The following procedures enable the
determination of a remote site location, using two separate tape sets: one recorded
at a control site (known position) and one recorded at a remote site (estimated
p o s i t i o n ) .
With data collected on tape from a sufficient number of acceptable
satellite passes (Table 4-4), the translocated position of the remote site will be
accurate to within 1 meter (3.28 ft) rms.
Translocated position is computed in the

NOTE
The first tape (usually from the remote site) is the one whose first pass
recorded occurred at a later time than first pass recorded on the second
tape.
