Placing a Cache with Android in GPS technology and devices Posted July 25, 2011 If you use your GPS on android you should check out "GPS Status & Toolbox" in the market. It's free and works great. It displays your GPS and sensor data: position and signal strength of satellites, accuracy, speed, acceleration, and bearing. You can also reset your GPS and download A-GPS date for faster fixes. It shows where and how many satellites you're currently locked on to. Now that I’m looking at it more, I could prob use this to see my current location to place a cache. I think I'll use this and "GPS Averaging" to see if they differ at all for the same location. I'm gonna try to use the GPS Status & Toolbox to fix a location (leaving it there for 5mins) then come back the next few days and do the same... see how much it differs day to day. Yes it does tell you how many satellites you're locked on to. But did you happen to notice the display on the opposite side of the display? The one that says Error? It shows your coordinates are accurate up to 24 meters. That's a possible error of just over 78ft. A little more than what is considered acceptable when placing a cache. My handheld GPS regularly has a lock of at least 10 out of 12 satellites and an accuracy of 3 to 5 meters. That's a considerable difference between devices if you ask me. Don't get me wrong, I love my Android phone. I'm on my third one. When I'm caching it's always with me. It has all my cache info on it. But it stays in my pocket. As good as it is, it's no replacement for my dedicated handheld GPS. I think that image is a bad example, in full view of the sky my Desire HD usually gets down to about 2m error quite quickly. The number you get on there though is still going to be a little out, when looking for a cache I find I have to walk around the area in a circle as it says im 4m's away even when i have walked 5 m's in that direction For placing though I use the GPS averaging software you mentioned, then test by walking 30m's away then trying to go back to it. Many cache's I place have had comments that the Co-ords were spot on, so I'll stick with that. Buying a 3rd spare battery though, as a days caching is pushing it with 2 Yea, that most certainly a bad example of an android phone GPS specs. I just took a random image off of Google to show people the program. I’ve never seen mine anywhere near that many errors. It’s almost like the person posting the picture just did a screen shot of their phone wile they were in their house next to their computer. That’s the only way I can get that kind of errors… when I'm inside of an office building. I’ll download a screen capture program for my phone and post a picture of my GPS specs so people can see the difference between a good phone with GPS and a bad phone (or bad location example).
