NO JOKE ----- this is the reason we have Gravity A correct theory of gravity will show us these four (4) things: 1. It will show us why gravity also acts like acceleration (principle of equvalence). 2. It will show us the actual cause of gravity. 3. It will show us why gravitational mass and inertial mass are identical. 4. It will show us the speed of gravitational attraction.

Hi Everyone, My Sony GPS-CS1 has been misbehaving since Aug 19th. Since then it has been recording dates in April 2030. It looks as if it is adding 0x1c00 days to the dates that it is recording. Is anyone aware of some sort of roll-over in the GPS date format that could have triggered this? Is there anyone else with this device (or another device - I bet that

I tried sending a request to Garmin support through their website, but have...

Could anyone please help with a voice-sync problem we have?

Techniques to use both L1 and L2 are fundamental to high-grade GPS receivers, and I believe the patents related actually protect this small community to grow under the canopy of low-cost GPS receivers. I remembered many years ago I was told that the techniques could be roughly divided into 5 categories: 1. Completely codeless. 2. Squaring 3. code-aided squaring 4. cross-correlation (by...

Whist fiddling with my new E72 I came across a menu for changing the voices in the sat nav software. I picked one of the english ones more or less at random.

Anyone know which Garmin auto nav units have the option for 3 or more data fields stacked on the side of the map screen? I know the 1450 does this, and maybe the 1490? Others? Thanks!

I would like my software GPS receiver able to work 7 days or 30 days alone, without decoding the navigation message for ephemeris or downloading updates from internet or cellular tower, thus it needs an extended ephemeris solution in place.

Stephen Wolfram's book, "A New Kind of Science" gives us three (3) very important facts: 1. Mathematics can only explain simple things. 2. You need a model to explain complicated things. 3. But - a simple model can explain complicated things. It looks to me like we have a PHASE model here.

I've bemoaned in the past the problem with "widescreen" in-car satnav that the orientation in landscape format is the "wrong" orientation with portrait giving a better view of the road ahead.

I note that the Garmin 3790T offers both portrait and landscape format as well as other "interesting features'. The...
