Description

The model G-823A Cesium Magnetometer provides unmatched versatility of performance, size, function, and cost-effectiveness for larger scale aerial-based magnetic surveys. It can also be used as land portable system.

In addition to the magnetometer measurement, the internal CM-201 counter also includes Julian time/date, a provision to accept an external sync pulse, and six A/D converters for digitizing and recording signal amplitude, radar/barometric altimeter, EM or other analog data. The transmission format of all functions is selected by software command and may be customized for each job.

The G-823A meets the highest vibration and temperature standards for airborne, land, or marine surveys. Custom-length cables and special packaging are available for each of these applications. Critical heading error performance is documented and supplied for each G-823A system.

Geometrics offers a complete system including magnetometer, GPS navigation, data logging and display software, post-acquisition data processing software, and training. Expand your Magnetometry surveying capabilities with the versatile multi-sensor array capable G-823A Cesium Magnetometer!

TYPICAL USES

  • In-Accessible Terrain: Difficult or dangerous terrain is no longer a problem, making it perfect for surveying wetlands, heavily vegetated areas, extreme terrain, or protected lands.
  • Environmental: Find abandoned wells, pipes, and storage tanks quickly and with precise positioning.
  • Archaeology: Survey vast distances and leave potential archaeology sites undisturbed from the air.
  • Geology: Survey for regional variations in the magnetic field.
  • UXO Detection: Collect data at high speed with a fast sample rate, making detection and delineation of UXO quick and easy.
