In this paper, the 10 channel NovAtel GPSCard receiver is presented. This receiver is available as a low cost, high performance GPS sensor, providing features and capabilities to support all OEM applications. NovAtel, a cellular systems and subscriber equipment manufacturer located in Calgary, has developed a completely new GPS receiver from the ground up. Incorporated within the design are advanced technologies at each major component stage, including: the antenna, the RF downconverter and LNA, the ASIC Signal Processor, the CPU, and the software configurable interfaces. This receiver has 10 dedicated channels and is capable of extremely accurate C/A code and Ll carrier phase tracking. The patented C/A code tracking scheme, which uses a wide bandwidth multiple bit sampling method (capable of P code accuracy), is described. NovAtel’s GPS sensor also has the ability to output both raw and final position data at rates suitable for even the most demanding applications.
