Thank you for your purchase!   This instruction manual will guide you through the installation and operation of your GPS 
V4.   Please read the entire manual carefully before proceeding.    If, after you read the manual, you have further 

questions or problems, see the Support page on 

http://www.eagletreesystems.com

 for additional information, or email us at

Intended Uses 

The GPS Expander V4 

(the GPS) 

is intended for use exclusively in model planes, boats and cars.  Other uses are not supported.     

 

Features 

The GPS is designed to be used with all present Eagle Tree recording, OSD and wireless telemetry products.   The GPS updates at 10Hz, consumes 
very little power, and has battery backup for quick hot and warm starts.     
 
Our Data Recorder software includes support for Google Earth, including live mode display, and Google Earth Track support for logged data.  
 
The GPS includes onboard filtering, as well as a toroid ring filter, to improve signal reception, especially when used in conjunction with First Person 
View video transmitters. 
 
The GPS’s built-in LED indicates when a 3D fix has been attained, for convenient usage.   The LED flashes UNTIL a 3D fix is attained, then stops 
flashing.   
 
The GPS is tiny and lightweight, making it perfect where weight and size are issues.    See the Specifications section below for more information.    
With our Windows software, and now with Google Earth™ software, your GPS data can be easily and fully visualized. 

 
Supported Products 

The GPS is compatible with the Eagle Tree Systems eLogger V3, Flight Data Recorder V2, Car Data Recorders and Boat Data Recorders with 
firmware version 5.55 or higher
.   It is also fully compatible with Seagull Dashboards with firmware version 4.76 or higher.    If you have 
firmware lower than this version, go to our support website, and download the latest software, which will update the firmware of your device.    
 

Packing List 

Your package should include the following:  the GPS, and a printed version of this manual.   Please check your packaging for printed addenda to this 
manual which may be included if changes were made after printing. 

 
How the GPS Works 

When coupled The GPS uses satellite information to determine position, speed, altitude, course, 
distance to operator, and UTC time.      

 

Connecting the GPS to the Recorder 

The 4 wire connector attached to the GPS plugs into the rightmost port of your Data Recorder as 
shown in Figure 1.   Make sure that you connect it in the correct location on the recorder, and with the 
correct polarity!     
 

Connecting the GPS to the eLogger V3 

The 4 wire connector attached to the GPS plugs into the eLogger V3 as shown in Figure 2.   Make 
sure that you connect it in the correct location on the recorder, and with the correct polarity!     
Note: The GPS draws significant current from the eLogger.  When the eLogger is powered by a higher voltage pack, such as an 8s or larger 
pack, or a pack above 30 volts, the eLogger’s regulator may shut off after a short period when 
used with the GPS.
   Please use our “Battery Backup Harness”, part number CAB-BAT-BACK, or 
build your own, to provide supplemental power to the eLogger if you encounter this issue. 
 

Installing the GPS in your Model 

The GPS should be mounted with Velcro in your vehicle so that the top part (with the label) is facing 
toward the sky.   Normally, it is satisfactory to have the GPS inside the vehicle, since the skin of most 
vehicles is relatively thin.   If you have difficulty getting a signal, try mounting it externally to the 
vehicle.
