I've been using a GPS Micro-Mini in SiRF binary mode. Sitting in one place and testing the GPS, I recieve XYZ locational data that have awful accuracy. Calculating the distance between measurement gives me a accuracy <50m and the chip is suppose to be accurate <3m. So I'm confused.
Is something wrong with the chip?
I'm fairly confident that I'm reading in the values correctly on my MSP430 UART so that shouldn't be the problem.
I've also read in NMEA data but I'm not sure how to calculate distance from longitude and lattitude. However the accuracy doesn't seem right either.
Thanks in advance for any help.
