Hi Bjoern, as mentioned by someone else, most g-insensitive GPSDO products are probably going into military applications. But I could think of a number of commercial applications where a GPSDO is used in a vehicle and exposed to some tilt and lot's of vibration and vehicle acceleration. Also, if one needs ultra-low phase-noise, then a low-g OCXO will reduce any vibration/shock-induced error to show up on the output, as could be produced by a fan or other noise/vibration source. Satellite uplinks come to mind here. Or the house-cleaner running the vacuum cleaner through the lab... bye, Said In a message dated 7/11/2009 02:56:18 Pacific Daylight Time, b...@lysator.liu.se writes:
Hi Said, What GPSDO-products do compensate for tilt? It seem like a major error source -- if the user for some reason want to tilt a unit in holdover. It seems to be a "low hanging fruit" to attenuate this error substantially even with a $2 MEMS accelerometer. Once the ambitions grow -- more complexities can be added. Then again, is there a use-case giving some hope the engineering costs can be regained. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
