Actual GPS positional accuracy depends mainly on other factors like sky view, satellite positions, their numbers, atmospheric and other interferences, etc etc. What antennas give you is better signal reception which means the GPS picks up weaker satellite signals, resulting in perhaps '"seeing" more satellites, therefore giving you the best possible accuracy. Secondly, no amount of antenna can in fact improve your positional accuracy substantially. What this cord extension allows you is to mount the GPS on top your vehicle for a better/unobstructed sky view so that you get a quicker fix, and perhaps slightly better positional accuracy.

I want to answer your question in two parts.First, what you are seeing here in pictures is not an antenna, It is the GPS itself, which comes with a ceramic patch antenna like many other GPS modules and receivers. Here is a picture of mine (with an OTG cable lying around). Mine is of latter type, I bought it from Amazon (UK) for about 30 GBP, it looks likes this. Generally they come in two shapes: in a USB stick like your flash memory stick and in a mouse-like appearance - GPS chip in a case connected to a long cable to USB port.

What if you don't have a USB GPS already, and may be planning to have one? Well, go for it. What if you have a USB GPS instead? I am going to share my experience here.Īssuming that you have a USB GPS which can spit NMEA sentences (most of them do, as I know of), you can connect it to your Laptop through a standard USB port and use an appropriate software to collect location and other information from the GPS, or start logging data in a file for later use. This realization makes me write this post. This may be because not a lot of stuff on the Internet with appropriate keywords is available on the subject. The very first post on this blog Using an external bluetooth GPS with Android device is creating quite a bit of traction for my blog lately.
