GPSS Converter

Call 1-800-447-3408 for Ordering and Installation Pricing.

GPSS integrates the autopilot with a GPS navigator function which outputs roll steering commands. GPSS does not follow a CDI needle movement; it flies direct right/left steering commands from the GPS for extremely accurate, hands off GPS navigation.

In GPSS mode the autopilot will accept the steering commands from the GPS unit without any further input from the pilot. While in GPSS mode, the autopilot annunciates NAV GPSS. GPSS will not function unless a valid 429 digital roll steering signal is available. Lack of a solid signal causes the GPSS annunciator to flash.The GPSS Converter upgrades any existing S-Tec autopilot to include the GPSS function.

The GPSS converter is configured in three different physical packages: Horizontal panel mount, case contained; Vertical panel mount, case contained; and Remote mount control box with panel mounted switch.

The lighted panel switch selects GPSS or Heading mode. Note that if a valid roll steering command is not available, GPSS will not activate and this will be indicated by a flashing GPSS light.
