EXP

The "EXP-GPS2" extension is a user friendly GPS speedometer, combined with an Alti-Variometer. Speed is computed and given by reference to the ground, in 2 dimensions or in space, in 3D, by combining the altitude variation computed from the pressure sensor data.

Furthermore, it gives altitude above the sea level, the heading, as well as the number of visible satellites, and GPS position to relocate your model in case of loss (by using a smart phone).

The EXP-GPS2 external power supply can be measured and displayed on the Cockpit, using standard under-voltage alarms. This connection is equipped with “zero standby power”, which means that it draws no current when the IISI-Link is inactive. You can keep the battery connection without discharging it when your model is not used. Without this power supply, the GPS2 works as standard vario / altimeter based on air pressure.
