Static Antenna Stabilization / 靜態天線穩定
When it comes to maritime communication or train communication, stabilized
antennas are key – they have to remain pointed at the satellite in order to
ensure a constant flow of data, with regulations stating that an accuracy better
than 0.5 is essential to maintain an active transmission.
These demands highlight the need for precise, highly accurate measurements for
altitude and angular rate. This means that the antenna has to receive input from
at least one orientation sensor in order to respond to changes in vehicle
orientation.
Mechanical Sensors
As a low cost yet highly accurate gyro technology, vibrating gyros for
measurement of Coriolis force are ideal solutions for platform stabilization
applications. Micro-machined devices based on silicon or as they are known as
MEMS are becoming less costly and increasingly capable. Colibrys MEMS
accelerometers are ideal devices used
in many platform stabilization application. Our new GS/GM1000 vibrating gyros
offer best in class noise figures, which renders this device an ideal choice for
many platform stabilization applications.
The Colibrys solution
Our recommended sensor for this application is the GM1000
Gyro Module, a packaged version of the GS1000 housed in a miniature
container with all its electronic components. Each GM1000 gyro is
factory-calibrated and compensated for temperature effects in order to provide
high-accuracy differential analogue output voltage or a 24-bit digital output
through RS422 interface. Powered by a single 5 to 18Vdc supply for seamless
integration, this unit has already proven operational in such demanding
applications as remotely controlled weapon stations, camera platform
stabilization, electro-optical platform stabilization with MTBF of 1.000.000
hours.
The GM1000 is the ideal gyro for weapons platform stabilization as it
demonstrates excellent bias over temperature performance, unmatched performance
in presence of vibration, low power consumption and rugged durability. Light
weight, low-noise and excellent bias renders this device an ideal choice for
platform stabilization applications.
