Consumer product global positioning system (GPS) receivers use inexpensive clocks that introduce a significant error in the location process. While only three satellites are adequate for high quality, synchronized clocks, four or more satellites are typically necessary for reasonable accuracy when inexpensive, low quality, unsychronized clocks are in the receiver. We present an inexpensive, fast algorithm to improve the location procedure for consumer level products with low quality, unsynchronized clocks.
