Hi guys!
1. I have a question about the accuracy of system from different brands. John deere and Trimble offers +-2 cm with RTK. So actually it is 4 cm. This is the signal and theoretical. Is there any other brand that offers better accuracy?
2. And what about the real life? None of the brands provide any information about the gyroscope/inclination sensor resolution? That is also very important, no?
An +-0.1 degree error resulting already almost 1 cm error at the ground (if the antenna is at 280 cm high). And if the system has only 0.2-0.5 degree resolution, then it results a huge error at the ground. It would nice to know this data also. Does anyone have any information about it?
Thanks,
Szotyi
I'm not aware of any manufacturers claiming better than sub-inch (2.5cm) accuracy at 8mi (13km).
To my knowledge, all manufacturers quote accuracy at the antenna, because that is the only accuracy that the manufacturer can control. There are too many variables between the antenna and the ground to be able to reliably quote on-the-ground performance. I'm not sure many people could tell the difference between 1.5cm and 2.5cm accuracy on the ground in actual operating conditions (vs controlled testing on a parking lot or driveway). |
