OFO IKI / KKVO

Test models of the TsTK-140 and TsMK-70 digital aerial cameras have been developed and manufactured in cooperation with юNO “Cosmos-NT” based on space technologies.

The TsTK-140 camera has been designed for black & white topographic stereo imaging. Large swath (22,000 pixels) and highly detailed imagery make it possible to use aircraft altitude ceiling at maximum.

The TsTK-140 camera is based on AFA TE-140 camera optical unit. Electronic unit with linear CCD and a unit for precision determination of absolute orientation angular elements are used instead of film pack.

The TsMK-70 camera provides for aerial imaging in four spectral bands simultaneously (RGB and near-IR).

Imaging control and image data flow registration is fulfilled by the onboard computer. This allows to control image acquisition in real time.

Image data characteristics and advantages

The coordinate and time reference system (KKVO) has been developed for determination of s/c spatial orientation in real time as well as orbital parameters with a required frequency of spatial orientation and s/c postioning updatement.

The data obtained by the system is used for s/c flight control and coordinate referencing of the remote sensing data.

The first experiment on the KKVO design processing will be conducted onboard the "Meteor-M" #1 s/c.

The "Meteor-M" coordinate&clock system includes two measuring instruments – BOKZ-M star tracker and GPS/GLONASS receiver.

The future coordinate&clock referencing system is being developed in cooperation with the Russian Institute of Radionavigation and Time. This sytem will include in addition to GPS receivers and star trackers with a frequency of attitude determination more than 10 Hz and built-in angular velocity MEMS-sensor, the optcal solar sensors, accelerometers and CPU.
