Snowmobile/ATV/Boat-mode GPS guided

Ground-based snowmobile/ATV/boat-mode guided survey data are superior in quality and usefulness for inversion modeling compared to those acquired by drones or other aircraft because the sensor is much closer to the target mineralization. For example, a cesium magnetometer or other instrument is pulled behind a standard snowmobile.  The system can also be applied using an ATV or raft pulled behind a boat over lakes and rivers.  Specially designed carts are used behind ATV's for spring, summer and fall work.  Custom-built wooden, plastic and aluminum-frame sleighs are designed for rough terrain and conditions.  Please view the following power-point presentation on various modes: Snowmobile-Mode Surveys.pptx

Some Specifications:

  • Navigation track-lines pre-programmed, no existing grid is needed
  • Readings positionally or time triggered, typically 3-metre stations or 10 times per second
  • 'Ruggedized' navigation computer also records GPS and geophysical data - seamless
  • Survey speeds 2 m to 5 m per second in rough terrain - faster over fields and flat areas
  • GPS antenna located at front of sleigh or cart, magnetometer located at back of sled/cart
  • Post-processing includes Layback and Latency corrections
  • Operational in exceptionally rough terrain, boulder fields, etc. and in severe cold
  • Capable of collecting gradient magnetics data by adding sensors
  • Capable of adding other instruments (e.g., EM31, EM61, EM34, OhmMapper, etc.)


Base Station Magnetometer System:

  • Magnetometer readings at 0.5s or 1s intervals
  • At least 2 base stations running for quality control and duplication in case one fails
  • Base stations are 'leap-frogged' along the survey area to keep as close to survey area as possible - important for best precision in the arctic
  • Magnetometer readings linked to GPS time
  • All data are processed and plotted in the field using Geosoft and proprietary in-house software
