Baseband GPS Receiver Designed for Ultra-Rapid Position Fix

Baseband Technologies Inc., of Calgary, Alberta, Canada, recently announced the launch of its Deep-R technology, which the company says is capable of capturing a GPS position using two milliseconds of I/Q samples.

Baseband Technologies Inc., of Calgary, Alberta, Canada, recently announced the launch of its Deep-R technology, which the company says is capable of capturing a GPS position using two milliseconds of I/Q samples.

Baseband says the technology uses four patent-pending innovations that can operate in real time, post mission, and “push-to-fix” modes. Other features — such as no requirement for initial position, a low accuracy requirement for initial time error of up to tens of minutes and enhanced sensitivity for weak signal environments — are aimed at enabling manufacturers of wireless and unconnected devices to flexibly implement GPS functions in their products.  

“The problem with current GPS receiver technology is that it requires up to 60 seconds to obtain a first-position fix,” said Francis Yuen, chief executive officer of Baseband Technologies. “Not only can it rapidly drain the precious battery of a portable electronic device, it also makes unviable applications such as digital cameras that require almost instantaneous time-to-first-fix.”

The company says Deep-R is designed to provide a low-cost software-based solution for GPS positioning without the need for significant processing power and expensive hardware.  Instead of using a dedicated baseband processor, Deep-R employs a low-cost RFIC to extract, down-convert, and demodulate GPS signals.  Processing is performed in software using a general-purpose processor such as a microprocessor or a digital signal processor.  

Founded in 2005, Baseband Technologies focuses on advanced GPS research and development of low cost software-based GPS receivers that can be used for consumer electronics.
