TwinGyro™ ‒ Ultra-rugged Dual Gyro Technology

Inertial Sensing's latest innovation in gyro survey technology delivering QA/QC compliant data twice as fast as a regular gyro.

All new versions of Inertial Sensing gyros are capable of running in both standard multi-shot mode as well as the new fast continuous survey mode. Survey data from a continuous survey can easily be reprocessed to any required station interval.

Survey security The TwinGyro™ combines two independent survey systems in one instrument. Where a standard tool completes one survey, the TwinGyro™ delivers two independent surveys.

Independent backup The system contains a built-in backup - the TwinGyro™ can be run in single gyro mode and continue operating even if one system has been damaged.

High rate capability Each system is equipped with an extra roll axis gyro covering rates up to 1,000 deg/s. These high rate gyros accurately track rapid angular changes caused by wireline torque release or angular shock from the rotary unit when tripping rods.

High accuracy ‒ ultra-rugged The TwinGyro™ is based on the electronics of the SlimGyro™ and delivers the same high accuracy. The mechanical design is based on the rugged isGyro™ system.

Low power consumption The TwinGyro™ has a power consumption of only 0.4 W. The system can also be used in single mode to preserve power. An additional delayed start mode allows the system to be initialized in 5 mW sleep mode to wake up for surveying after a pre-set time.
