SmartQuantumMag - the World's most advanced and portable cesium (Cs) optical pumped magnetometer base station with sample rate up to 100 Hz. The complete ready to use set with accessories and battery fits in a carry-on size case and weighs only 8.5 kg. SmartQuantumMag can also be used as a part of a multi-sensor gradiometer, or even as a GNSS base and rover with centimeter accuracy in PPK mode. It is fully compatible with QuantumMag‘s console and can be applied for any type of ground magnetic surveys.

Easy-to-use console
The console enables easy configuration of operating modes, visual control of measured values and viewing of stored data from the built-in microSD card. Downloading data is performed via USB to a PC or smartphone. It is also possible to broadcast data via RS-232 or CAN ports in real time mode. The console is equipped with an OLED display (-40 ÷ +60 °C), built-in multi-band GNSS receiver with RAW GNSS data collection, and backlit keypad.

Magnetometer parts
The magnetometer package contains on the one hand a minimum number of unified parts to ease assembly and use, and on the other hand all the necessary components, so that you do not have to buy additional cables, a battery, or GNSS receiver without which you will not be able to work. Every magnetometer we ship is ready to use in its basic configuration. Options add functionality, but are not required by most users for standard operating scenarios.

Power supply
SmartQuantumMag operates over 9.5 hours of continuous measurements at -30°C from the battery included. At 20°C, the operating time increases to 16 hours. Continuous power supply in long term monitoring mode can be provided with a car battery, an optional low-noise power converter from 110/220VAC to 12VDC, or a solar panel.

Included LiFePo4 battery has the full temperature range from -40 up to +60°C and MSDS certificate for any kind of transportation.

SmartQuantumMag has no built-in batteries, which could complicate air transportation and sooner or later fail and require complex replacement.

Data format
User can create project folders that can be used to divide survey sites or data collection days. All measurements are saved in a TXT file in the project folder. The file from each magnetometer has a name containing the serial number of the console, the code of the measurement mode and the number of connected sensors. The files have a homogeneous structure, i.e. each measurement in the file is a line that contains all necessary information: UTC date and time, time zone, base name, measured field, estimated error, sensor serial number, latitude and longitude in decimal degrees, altitude, UTM coordinates with automatic zone and hemisphere selection, horizontal and vertical accuracy.

Even if there are many operators working on a survey site at the same time, you will always be able to identify which instrument was used for each single measurement in the database.

Multi-sensor gradiometer
SmartQuantumMag supports the ability to link through a CAN FD interface to create a synchronized distributed network of magnetometers. This unique feature allows flexible creating of multi-sensor gradiometer with the necessary measurement base. You can connect up to 6 SmartQuantumMag’s to the a MaxiMag console or build a multi-sensor gradiometer with an almost unlimited number of sensors using CAN-Ethernet interface unit.

Metrology and noise protection - a guarantee of high accuracy
Every SmartQuantumMag is metrologically tested. We control the standard deviation of random error (noise), absolute accuracy and orientation error.

The robust algorithms allow to perform measurements at high level of industrial noise, in a city environment, or right under high-voltage powerlines.

Reliability and warranty
Our R&D specialists have extensive experience in performing geophysical surveys. We are well aware that such equipment must be reliable, and the service must be fast and convenient. We give 3 years warranty on all our magnetometers, and our technical support will promptly answer any of your questions. If you are still working with outdated magnetometers - take advantage of our trade-in offer and protect your projects from potential problems.

Built-in multi-band GNSS receiver with centimeter level accuracy
Time and coordinates are provided by the built-in multi-band GNSS receiver with PPK feature, which allows to achieve a centimeter level accuracy. SmartQuantumMag also has GNSS receiver mode and can be used as a GNSS base, rover or tracker without mag sensor connected during any geophysical applications. Stored RAW GNSS data could be easely converted to RINEX format.

SmartQuantumMag also supports NMEA-0183 protocol and can be connected to external navigation devices via RS-232.
