Progress in the Development of Laser Strapdown Airborne Gravimeter in China

Based on laser gyros and quartz flexure accelerometers, Beijing Institute of Aerospace Control Devices has developed the prototype of Laser Strapdown Airborne Gravimeter (LSAG). The hardware improvements and the design of post-processing software are presented, and field test results of the system on the aircraft and oceanic vessel during 2013 and 2014 are given. Field test results showed that the internal accord accuracy after level adjustment was about 1mGal, demonstrating that LSAG has the abilities to implement airborne gravity surveys, and has the potential for marine gravity surveys.
