GPS Setup Guide

Portable GPS’s

Many new handheld GPS’s have adequate output required to fly a TruTrak autopilot. Although most support data
output not all handhelds will provide consistent and reliable information required to fly all TruTrak autopilots. Therefore,
some handhelds will not fly the airplane well. Performance may decline by putting the processor in high-load situations.

We require a data output rate of once per second for best performance. Some handhelds output data at longer intervals
than once per second. These handhelds will cause the autopilot not to perform well in turns and it may cause overshooting and
hunting. If the baud rate is selectable the optimum setting is 4800. Most handhelds will require a data cable that plugs into the
handheld and provides a medium for data output. This is an accessory and is available from your GPS manufacturer. The
setup procedures are in your GPS manual. If your GPS is not listed here consult your GPS manual for NMEA output setup.
The autopilot must have a direct connection with the handheld GPS to provide the autopilot with RS-232. To allow the
handheld GPS to be removed easily you should add a connector in your panel. We recommend that you use a 9 pin D
subminature connector in your panel that will mate to the harness from the GPS. This will also allow you to wire power and
ground and use the aircraft electrical system to power your handheld GPS.
