Geodetic equipment

The “Meridian+” owns a wide range of modern geodetic equipment including: digital tachymeters, dual-frequency geodetic GLONASS/GPS receivers, digital levels, line locators over 200 items total.

The “Meridian+” Enterprise constantly renews and supplements its geodetic equipment park to be always ready to perform projects of any complexity at the international standards level.

Currently the Enterprise possesses:

1. Laser Scanning Systems

Faro Focus 3D

The terrestrial laser scanner Faro Focus 3D

The Focus3D is a high-speed 3D laser scanner for detailed measurement and documentation. The Focus3D uses laser technology to produce incredibly detailed three-dimensional images of complex environments and geometries in only a few minutes.

Riegl LMS-Z420i

The terrestrial laser scanner system RIEGL LMS-Z420i - Riegl

The terrestrial laser scanner system RIEGL LMS-Z420i consists of a high performance long-range 3D scanner, the accompanying operating and processing software RiSCAN PRO, and a calibrated and accurately orientated and mounted high-resolution digital camera.

The system provides data which lends itself to automatic or semi-automatic processing of scan and image data to generate products such as textured triangulated surfaces or orthophotos with depth information.

2. Tachymeters

Digital tachometer Sokkia NET05X

This Sokkia’s NET series have been evolving in precision, functionality and versatility to meet the challenging needs of industrial precision management application. Featuring the latest technological breakthroughs, NET instruments offer unprecedented precision as well as the automated capability to satisfy the most demanding measurement tasks.

Digital tachometer Trimble M3 (5'')

Trimble M3 was developed for exploitation in complex, extreme environment. The model in a rugged case is highly protected against moisture. The M3 tachometer integrates Nikon optics and Trimble electronics. Full normal-mode operational day without recharge is up to 7 non-stop measurement hours. The digital tachometer M3 also operates in a reflectionless regime and provides significant distance measurement capability, to any object within the distance from 80 to 210 metres with a reflecting surface up to 90%. It allows an engineer to perform measurements by himself, thus saving time of other brigade members.

3. Geodetic GPS-receivers

GPS/GLONASS receiver Leica GX1230 GG-base

Leica GX1230+ GNSS is a three-system GNSS geodetic receiver with a multisystem antenna Leica AX1203+ GNSS with operating capability in RTK regime up to 40 km. Data is recorded on CompactFlash memory cards which allows cable-free field data downloading. A 2Gb CompactFlash memory card is supplied complete with the receiver.

Leica GX1230+ GNSS is a high-tech equipment designed in conformity with the requirements of a modern satellite equipment user. One of the requirements is operation in urban or forested areas, in conditions when satellite data acquisition can be critical. The LeicaSmartTrack technology allows the user to carry out operations in most complex environment: forest, city, open-pit mine, Far North. Main features of the technology: fast satellite acquisition and reliable tracking, even to low satellites in poor conditions.

GPS/GLONASS receiver Sokkia GSR2700 ISX

Geodetic dual-frequency GPS/GLONASS system produces high-precision imagery in real time and post-processing. The receiver integrated with a high-accuracy GPS antenna performs fast and high-quality survey, survey process management is exercised with the use of a field controller with SDR field programme or Bluetooth technology.

Sokkia GSR2700 ISX GPS receiver’s internal memory is sufficient for storage of a 500-hour survey, the screen is equipped with LED indicators, also it is important to notice voice message reports on survey process in 10 languages (including Russian).

NovAtel DL-V3

NovAtel's DL-V3 is a general purpose high-performance receiver designed for base station and rover applications. The DL-V3 incorporates NovAtel's OEMV-3 card housed in a rugged aluminum enclosure. The DL-V3 provides flexible connectivity through serial, USB, Ethernet and Bluetooth interfaces.

4. Digital levels

Trimble DiNi digital level

The Trimble DiNi digital level is a digital height measurement sensor designed for any job site where fast and accurate height determination is required, for applications such as precise levelling of flat and sloping surfaces, establishing the vertical component of grade and ground profiles, subsidence monitoring, and establishing the vertical component of control networks.

The Trimble DiNi digital level provides maximum output in day-to-day geodetic survey operations. It has a rugged structure (dust and moisture protection in conformity with the IP55 standard) which provides for its application in harsh field environment. Screen and circular level light allows operations in twilight.

5. Line locator
