Octopus ISR Systems, a division of UAV Factory Ltd., has released a precision geo-pointing feature for its miniature Epsilon series of gyro-stabilized gimbals. The feature, Precision Geo-Lock, combines a GPS-aided inertial navigation system (GPS/INS) with dedicated software algorithms and payload operator software. Octopus ISR Systems’ Epsilon 140z gyro-stabilized gimbal. To guarantee the successful implementation of the Precision Geo-Lock feature, UAV Factory partnered with VectorNav Technologies of Dallas. Precision Geo-Lock provides the user with highly accurate target geo-location, range-to-target, as well as Geo-Lock functionality and moving map user interface. Equipping a miniature airborne gimbal with precision geo-location presents a multitude of challenges. The gimbal operates in a high vibration environment and is subjected to high accelerations and extreme ranges in temperature. In addition, small size and low power consumption are significant factors for miniature gyro-stabilized gimbals which are often used in unmanned aircraft. The attitude solutions commonly available onboard unmanned aircraft typically do not present a reliable solution. “Traditionally, small gyro-stabilized gimbals use an external heading source to estimate the geo-location of the target,” said UAV Factory CEO Konstantins Popiks. “Onboard the unmanned aircraft, the attitude data is usually supplied by an autopilot, and the estimate accuracy is not very precise due to the nature of low-cost sensors used in miniature autopilots. Miniature autopilots simply do not need the precise heading data required by the gimbal, and as a result, the heading error generates large geo-location errors and provides little to no use for the unmanned aircraft operator. There are also additional errors due to misalignment of the gimbal and autopilot, as these are separate subsystems mounted in different locations on individual soft vibration mounts.” VectorNav’s VN-200 surface mount GPS/INS. To enable the Geo-Lock feature, an external GPS/INS needed to be integrated, and such a GPS/INS needed to provide a high level of accuracy. “Today, the state- of-the-art miniature gyro-stabilized gimbals have a narrow field of view of less than 1.3 degrees; therefore, the accuracy of the pointing should be significantly better than 1.3 degrees to prevent the target pointing location from going out of the video frame,” Popiks said. VectorNav is a developer and manufacturer of high-performance inertial navigation systems using the latest in MEMS sensor and GPS/GNSS technology. VectorNav’s industrial series line of inertial navigation solutions provide small, light and low-power consumption solutions in the industrial-grade inertial navigation performance category (attitude accuracy 0.1-0.3). “VectorNav’s VN-200 was the only product on the market that offered a high-level of performance but small enough form factor that it could be integrated directly into the optical bench of the gimbal,” Popiks said. “When the product delivered that level of accuracy despite the high vibrations, accelerations and temperature fluctuations of our application the choice was obvious.” UAV Factory’s Precision Geo-Lock provides better than 0.3 degree accuracy and is plug-and-play, so the customer can install the Epsilon gimbal and get accurate results on any platform and in a high-vibration environment. Epsilon gyro-stabilized turrets will be available with both VectorNav’s VN-200 single GPS-based INS solution, as well as the VN-300 dual GPS-based INS. A single GPS/INS solution is suitable for dynamic platforms such as manned and unmanned aircraft, while dual GPS/INS is a necessity for platforms with low dynamics, such as aerostats, ships and helicopters.
