Applanix POS AV sends NMEA data
required by iX Flight to calculate
aircraft position and flight director

iX Flight (in iX Controller) calculates
when to take a picture (based on
NMEA/GSOF data received from
Applanix POS AV) and issues a
trigger.

POS AV
RS-232
• iX Flight (in iX Controller)
calculates Start of Line and
before reached, sends "Stab"
command to Applanix POS AV
(for transfer to SOMAG DSM 400
stabilizer).
• iX Flight (in iX Controller)
calculates End of Line and after
reached, sends "Man" command
to Applanix POS AV (for transfer
to SOMAG DSM 400 stabilizer).
