這邊有些新資訊關於PG-800
以下節錄自

老外也有在討論這棵 基本上應該是copy自DS-760 軟體部分都是相通
比較大的爭議是元件校正問題
老外認為DS-760在出廠時候 有對每一個Gyro做校正 而PG-800只是單純copy
而以下的大意是 如果在未校正的情況下 大約會有67%或者是更高的比例 會出現1度/秒的誤差
姑且不論道德問題 看看$$ PG-800應該還是值得買的吧:em14:
Unfortunately I'm not suprised by this. Recently I had access to some technical details of the spartan sensors and statistically only about 20% would have worked perfectly out of the factory without any calibration needed. More than 67% needed a calibration of 1 deg sec to make the run perfect.
Now if you take into account the heat that the gyro develops during use (no external temperature variation) and the fact that the pg800 doesn't come calibrated, you have a 67% chance (or higher) that it will drift at a rate of 1 deg/sec or more as soon as the gyro heats up internally... thats only a full piro in about 6 minutes in the best case scenario. Not good. |
