Is it the horizontal distance or is it the hypotenuse?</p>

<p> </p>
<p>In the above I have a Base at point A that is 10 meters away from the Rover at point B and it is also 10 meters higher. The receivers are precisely placed as indicated above.<br /> What distance is calculated by the GPS as the Baseline?</p>
<p>Thank you</p>
<p>Sincerely</p>

They have 4 models and each model has different frequency? </p><p>How about the controllers are they backward/forward compatible for example? Can I use any TSC2 controller with any rover/receivers?</p><p>Probably sounds like some stupid questions.
