Miniature sensor and absolute orientation measurements – Research Paper Example

Miniature sensor and absolute orientation measurements Overview Today, it is no longer a security that technology has grown beyond the manufacturingof personal computers for use in homes and offices. Indeed, technological advancement has been extended farther in all spheres of human lives that make use of machines of all kind. The creation of sensors is one aspect of technology that has made the use of other forms of machines more complicated: yet better functioning. Previously, a lot of people did not see the ‘technology’ in the function of machines like still cameras and plotters. Today, the thinking is different because these machines have been fused with the power of technology to do much more than we initially knew of them to do. Miniature sensors have been embraced even in the use of microfluidic devices. But as miniature sensors become more and important, one question that should never cease is asking which of the sensors are the best in the market and which of them offers the best value money can buy. This question brings to discussion VN-100 Rugged, which has been described as “a miniature high performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS)” (Vector Nav, 2011). Arguments to the effect that the VN-100 Rugged is the best to be used for the purpose of developing a miniature sensor in comparison with other sensors shall be taken from the lines of performance, durability and maintenance.
Performance
The level of performance of a device of this nature comes from a lot of factors such as different types of functioning sub-components built in the device. Indeed, technology permits that sensors, no matter how small they may be should be embedded with a lot of functionalities that will make the scope of use in the development of miniature sensor broader. As far as performance and functionality is concerned, we are told that the VN-100 Rugged has high performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). The functions of IMUs alone are known to include the measurement and reporting velocity, gravitational force and orientation on crafts. This makes the performance and functions of the VN-100 Rugged very versatile. The Attitude Heading Reference System also gives attitude, yaw and axes information for aircraft. Apart from these two features, the VN-100 Rugged “combines 3-axis accelerometers, 3-axis gyros, and 3-axis magnetic sensors as well as a 32-bit processor into a lightweight robust aluminum enclosure” (Vector Nav, 2011) thereby making its performance and functions very broad and widespread.
Durability and reliability
The VN-100 Rugged can be trusted on longevity and reliability. Though stocked with complex operations and specifications such as the ability to compute and output a real-time drift free 3D orientation solution that is continuous over the complete 360 degrees of motion (Vector Nav, 2011), the device can be trusted to work for long if not forever. This is one difference between the NV-100 Rugged and other modern sensor devices. It has been argued that as sensors get more complicated in their functions and performance, their reliability and durability begins to drop (Gagner, 2001). The NV-100 Rugged has however been proofed to work above this criticism. Built in a very compact way to contain all the specifications discussed, the NV-100 Rugged has dimensions of 33 x 26 x 9mm; power of 70mA at 5V and mass of 15g. The advantage of the light weight is that the device is less fragile and less prone to breaking apart when it drops on the ground. The device can withstand other conditions such as temperature, fire and moist as “each of the 9 MEMS sensors inside every VN-100 is uniquely characterized by inspecting its output across a wide range of different accelerations, angular rates, varying magnetic fields and temperature” (Vector Nav, 2011). What is more, in the construction of the device, care is given to ensure that errors in operations are not just reduced but eliminated.
Maintenance
The setting of use of the VN-100 Rugged makes maintenance very necessary for any buyer to worry about. In aerospace grade Kalmar filter for instance, there is every justification to believe that the need to maintain the device will arise. Gagner (2001) writes on existing sensors and condemns how they have been created not be me maintainable. He laments that most often than not, manufacturers are not conscious to advancing their inventions with how the devices they create can be maintained in case faults set in. he is even quick to blame this on intentional practices saying that some manufacturers take out the feature of maintenance so that own a device crashes, new purchases will have to be made. Contrary to this accusation of other sensors, we are told that manufacturers of the VN-100 Rugged have over 50 years of combined experience in the field of inertial navigation and therefore there are always in house engeers and staff who are familiar with the most difficult and complex problems of integrating MEMS devices (Vector Nav, 2011). For this reason, provisions are adequately made to meet all clients at their points of need when it comes to maintaining devices they purchase to measure absolute orientation in 3-space with sub-milli-radian accuracy.
Conclusion
Very little remains to be said than the fact that the VN-100 Rugged is the best option based on the factors discussed. It is an outfit that has been trusted for years to deliver and they continue to live by their hard earned reputation.
