10.2.3 Monitor Code Details — PCU
H Relative Az / Ship Heading position report. Reports simultaneous value of Antenna
Relative position and Ship Heading position in tenths of degrees.
Relative azimuth range is 0950 to 6250. Ship Heading range is 0000 3599.
PCU response: "RrrrrHaaaa", CR, LF, ">"
P Az/El/Cl Position. Response is one line of ASCII characters representing the antenna
elevation, true azimuth, and cross-level positions in tenths of a degree. Elevation range is
0000 to 0900. Azimuth range is 0000 to 3599.
