NAMURU Software Defined GNSS Receiver
Overview
The "Navigational Apparatus Made at UNSW for Reconfiguration by Users" (NAMURU) is a software defined GPS receiver developed at the University of New South Wales, Asutralia, in coperation with General Dynamics, New Zealand. The name has ben chosen to resemble the Aboriginal word "ngamuru" for "following a path" or "navigating".The prototype design of the NAMURU baseband processor implements a 12 early, prompt and late correlator cannels for GPS C/A code signal. It is highly compatible with the Mitel/Zarlink GP2021 correlator that is also used in DLR's Phoenix GPS receiver . This enables a smooth migration of the Phoenix tracking and navigation software to the NIOS II processor of the NAMURU board and forms the basis for further research in the area of spaceborne GNSS navigation.
Planned applications and extensions of the NAMURU design at DLR include
- Tracking of new GNSS signals (L2C, Galileo)
- Fast signal acquisition under high dynamics
- Multi-antenna configurations
- GNSS reflectometry
