G-823  Airborne  Cesium Sensor and Internal CM-201 Counter Module

This  new G-823A model includes the well proven high performance  G-822A sensor with the small  size CM-201 Larmor counter. It provides unmatched versatility of performance, size,  function, and cost effectiveness.

In  addition to the magnetometer measurement, the 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 amplitude, radar / barometric altimeter, EM or other analog data.

Resources:

The  system's high performance and multifunction capability are excellent for  mapping geologic  structure, for mining, oil and gas exploration and the detection of buried drums for  environmental surveys. Custom cable lengths and special packaging are available for each  of these applications.

Once a new system has completed all phases of run-in and testing, reliability is very  high. The specialized Cesium components are stable and not subject to limited life or  early failure.  Even after years of operation, full conformance with original stringent  specifications can be expected.

Features:
  • Airborne and vehicle applications with multi-sensor array capability
  • High sensitivity
  • Versatility - CM-201 counter includes 6 channel 12 bit A/D converters for digitization  of altimeter or other analog signals, digital data stream concatenation
  • Superior resolution of the Cesium Larmor signal with the earth's field tracking rates  exceeding thousands of nT (Y) over 0.1 second periods
  • Gradiometer arrays offering simultaneous operation of up to six separate sensors using  the designed-in concatenation of the CM-201 internal mini-counter
  • Geometrics offers complete turnkey systems including Birds, Stringers, Wing tip  installation accessories as well as Digital Data Acquisition Systems, Flight Path  Recovery, GPS Navigation, Gamma Ray Spectrometers, VLF EM and Post Acquisition Data  Processing Software and training.

Configuration: Base Station G-823B

Producing sensors with extremely low heading error (+/- 0.25nT) is an expensive and  time consuming process. Some sensors are produced to a less exacting heading error  standard and are thus designated as model G-823B. These units are identical in all  performance and reliability  standards except for the heading error. Heading error specs  are not supplied with this model sensor. These systems are offered for base station use  (where heading error is not an issue) at a significantly lower price.
