The Smart Port GPS (GPS V2) sensor is easy to use, just plug it into a Smart Port equipped receiver at one end, and position the sensor so the end marked "UP" has a clear view of the sky. This sensor does require an X series receiver. Early Taranis transmitter users may require a firmware update to take full advantage of this sensor.
Can report the following data to most devices: Altitude, position, speed, UTC time, etc. Taranis transmitter can data log this data for you.
Dimension: 40mm x 20mm x 9mm
Operational Voltage: 4 - 10 volts
Current Draw: 80mA @5V
Time to Fix: 30 seconds cold
Speed Accuracy: Aprox 0.1m/s
Position Accuracy: Approx 2.5m CEP
Limits: 4G/ 50,000 meters, 500 m/s
Smart Port ID#: 4 (can be changed with channel changer)
Compatibility: FrSky Smart Port enabled receivers such as the X8R, X6R, X4R, etc.
The unit works as expected, as far as it comes to log data. In this sense, I have to point out that I was not able to see in the google earth any maneuver, which seems that when the plane is not upside horizontal, the GPS skips data collection. Meaning, I was not able to see a loop, for example. However, if someone proved otherwise, I would like to know what I am doing wrong.
Anyhow, my worst disappointing, and I want to be clear that here is where wrong expectations come from, is that I was expecting an almost real time feedback about distance altitude and speed, so that I could use that information for flight control. It happens that the delay is about 5 seconds, and translated to traveled distance, it is too much for any airplane.
This is a fantastic sensor for logging ground speed, coordinates, and distance. The neatest thing is that you can pull up the values on a graph to compare flights. Also, you can pull up the coordinates on Google maps to see the flight path. I use this as an E-F1 pylon racing training tool. The only minor negative is that mine does not bind in 30 seconds as the stats state.
Works very well with my X6R, and X8R receiver. I get a full GPS fix in a few seconds. First start-up took only about 3 minutes until it had downloaded the GPS satellite almanac in my area (Nevada, USA). It's great for viewing your flights in 3D in Google earth via the Taranis data log.
Works Better than most previously used gps units I have tried with osd's over the last few years
