I've googled this lots and I'm seeing answers from 5M to 10mm accuracy quoted and thought I'd check if anyone here had any experience in this field.
What I want to know is, if I have 2 GPS units less than 100 meters apart and I compute the difference between their position, what accuracy can I expect. They will obviously both experience the same errors and so whilst their absolute position may have errors of many meters the differential position should be fairly accurate.
So, if anyone has two units they can connect to a PC, place them around half a meter apart and give me the two position strings from them, I would be very grateful. If you can also give me a bearing between the two that would be even better (actually marvelous). If anyone is able to do this then please let them sit there for 10 mins before recording the data.
Thanks,
Mike.
