNSS signals.
