Resolves an absolute position from a single surface CPR frame plus a
known nearby reference position, per DO-260B SS A.1.7.6. The reference
must be within roughly 45 NM of the true position - typically the
receiver's own location, since surface traffic is by definition close to
an airport the receiver can see.
