In order to assure its customers the highest level of quality of its products, the inertial technology development division of GEM elettronica has obtained a wide number of quality certifications. Other than the following product certifications, GEM elettronica’s guidance, navigation e positioning sensors are compliant with the most demanding international military specifications.
Therefore, inertial navigation products engineered by PRANS lab can assure the highest reliability and the best performances in civilian and commercial applications as well as in defence and military missions.


Inertial Test Facility

GEM elettronica in house high performance Inertial Test Facility is the most comprehensive laboratory in Italy to perform calibrations, testing and validation of the Interferometer Fiber Optic Gyroscope (IFOG) and Inertial Systems and provide test report books and calibration certificates.
The Fiber Optic Gyroscopes are calibrated using advanced rate table instruments providing precise angular rate output. In addition to the primary focus of inertial system calibrations, the laboratory has different areas capabilities covering a broad range of other test and measurement including thermal testing, climatic testing, shock, linear and angular vibration testing.
All Fiber Optic Gyrocompasses manufactured by GEM elettronica are tested in a specific department that checks the quality of the production by simulating extreme environmental conditions and the most harsh events (vibrations, shocks, temperature variations, etc.)
Every Gyrocompass, besides the demanding tests, is calibrated in GEM elettronica before being installed on the end user platform. This permits an immediate starting of its functioning once the sensor is plugged in.

EMI-EMC Testing

Motion Simulators

Precision rate and orientation inputs allow accurate calibration and testing for inertial sensors. Continuous acceleration and angular rate can be independently controlled on each axis, while the integrated environmental chamber with programmable temperature provides additional testing capability.

Test Tables

Two axis motion simulators are mainly used to run simplified calibration and test routines along the assembly process of inertial sensor to improve overall throughput of the manufacturing plant.

Single-Axis Rate Tables

Rate Tables

Accuracy and dynamic range of single axis gyroscopes are deeply tested before actual assembly on final product.

Corrosion Testing


Product qualification requires extended test of performances while operating under heavy vibration or mechanical shock. Digital control of the shaker provides a wide range of possible mechanical stress, data recording and analysis.

Product Assurance test facilities

Climatic Testing

Climatic Testing

Temperature – humidity chamber simulates environmental effects on a device subjected to atmospheric conditions on a range from -45°C to +90°C. Chambers are computer controlled and are able to generate complex temperature and humidity profiles.

Corrosion Testing

Corrosion Testing

Salt fog chamber simulates exposure of test specimen to extremely harsh environment for extended periods of time and provides corrosion testing according to most demanding civilian and military specification.

EMI / EMC Testing

Anechoic chamber allows accurate measure of Electro Magnetic Interference emitted by units under test and is currently used for EMI / EMC testing according to most demanding civilian and military specification.
