GPS Steering flies composite roll steering commands output by newer GPS units
GPSS interprets left/right commands and fly multiple waypoint courses and steering manuevers defined by waypoints automatically
Converts normal heading channel of autopilot to GPSS roll steering
Seperate panel-mounted switch and remote mounted control box
Lighted panel switch selects GPSS or Heading Mode and if valid roll steering command is not available GPSS will not activate which will be indicated by flashing GPSS LED
Compact size
NOTE: Only compatible with GPS receivers that have ARINC 429 outputs and Low Speed
Label 121 (bank angle command) and Low Speed Label 312 (ground speed)

PRODUCT FAQ
Click on a question below to see the answer. If you have a question about this model that is not answered below, please contact sales@seaerospace.com
What is GPSS?
In the past, general aviation autopilots have only flown flight paths by either tracking or coupling to Course Deviation Indicator (CDI) or HSI needle deflections. Due to deflection variations and noisy signals, the system might experience wandering. Tracking is simply the system reacting to signal input often providing very rigid flight turns and maneuvers for the autopilot. Roll steering commands are based on known location, flight path, speed, and anticipated turns & maneuvers. Therefore, autopilots enabled with GPS roll steering can fly the aircraft more precisely and smoothly.
What are some of the other benefits of GPS roll steering (GPSS)?
When an aircraft is equipped with a GPS system that outputs roll steering commands, a pilot can rely on the autopilot to control the steering of the aircraft for enroute or approach flight. Since the GPS determines the exact location and ultimate destination, the GPSS feature will fly the necessary flight path as defined by the flight plan in the GPS. At different legs in the flight plan, the GPS calculates the exact turn point based on the speed of the aircraft. The GPS then sends steering commands to the GPSS and the autopilot will fly a precisely curved transition path between the legs. GPSS greatly reduces workload by also allowing the pilot to not have to set the course arrow or heading bug at leg changes.
