GNSS RECEIVER AND EXTERNAL STORAGE DEVICE SYSTEM AND GNSS DATA PROCESSING METHOD
First Claim
Patent Images
1. A method of operating a GNSS signal -processing system, for processing GNSS signals from multiple satellite sources received by a receiver including a digital signal processor (DSP) and a general purpose central processing unit (CPU), which method comprises the steps of:
- receiving raw analog GNSS ranging and timing signals;
downconverting the raw analog GNSS signals to digital signals with an AD converter;
correlating the digital signals with the digital signal processor (DSP);
closing code and carrier tracking loops with the CPU;
calculating a GNSS solution and communicating the GNSS solution with a user interface;
providing output signals representing the GNSS positioning solution on a universal serial bus (USB); and
storing said output signals on an external storage device.
