*Note: this serviceable S-Tec GPSS Converter ST-901 comes with a yellow-tag.
The GPSS interfaces with the composite roll steering commands output by GPS navigators to fly a complete, pre-programmed flight plan—hands off. Its smooth waypoint transition calculates turn initiation point to fly from centerline of current leg to centerline of new leg, enabling autopilot to fly a precisely-curved transition path between legs. The reduced pilot workload eliminates need to set course arrow or heading bug at leg changes. Its enhanced autopilot functionality makes it fully-interoperable with any existing S-TEC model autopilot.
