<div>Nice test but I have a concern that only simulataneous test is a fair one (two FR side by side)</div>
<div>This is because gps satellites are constantly moving (2 orbits per day) so results can change</div>

<div>Therefore I don't think we can place too much weight on time difference above in case particular building configuration in your in-door test suddenly shaded one crucial satellite....</div>

<div>Overall, getting indoor gps fix at all is pretty impressive - SIRF III is great chipset.<br>If you bought GPS from 5 years ago this would be impossible for phone app.</div>
<div>Also my (last year) O2 XDA Orbit is will not get indoor gps lock....</div>
