Radar interferometer measurements of space debris using the Evpatoria RT-70 transmitter

Crowded Space: A Review on Radar Measurements for Space Debris Monitoring and Tracking

“…The ability of the Ukrainian transmitter RT-70 to operate in a space debris radar scenario has briefly been discussed earlier in Section 3. The RT-70 is a 70 m dual reflector parabolic antenna located in Evpatoria (Ukraine) that can operate in the frequency spectrum from VHF to X-band [67,68]. It is able to transmit a CW signal with a peak power of about 200 kW (at 5 GHz) [67,68].…”

“…The RT-70 is a 70 m dual reflector parabolic antenna located in Evpatoria (Ukraine) that can operate in the frequency spectrum from VHF to X-band [67,68]. It is able to transmit a CW signal with a peak power of about 200 kW (at 5 GHz) [67,68]. Investigations on the suitability of the powerful transmitter in a bistatic configuration for debris measurements were conducted in the form of four trial experiments between 2001 and 2003 performed in Geostationary, Highly Elliptical and Medium Earth Orbits (GEO, HEO and MEO) [68].…”

VLBI studies at the Radiophysical Research Institute

“…The experiments on development of the VLBI radar method have been performed since 2001 on the basis of the LFVN network only [48,[70][71][72][73][74][75][76][77]. The data interpretation (determination of parameters of the object orbits) is performed at the M. V. Keldysh Institute of Applied Mechanics of the Russian Academy of Sciences.…”

“…The Ballistic Centre of the M. V. Keldysh Institute of Applied Mechanics of the Russian Academy of Sciences refines the orbital parameters of the studied objects. The results of the a posteriori estimation of the accuracy of determining the elements of the orbit of the "Kosmos-1366" satellite are shown in Table 1 [74,75]. The radial velocity of the "Kosmos-1366" satellite in the geostationary orbit was estimated from the measurements of the Doppler frequency shift on the baselines Evpatoriya-Urumchi and Evpatoriya-Medvezhyi Ozera and were processed jointly with optical measurements of the satellite right ascension and declination.…”

Plans for development of Pulkovo cooperation of optical observers

“…INTRODUCTION from the New Independent States of the FSU (INTAS) and the The works on creation of new optical network for space Ministry of Education and Science of the Russian Federation. debris observations were started in 2001 in order to support the Also three important events occasioned in 2004: (i) the program of the radar research of the high-orbit space objects Ussuriysk observatory on Far East joined to the project with with the 6 cm transmitter of the 70-m antenna dish (RT-70) in 40-cm double Zeiss astrograph equipped with ST-6 CCD Evpatoria, Crimea of Ukraine [2]. camera; (ii) trial searching observations of the faint space The first GEO object observations aimed to improve the efemerides of radar targets were carried out in April 2001 at Pulkovo observatory using the 10-cm AKD telescope with ST-8 CCD-camera.…”
