Portable geodetic equipment "GEODESIA"
Portable multifunctional geodetic equipment "GEODESIA" is designed for high-precision geodetic surveys and combines:
- continuity and high accuracy of global GLONASS and GPS systems;
- advanced technology, compactness and high quality;
- large data processing capabilities, open architecture and reliability of the result processing programs.
Ease of use:
- compact and light-weight equipment;
- an original data compression algorithm, up to 8 MB of measurements in storage of the receiver;
- a whole day of work with a per-second recording;
- comes with a network adapter for the household electric grid;
The equipment provides an external event signal input and a timestamp output of 1 Hz.
The equipment is designed to maximize the effectiveness of static and dynamic surveys and can be used for a variety of purposes, such as:
- geodetic reference;
- grid creation and densification;
- building;
- land surveying work;
- engineering survey;
- topographic survey;
- land demarcation;
- land cadastre and much more.
