GPS Coordinate transformations

[Cooper, Ben]

The DTCC software is also supplied as C source code with the executable -
NIMA really is very generous!  I haven't spent a lot of time looking at the
code, as there is quite a lot of it.  However, it does seem well structured,
so I'm sure you would be able to call the algorithms from within your own
code.  I could not find any copyright or usage restrictions applied to the
software.  I agree, though, that this would be quite a bit of work - someone
out there must have some ready made WGS84 to OSGB transformation code.

By the way, the Garmin GPS 12 will output data in any of its supported
grids, and OSGB is one of them.

Thanks Ben,

I am actually working with some GPS modules which have no supporting
software, so I need to code that up, and need the transformations as some
form of algorithm. The modules themselves only output in Lat, Lon & Height.
