MagStation Magnetometer Base Station

The Geometrics MagStation is a self-contained cesium vapor magnetometer base station built for stationary monitoring of the Earth’s total magnetic field during ground, airborne, and marine geophysical survey campaigns. It records continuous time-series magnetic data at a fixed reference location — allowing post-processing software to remove diurnal field variations and solar storm interference from mobile survey data collected simultaneously by roving instruments.

The MagStation uses laser-pumped cesium vapor (Cs133) as its operating principle — a non-radioactive total field scalar magnetometer covering an operating range of 20,000 to 100,000 nT. MFAM sensor technology samples at 1,000Hz internally, with filtered and down-sampled output at selectable rates for different survey applications. Furthermore, the system weighs approximately 2kg and integrates GPS, onboard data storage, and a built-in wireless access point into a single compact housing — eliminating the separate GPS logger, data cable, and communications hardware required by older base station architectures. Magnetometer and GPS time values synchronize to within 1 millisecond for precise correlation with roving survey instruments.

The built-in GPS receiver operates at 50% CEP accuracy of 1.5 meters standard, improving to 1.0 meters with SBAS correction. Additionally, the MagStation can function as an RTK base station — broadcasting RTCM3 correction data via Bluetooth to compatible Geometrics MagSeries instruments to achieve centimeter-level rover positioning accuracy during high-resolution UXO and archaeological surveys. The MagNav Android app controls the unit wirelessly, displaying real-time magnetic field data and system status without the operator approaching and influencing the sensor. Standard delivery includes a carrying case, tripod, external battery cable, AC adapter, and Survey Manager software.

These systems serve Pakistan Army EOD UXO clearance survey operations in KPK and FATA, mineral exploration contractors in Balochistan and Gilgit-Baltistan, Survey of Pakistan aeromagnetic correction programs, oil and gas geological survey contractors in Sindh, and university geophysics research departments in Lahore and Karachi requiring GPS-synchronized diurnal correction data for extended field survey campaigns.

Tactical Supply Pakistan supplies the Geometrics MagStation for geophysical survey base station correction, UXO survey support, and mineral exploration procurement across Pakistan.
