It takes a position between the low-accuracy, low-cost MEMS gyroscope and the higher-accuracy and higher-cost fiber optic gyroscope. Accuracy parameters are increased by using low-intrinsic damping materials, resonator vacuumization, and digital electronics to reduce temperature dependent drift and instability of control signals.<ref>{{cite journal |url=http://md1.csa.com/partners/viewrecord.php?requester=gs&collection=TRD&recid=A0017841AH&q=coriolis+vibratory+gyroscope+CVG&uid=789572486&setcookie=yes |title=Micromechanical inertial sensor development at Draper Laboratory with recent test results |journal=Symposium Gyro Technology Proceedings |date=14–15 September 1999 |author1=Ash, M E |author2=Trainor, C V |author3=Elliott, R D |author4=Borenstein, J T |author5=Kourepenis, A S |author6=Ward, P A |author7=Weinberg, M S |url-status=dead |archive-url=https://web.archive.org/web/20120823133655/https://md1.csa.com/partners/viewrecord.php?requester=gs&collection=TRD&recid=A0017841AH&q=coriolis+vibratory+gyroscope+CVG&uid=789572486&setcookie=yes |archive-date=23 August 2012}}</ref>
