Traceability of the FG5X-220 to the SI unitsThe Micro-g LaCoste FG5 is a free-fall gravimeter with a laser interferometer in Mach-Zehnder configuration which uses simultaneous time and distance measurements to calculate the absolute value of g. The instrument itself contains the necessary standards, a rubidium oscillator and a He-Ne Laser, and operates independent of external references. These internal standards need regular comparisons.Led by: Dr.-Ing. Ludger TimmenTeam:Year: 2012© IfE / M. Schilling
