Survey Data Collection Systems

The SIR System-2000 Ground Penetrating Radar system is an easy to operate, portable instrument that can be run by a single person in the field.

Final results can provide information on the approximate depth and dimension of archeological features.

 SIR System-2000

All of GSSI's antennas can be used with the SIR-2000 system, enabling the user to focus on site-specific problems and adjust the depth of survey penetration and related feature resolution.

SIR 10B
The SIR System-10B is a versatile, multi-channel, digital GPR system.

A key feature of the SIR-10B is multiple antenna inputs. Two (2) antenna inputs are standard (4 optional) with the SIR-10B, which facilitates the use of various antenna geometry's such as monostatic, bistatic or multi-offset profiling, multiple parallel scans along a transect path, transillumination and tomographic studies.

Multiple channel capabilities can greatly reduce the time necessary to complete a survey. Additionally, the system has a 2.6 GB internal hard drive for reliable data storage.

Real-time data processing is possible in the SIR-10B and an optimal high quality thermal plotter provides real-time hard copy of field data. The system's flexibility makes it more suitable for a broader range of applications and it can run all GSSI antennas.

 

The SIR System-10H - This system features multiple data channels for greater coverage and survey wheel or DMI-controlled acquisition for accurate distance measurements.

Some features Ground Penetrating Radar can locate:
(All GPR survey results are site-specific and dependent on a number of factors, i.e., soil conductivity, dielectric permittivity, contrasting feature properties)
  • Modern Utilities (pipes, electrical wires)
  • Stratigraphy
  • Occupation surfaces if defined by particular soil-type, compaction
  • Graves
  • Pits, trenches
  • Walls
  • Voids
  • Metal Objects
  • Corrosion in structural materials
  
   
GEM-300 Electromagnetic Induction Profiler

The revolutionary design of the GEM-300 allows this frequency domain, electromagnetic profiling system to be configured to simultaneously measure up to 16 user-defined frequencies between 330 Hz and 20,000 Hz with fixed coil separation.

By acquiring multiple frequencies the user can select the frequency(ies) which provide the best results for a specific application. Both in-phase and quadrature measurements are recorded. Output is the mutual coupling ratio (Q) in parts/million (ppm) or apparent conductivity in mS/m.

All survey acquisition parameters and EM data are stored on internal memory. Files are structured for simple download to a PC for immediate presentation on commercial mapping software packages.

 Electromagnetic survey with the GEM-300
The GEM-300 is lighweight, portable and easty to use, which makes it ideal for many uses in the field of archeology.
