All the screen captures from my Nuvi. Here goes :
247km/h. Wooo.. That was sure fast. But satellite tracking was still good... I need to go faster...
Is this for real ?
At 500km/h, error rate is getting higher and I am losing a bit of satellite signals. More.. More !
898km/h ?!!!!
Something must be wrong here. How can I go so fast ? And normally, 2 satellite locks is insufficient to compute location information.
So where is this place that I can get to test my Nuvi at such high speeds ? Some secret research place ? Some place where the police are sleeping ? Well, no, cos this is where I was :
Actually, the max speed that was recorded was about 900+ km/h before all signals were lost.
So this GPS unit is definitely not used to guide missiles... Or maybe I just didn't stick my GPS near the window enough. (I wasn't seated at a window seat.)
Cos all these were taken when I was sitting near the window seat on my recent trip from Bangkok.
In Bangkok, where there are less buildings and more sky, I can get these good signals in a taxi :
