The main differences are sample rates thus flying speed, heading error, dead zones and power consumption. See table for detailed explanation.

AeroQuantumMag
|
AeroSmartMag
|
|
Pros:
|
- High sensitivity (export license required)
- High sample rate
- Higher flying speed - 15 m/s
|
- No sensor orientation required, no dead zones
- Very low heading error, can be disregarded
- Lower power consumption - only two lightweight batteries are enough for a full day of operation
- Low and temperature-independent power consumption
- World’s lightest magnetometer - only 1.28 kg with battery and suspension system
- Does not require export permit
- Lower price - only 12,000 USD
|
|
Cons:
|
- Has dead zones – the sensor has to be oriented
- Higher heading error
- Higher power consumption, and is even higher in colder weather due to required heating of the sensor (normal for all optical pumped magnetometers)
- 200 grams heavier than AeroSmartMag
- Higher price
|
- Sensitivity is worse than that of AeroQuantumMag, but it is absolutely sufficient for most tasks and is on the same level as export versions of optical pumped magnetometers of other manufacturers
- Flight speed < 10 m/s - this is the speed our competitors fly with their magnetometers
- Sample rate up to 5 Hz = measurements every 2 m along the line, which should be enough, as lines spacing is 20-50m usually

Both magnetometers have advanced built-in GNSS receivers that allow centimeter accuracy in PPK of RAW GNSS data. This additionally requires either a separate GNSS base or our base magnetometer SmartMag or SmartQuantumMag.
