TELEVISION CAMERA TVC
Measurement principle
One of the tasks of «Poperedzhennja» (WARNING) program is observation
ionospheres emission in visible and infrared spectrum range from satellites board
looking-for heralds of earthquakes. Its needs solution satellites orientation problem for
defining location of sources of ionospheric emissions above Earths surface with necessary
accuracy. There is possibility to define orientation of photometric devices by using TV
images of star background.
The CCD TV camera is designed for recording of images of star sky, Earth limb and adjoining part of Earth surface to fix
the orbit point coordinates during the measurements by FAGOT and SICH-F devices. An additional task of TVC is
receiving of large-scaled picture of ionospheric glow distribution.
Experiment configuration
CTV consists of the camera unit CU and the processing unit PU. CU consist of the input lens, filters wheel, CCD frame
transfer area array sensors, preamplifier, double correlation sample, amplifier, temperature control. In PU are 12 bit ADC,
4 x 256K x 12 bit video memory, control logic and interface RS485.
Main characteristics of the instrument
Operation
Orientation of the TVC optic axis: parallel to axis I of the FAGOT instrument.
The experiment has next modes of operation: recording of images of the star sky and Earth limb; storing of the data and their transmission; testing of device.
The data transmission is carried out using:
