x.xx is the true heading in degrees
hh is a checksum
$PHTRO,x.xx,a,y.yy,b*hh<CR><LF>
where:
x.xx is the pitch in degrees
a is ‘M’ for bow up
a is ‘P’ for bow down
y.yy is the roll in degrees
b is ‘B’ for port down
b is ‘T’ for port up
$PHLIN,x.xxx,y.yyy,z.zzz*hh<CR><LF>
where:
x.xxx is the surge (X1) in meters (signed)
y.yyy is the sway (X2) in meters (signed)
z.zzz is the heave (X3) in meters (signed)
$PHSPD,x.xxx,y.yyy,z.zzz*hh<CR><LF>
where:
x.xxx is the X1 speed in m.s -1 (signed)
y.yyy is the X2 speed in m.s -1 (signed)
z.zzz is the X3 speed in m.s -1 (signed)
$PHCMP,llll.ll,a,xx.xx,b,N*hh<CR><LF>
where:
llll.ll is the latitude in degrees (two first l) and in minutes
(four last l)
a is ‘N’ for Northern hemisphere
a is ‘S’ for Southern hemisphere
xx.xx is the speed in knots
$PHINF,hhhhhhhh*hh<CR><LF>
where:
hhhhhhhh is the hexadecimal value of Octans status
