| 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. |
