Mining
The mining industry encounters numerous challenges that necessitate the use of innovative technologies to conduct operations safely and efficiently. Among these challenges is the need to navigate and operate underground without depending on GNSS signals, which remain inaccessible in subterranean environments. At Exail, we are confident that our technologies, developed through years of experience in the naval, land defense and subsea operations domains, are best suited to address these challenges. Serving both surface and subsurface mining operations, Exail establishes itself as a dependable partner that delivers unparalleled navigation
performance and data stability for all mining applications
Inertial solutions for mining applications
Mine survey
Highly accurate data
For high-accuracy mining survey applications, the performance and repeatability of measurements are crucial. Phins E offers ultimate performance in GNSS-denied environments with a heading accuracy of up to 0.05° seclat without GNSS, enabling the collection of precise data for mapping and assessing mining sites.
Low power consumption
With the advent of new sensor technology such as Atlans 9-AHRS, power consumption has been significantly reduced. This lower power requirement translates to extended battery life and increased endurance, making them ideal for integration into mobile survey tools.


Real-time monitoring
Exail navigation systems provide real-time data on the device’s orientation and motion. When integrated into survey tools, this real-time monitoring capability enables operators to track their movements and adjust their positioning promptly, ensuring accurate survey results.
Enhanced post-processed data
Data collected by Exail INS can be post-processed using Exail’s dedicated Delph INS software. Reference points, GNSS data, or additional sensors such as DMI (Distance Measurement Instrument) can be utilized to compute a precise and optimal trajectory. The forward-backward algorithm significantly enhances performance for non-real-time applications.
Underground mining
Accurate underground navigation
Based on FOG technology, Exail’s AHRS and INS are able to operate in GNSS-denied underground mining settings, offering undisturbed navigation at all times. Real-time and accurate tracking of equipment and vehicle positions enables:
- optimal route planning
- equipment and personal safety by avoiding potential hazards (underground cavities, unstable terrain…)
High-precision drilling
Exail AHRS provide accurate data on drilling machines’ attitude and heading, enabling precise drilling operations. Thanks to these data, operators that drill machines reach the desired location accurately and drill the holes with the required precision while maintaining the machine stability. This is crucial for efficient and effective mining operations.

Continuous operations and high
productivity levels
For some mining machines, alignment time can result in significant costs due to operational interruptions. In the cases when electrical devices must be grounded, Exail AHRS or INS need to reinitiate their alignment process. Phins E INS offers rapid startup alignment, as quick as 3 minutes, which results in time and cost savings on the field, enhancing overall efficiency. In addition, Phins E’s capability to operate autonomously, without reliance on external signals, guarantees continuous functionality and maintains high productivity levels, even in GNSS-denied areas.
High resistance to shock and vibrations
Exail systems are engineered to endure the challenging conditions found in mining settings, including vibrations, dust, and extreme temperatures. Robust and highly resistant to rugged environments, it features temperature tolerance ranging from -32°C to +71°C, enabling reliable performance under the harshest operational circumstances.
