OpenStreetMap

New GPS device

Posted by Jeroen Muris on 9 January 2010 in English (English)

In the past few weeks I've been trying to collect tracks using my iPhone, but I found the results not very dependable - sometimes they seemed ok, sometimes they were way off. Yesterday I bought a real handheld GPS device, and the first results are promising.

It's absolutely unscientific, but my opinion is that the GPS in the iPhone is not good enough for OpenStreetMap mapping...

OSM is basically an incremental process of improving over time.

Something is always better than nothing, but do better if you can do better.

But yea, from what I've seen the GPS on iPhones is one of the worst out of any mobile phone with GPS, not sure if this is a chip issue or antenna or what but there is speculation/rumour that a lot of problems AT&T gets blamed for is badly designed iPhone antenna etc.

What I don't know is if the iPhone can use a bluetooth GPS device, these are usually cheaper than buying a stand alone device, but adds more bulk either way.

Most phones with inbuilt GPSs perform rather poorly because they have tiny GPS antennas.

As it's not primarily a GPS device, the engineers can't really justify the space a good GPS antenna would take up.
