UCT,UDH,CAL: Calculate Local Geoidal Surface

$PASHS,UCT,UDH,CAL
This command computes the estimated parameters for local geoidal surface. In
order to compute the estimated grid transformation parameters, you must have
entered the four data points with the $PASHS,UCT,UDH,APT command.
$PASHQ,UCT,UDH,CAL
This command queries for the estimated parameters of the local geoidal surface.
$PASHQ,UCT,UDH,CAL
The response is in the format
Table 6.62 outlines the parameters.
