Gravity
AGP-GRAV – a proprietary state of art strapdown-based airborne gravity system
Special development for gravity airborne geophysical surveys based on high performance inertial navigation system
Advantages
- Two sets of sensors
- Precise measurements with wider dynamic range
- High reliable performance in high turbulence
- Aircraft-independent operations (fixed-wing, helicopters, UAV)
- Lack of the gyro-stabilized unit
- Low residual drift
- Improved thermal stabilization
- Simple and fully autonomous operation
- Сutting-edge post-processing software
The main issues to be solved:
Mapping sedimentary basins and structural controls for oil and gas exploration program
(cost effectively placing seismic surveys)
Identification and mapping of fault blocks, igneous intrusives Identification and mapping of fault blocks, igneous intrusives
Mapping and modeling objects with anomalous densities

AGP-GRAV uses two triads of accelerometers to improve the accuracy of the data
AGP-GRAV has dual circuit temperature control system that allows the gravimeter to be used over a wide temperature range and further reduces zero-point drift
AGP-GRAV is specially calibrated to take into account all parameters of the sensors
Multi-parameter survey that acquire maximum of geophysical parameters simultaneously
Example of problems solved
Structural framework and hydrocarbon potential estimation
