I just got my neo 1973 by mail today and I will try to flash the image and load rootfs sometime in the evening. Just had a couple of questions as i am new here. <br><br>1. Is there a place where the latest tested image and rootfs is available for download. the wiki links to a number of files and one is not sure which image matches the rootfs.
<br>2. When I have connected the usb cable to a powered usb port and the neo is switched off is it charging (there is no indicator)<br><br>thanks <br><br>Rakshat<br><br>PS i am going through the wiki but if there is a forum where these questions have already been answered please guide me there so i don't mail the entire list every time.

<br>each satellite.<br>This does not directly give you a position. Some significant<br>spherical trig is necessary to turn this into position.<br><br>A lot of (AGPS) phones only have that hardware and rely on some system software
<br>(maybe not even on the phone) to turn that into a location. It makes<br>a lot of sense that if you<br>have a powerful CPU you don;t need to add another powerful CPU to<br>turn this GPS<br>base band info into PVT (position velocity and time).
<br><br>The second issue with GPS is that if you are going to take raw data<br>and generate PVT then<br>you have to do the GPS limitations that keep the system from being a<br>ballistic missile guidance<br>system IE you cant report position if altitude > 60K ft and
<br>velocity > 1000 knots or some such.<br>So if you plan to sell such hardware in the US then unless it has<br>these limits encoded<br>in a way that is not trivial to defeat it become a ITAR controlled munition.<br><br>
It sounds like the origional GTA01 used a standard phone AGPS that<br>does not directly calculate position,<br>a great technical solution, but it does not work in real partical US<br>political world with the ITAR<br>GPS restrictions.
<br><br>for details on what it takes to calculate position from the raw data see:<br><a href="http://home-2.worldonline.nl/~samsvl/software.htm">http://home-2.worldonline.nl/~samsvl/software.htm</a><br><br><br><br><br><br>
