Unmanned aircraft conducting a specialist survey over remote terrain

Geophysical data acquisition

Magnetic coverage shaped around the geology.

Low-level magnetic work demands disciplined integration. Airframe signature, sensor separation, line spacing, terrain following and base-station control all affect the dataset.

Service brief

Delivered in Malawi

Scope before aircraft.

Drone Solutions Malawi helps exploration and geophysical teams plan and execute UAV magnetic surveys in terrain where ground coverage may be slow or difficult. We start with the geological objective and target scale, then establish a practical acquisition design, sensor arrangement, line orientation, tie lines, clearance and quality-control procedure. Specialist interpretation can be scoped separately with appropriately qualified geophysicists.

Working method

How the assignment takes shape.

Each stage leaves a decision trail—from the initial brief through field execution and handover.

01

Design for the target

The expected target depth and orientation inform line direction, spacing, terrain clearance and the survey boundary.

02

Control magnetic noise

Sensor placement, airframe suitability, compass checks, base-station monitoring and test lines are reviewed before production flying.

03

Acquire and quality-check

Coverage, altitude, line deviation, diurnal variation and data continuity are monitored so gaps can be addressed while the crew is still on site.

Outputs

What can be included.

The final scope is written around the mission and the output your team will use. Typical components include:

Survey design and flight planRaw magnetic and positioning dataBase-station records where scopedQuality-control and line coverage reportLevelled or gridded data where specifiedGeophysical interpretation by separate scope

System fit

Platforms selected for the work.

Availability, payload compatibility and the final operating configuration are confirmed during consultation.

Practical limitsPower lines, vehicles, fences, buildings, ferrous ground objects and the aircraft itself can contaminate magnetic measurements.Very steep terrain, dense obstacles and required ground clearance may limit achievable line geometry.Data acquisition and geological interpretation are distinct scopes; neither guarantees a mineral discovery.

Plan the next step

Describe the target before specifying the grid.

Share the licence or survey boundary, available geology, target depth, preferred line spacing, terrain information and required data format.

Aircraft, payload and service availability may change. Flight operations remain subject to site conditions, the approved operating scope and applicable Malawi aviation requirements. Manufacturer performance figures are not service guarantees.
