The GPS is accurate to ± 30 cm and has Coast technology, a Hemisphere GPS product which is particularly well suited for challenging GPS-satellite view applications. During temporary loss of differential signal corrections, sub-meter accuracy for up to 40 minutes or more can be achieved. The system provides outstanding performance in environments where maintaining a consistent differential link is difficult. The system provides accurate and minimal position drift.
The GPS antenna is mounted on top of the machine, more than 3 meters above the ground in a protective steel box and is isolated from vibration. This both protects the antenna and positions it in the highest possible location for optima. sky view. The system has been in operations since November, 2012 in a wide range of forest and weather conditions, in the far North without any GPS signal strength issues.
