Code 91, Display and/or Enter Residual Limit
Enter code 91 to display or enter the standard deviation of the 2D residuals limit
in meters. To change the limit, key in the new number and press the enter (E) key.
Satellite pass data whose 2D residual standard deviations are greater than this
limit will not be used in 3D position or translocation computations.
When the MX 1502 is first turned on, a limit of 0.25 meters (0.81 feet) is used. In
a noisy environment, the limit may be raised. When entering the navigate mode, the

range for the 150 channel is 23 to 42 kilohertz. This frequency is scaled to
correspond to the 400 channel display (code 54). A signal-to-noise ratio of 0
indicates no signal and 100 indicates a perfect signal.
Code 98, Display Passes in Memory
Enter code 98 to display the number of satellite passes for which data is currently
being held in memory for translocation processing.
