- The new glass nano-satellite is created in the SPC "SPP"
As part of the program GLONASS JSC "Scientific and Production Corporation" Precision Instrument Systems "(JSC" SPC "SPP") has begun production of a new modification of the spherical glass autonomous nano-satellite. His predecessor — nano-satellite "BLITZ", was designed and built enterprise solutions in the interest of scientific and applied problems of space geodesy, geodynamics and calibration of laser range finders.
At the same time, it emphasizes the company's press service has been achieved unprecedented accuracy of 0.1 mm. September 21, 2009 simultaneously with nano-satellite spacecraft "Meteor-M" was launched into near-circular orbit with an altitude of about 830 km. "BLITZ" included in the list for the observation of laser stations with one of the highest priorities was successfully used the Russian network of laser stations and the International Laser Ranging Service (ILRS). Orbit the satellite has created the basis for a technological breakthrough in improving the instruments of the Russian and global network of satellite laser ranging to achieve sub-millimeter accuracy, which opens up entirely new possibilities in the study of problems of geodynamics, requiring precise measurements. Traditionally used for the purpose of satellites equipped with separate laser ranging corner reflectors that because of the spread of time leads to disturbance of up to several centimeters in determining the distance to the center of mass of the satellite. "BLITZ" — nanosatellite full central symmetry with the error bind the results of laser range measurements to the center of mass of the satellite is less than 0.1 mm, which allows for sub-millimeter positioning accuracy for scientific and applied problems of geodynamics, space geodesy and global navigation. The principle of operation is based on a nano-satellite spherical refractive effects in Luneburg lens. Nano-satellite was designed as an optical design of two cemented meniscus glass glued on monolithic glass bowl. On the outer surface of one of the meniscus — a mirror reflection coating. In January 2013, the satellite was lost, as expected, due to a collision with a small fragment of uncataloged debris. As a result of collision with nano-satellite "BLITZ" changed the orbit, the speed of rotation around its own center of mass, the orientation of the axis of rotation, more than 500 000 times decreased reflectivity, which is not allowed to use it as a target for laser ranging. Flight of the world's first glass of "BLITZ", first of all, wearing a technological nature and fully confirmed the correctness of the proposed innovative solutions for the creation of nano-satellites on the basis of geodetic spherical lens reflectors with almost zero "error" goal for precision distance measurements. According to the specialists of JSC "SPC" SPP "nanosatellites subsequent series" BLITZ "necessary to ensure high-precision coordinate GLONASS, it is advisable to run into higher orbits.
