MinGeo Automatic D/I Theodolite Digital Station (ADS) instrument

ADS stands for Mingeo's Automatic Digital Station instrument. It is an automatic declination/inclination (D/I) theodolite system, aimed to replace the manual observatory D/I measurements. ADS can be integrated with the standard geomagnetic observatory instruments (variometer and scalar magnetometer), to realize a complete observatory system. As ADS can work automatically and it can be checked remotely, so the number of visits in the observatory can be considerably reduced.

ADS' main part is a Zeiss theodolite converted to steel free and equipped with non-magnetic piezo motors, digital angle readers and digital camera, to allow autonomous operation. The controlling electronics is in a separated box. This basic ADS system allows self-operation and remote check through the Internet.
