A GPS receiver that supports SBAS, etc will tell you where the sats are. Some only report to 1 degree, others 0.1 to 0.01 degrees resolution. The beam with of a small dish at GPS freqs is not all that narrow.
Using orbital elements or processing the GNSS ephemeris message will give you a result with quite a bit better resolution.
> There is another problem in that area. How accurately is the location of the
satellite known? published?
