  2. Satellite receives


Among the most powerful and compact surveying instruments, the one used by Axist’s specialists is GNSS, which is frequently used for surveying, tracing and surveying/mapping, ensuring centimetric precisions. Complete with master, references and connection to the national network of permanent GNSS (global navigation satellite system) stations.

Leica GS14

In particular, the model of the Leica GS14 satellite receiver, consisting of a compact and powerful smart GNSS antenna, is suitable for any measurement activity and is equipped with integrated mobile communication devices and UHF modems. With its practical and integrated design, the Leica Viva GS14 is an easy and intuitive tool to use.
