Default Announcing GPS from Eagle Tree

Press Release – November, 2005

GPS Expander Module from Eagle Tree Systems, LLC

Eagle Tree Systems is excited to announce the availability of our micro GPS Expander Module for our Data Recorder and Seagull Dashboard Telemetry systems. The units are in stock now, and ready to ship.


With the GPS Expander Module, our Data Recorder and Seagull Wireless Telemetry systems become fully GPS enabled. Now you can log model position, visualize the model on a graph against a photo image of the field, and see the position of the model on the Seagull Dashboard screen or on a laptop via the Windows Virtual Dashboard software. No more losing planes in the weeds!


Here are just a few of the features enabled with the GPS Expander Module:
[ul]Pitot/Static Airspeed, barometric altitude, voltages, g-force, etc.[/ul]
[ul]Lat/Lon, GPS Speed, GPS Altitude, Course, Distance to Operator, and UTC timestamp[/ul]
[ul]Last known position displayed on Seagull Dashboard for easy location of a lost vehicle (with a separate handheld GPS to guide you to the location) [/ul]
[ul]2D and 3D position graphing in the Virtual Dashboard software, with support for overlaid images of the field [/ul]
[ul]GPS Altitude to 18KM [/ul]
[ul]GPS Speed to 515M/S [/ul]
[ul]Built-in Battery backup for fast position locating on restart [/ul]
[ul]Low power draw (approx. 33 mA) [/ul]
[ul]Tiny: dimensions approx 45mm x 50 mm x 10mm and weighs around 23 grams [/ul]
[ul]Position accuracy 7 meters CEP (90%) [/ul]
[ul]Logging of position throughout the flight[/ul]



Note: Previous Recorders and Seagull systems require an upgrade to use our new GPS Module.

What is the accuracy of your gps system when measuring speed in a dive from altitude?

Hi Bobber and Wojtek,

Sorry for delayed reply. The unit records/samples at 1HZ for the GPS params. Speed from a dive is best measured via the (included) pitot/static airspeed sensor, since GPS speed is most accurate with horizontal travel.
