I am very new to this side of the world. I am a classical embedded software developer. We want to incorporate GPS in our project. If I have the current Latitude, Longitude, Height,Heading (I hope this is what I think it is, the direction of the vehicle) and speed of the vehicle. Can I calculate the coordinates 20 meter before (I can also convert this to time scale). I am not sure how to proceed with this or what other information. I am not sure if this is totally possible at all.

In short, yes. If you know a location and a direction it is possible to calculate a different location 20 meters in front. How difficult that calculation is depends on what kind of libraries you have access to. This would be fairly trivial if you have some kind of GIS software available. If not, you'd have to dust off your trigonometry textbook I guess ;-) (because latitude and longitude are measured in degrees)

I assume your vehicle is moving in a straight line at a constant speed. If not, we don't have enough information. If so then have a look at this post. your question is not quite the same but it should give you some pointers.

@MappaGnosis, Yes considering the vehicle is moving in a straight line and at a constant speed. The thing is I do not have access for any libraries for doing this, everything has to be manually done.

@MappaGnosis, Thank you for that link. I went through most of them (haversine, Equirectangular approximation). The problem is I have 2 unknown variable (Lat2, Long2). That becomes impossible to find out with reverse engineering. In all of the methods given in that link, they are assuming they know 2 set of points and finding the distance between them. While I have to assume I know 1 set of point and distance between another and find the 2nd set.
