Scalable low-complexity GPS and DGPS positioning using approximate QR decomposition
GPS/DGPS with dynamically scalable on-demand positioning accuracy. QRD using CORDIC-based approximate rotations. Adjusting positioning accuracy by choosing the number of optimal CORDIC angles. The presented method is highly suited for hardware implementation. The presented method is particularly suited for recursive positioning.
