Micro-g LaCoste Absolute Gravimeters

• Note 1: The FG5 accuracy is limited by systematic errors that in many cases cannot be determined indpendently and are in some cases based on theoretical estimates. Intercomparisons at TMGO indicate that different FG5s show 1.5 microGal agreement.
• The FG5 has an accuracy of 5 µGal if the ML-1 laser is used.
• Note 3: The precision specifications assume a quiet site such as TMGO.
• Note 4: FG5 and FG5L can be operated outdoors with a tent and generator.
• Note 5: Repeatability requires measurement on high quality measurement piers.
