[OZAPRS] Something is wrong, this is a fixed location.

[Darryl Smith]

Not quite as good as the time I saw my car driving from Sydney to Newcastle in a few minutes. In that case it turned out that the Trimble GPS receiver could only hear a limited number of satellites (one?), and decided that it was locked on, and so the car followed at a fixed distance from the satellite from what I can work out.

Following that episode I got Trimble to issue a factory note that stated that their GPS receivers should be switched off in areas of no coverage

p.s. When I am actually flying, the GPS looks a lot more sedate. Aviation GPS units do a lot of self-checks for obvious reasons

The system is not as perfect as we imagine.

Occasionally - happily very rarely - things happen which are clearly not correct.

Have a look here<http://www.users.on.net/%7Etfneumann/Public/IMG_4035r.jpg>  at a photo I took about 6 months ago - pay special attention to the speed.

The photo was taken for the altitude reading.  I didn't even notice the speed until I downloaded the pic from the camera a few days later.

No, I wasn't flying - although I'm not prepared to concede that immediately when I get around to pin the picture to the gliding club notice board  =-O .

Nor was I on the motor bike; VStroms are fast, but not quite up to that.  Push bike? Nah - no way.

It was in our stationary Misterbishi Lancer (VK5ATN-9) in the car park at Dead Horse Gap on a return trip from Cranberry.   Curious indeed!
