GPR Roteg. discover the unseen
Roteg is very powerful, state-of-the-art GPR developed by RTGPR company. Technical parameters rank it among the world leaders for detecting and location of underground objects. Roteg’s effectiveness has been tested, as you can see on our radargrams.
The device consists of several main components: receiver, transmitter, antennas and PC with the program. The basic component of supplied GPR Roteg system is receiver and PC Ruggon with our program Spirio to control GPR. Our receiver is delivered with Vniismi (Loza) transmitter, but it is also compatible with other transmitters. Its unmatched input and output design allows to use antennas with wide frequency range from 0.1 to 1000 MHz, which enable you to search for archeological objects and explore the soil to the depths of hundreds meters. The whole system is modular and can be installed and combined with other components. The system is fully compatible with GPR Loza components.
We have been very hard working for 5 years on the inhouse development of our unique receiver in particular. Our receiver is able to process high voltage antenna outputs. Thanks these abilities we can use special designed autonomous pulse generator transmitters which are capable of giving a voltage pulses up to 30 kV. The system of non-degraded, continuous, full-length signal recording is particularly suitable for archeology as well as for geology – up to hundreds of meters underground. The receiver is not galvanically connected to the transmitter – it is wireless synchronized. Therefore it can cooperate with a number of different transmitters.
The selection of antennas frequency and thus the resolution and depth should be always realized with respect to the anticipated object. The importance of right antenna selection is also related to the survey economy. Underground survey can be done very fast with indicative results but also with detailed mapping of the found anomalies. GPR uses a set of unscreened broadband antennas for different depth ranges and resolution which vary from short antennas (30 cm, 500 MHz) to the long antennas (15 m, 10 MHz). We can supply the antennas with an impedance range 1-50 Ω, for use according to the characteristics of the measured subsoil.
The output data files (DAT, PAR, COR and TOP) can be opened in ReflexW software. The data format can be adapted to meet your requirements. Data can be also exported to the Krot software.
For our GPR, we chose an industrial PC Ruggon, which according to our experience is fully convenient for hard conditions of GPR surveying because it is waterproof (IP65), has a long battery life and it is equipped with a high brightness display.
Taiwan-based RuggON Corporation was established in 2014 as a provider of ruggedized computing products. Versatile rugged 10.4-inch tablet computer Ruggon PM-522 uses an Intel Atom E3827, carries IP65 sealing, offers 4G LTE, two cameras, a 2 MP front-facing cam conferencing, and a rear-facing 5 MP camera documentation and much more.
The 700-nits sunlight-readable screen benefits from anti-reflective coatings and circular polarizers. In terms of size and weight, the PM-522 – designed for a wide range of field mobility duties – measures 10.8 x 8 inches and is just over an inch thick. Weight is 1.3 kg (without the protective rubber bumpers). In-box Accessories: stylus, hand strap, shoulder strap, Ethernet adapter, power adapter.
Delivered transmitter belongs among the most powerful transmitters in the world. It is able to provide very fast and stable high-voltage pulses from 5 kV to 30 kV (depends on type), making possible to get to much greater depths than conventional GPR.
Pulse freguency is around 900 Hz, pulse length is 3-5 ns. The transmitter is powered by its own internal batteries.
