Notes on Array Mounting

Recommendations:​

1. We recommend maintaining 10 ft (3 m) between sensors in your array to avoid any “crossing” of tracks due to GPS error. ​
2. The turfRad GPS accuracy is approximately 1.5 m (5 ft) per sensor.​
3. Crossing of tracks will throw off the moisture interpolation algorithm taking the wrong side’s measurements for interpolation with the next pass which can cause “striping” in the resulting maps.​
4. Arrays with 2 sensors are more manageable, 3 sensors will require roughly 10 ft booms on each side of the cart. ​
5. There is no limit to how fast you can drive. The sensor takes 10 measurements per second. The table below shows the measurement spacing, in the driving direction, according to driving speed:​
   
   

6. Important: Make sure your GPS antenna is mounted as close to the sensor as possible.
