Calculating a coordinate?

Is there an online calculator somewhere that will take a known
coordinate and give you a second coordinate based on distance and
bearing from the known coordinate. It seems like this would be easy to
find but I haven't found one yet. My GPS receiver will do this but only
takes distance input to one decimal place of a mile. I need more
accuracy than that.

TIA

Yeah, the USGS has a survey quality geodetic forward...

But the direction of a Geodetic forward is just the initial direction to the
point...

...while the direction of a UTM forward would be the direction all the way
to the point. And that might be more logical to many people...

So, convert the latitude and longitude to UTM North and East coordinates and
call them N1 and E1.

Now calculate both a geodetic inverse and a UTM grid inverse between N1,E1
and N1 +1000, E1 . Note the difference between the geodetic inverse and the
UTM grid inverse and apply that difference to the proposed forward direction
to match the UTM grid orientation.

Next, take the Cosine of the adjusted direction, multiply by the distance,
and net with the N1 coordinate to arrive at the forward North coordinate.
Take the Sine of the adjusted direction, multiply by the distance, and net
with the E1coordinate to arrive at the forward East coordinate. Now convert
the forward UTM coordinates to latitude and longitude...

Best thing probably for you to do this is the free Windows program FWD/INV
