Nowadays, the MEO region is mostly populated with satellites of the Global Navigation Satallite SystemsNAVSTAR GPS and GLONASS. Satellites were launched since 1978 (GPS) and 1982 (GLONASS),respectively. Due to the replacement of old satellites and the deployment of new systems like Galileoand Compass the number of satellites will increase. As a consequence, the number of space debris willalso increase.The search for space debris objects in the MEO region at the AIUB is performed with the small aperturetelescope ZimSMART, located in Zimmerwald, 10km South of Bern (Switzerland). To minimise theprocessing steps, the tracklets (sets of at least three observations belonging together) from the MEOsurveys are analysed in the same processing pipeline as those from GEO surveys. MEO and GEO surveysare observed alternating during one night.The surveys are performed by scanning the orbital planes of former as well as of active GNSS satellites.The survey strategy consists of tracking pseudo-objects with equidistant spacing in an orbital plane. So,a homogeneous coverage of the orbital plane is guaranteed.We will present survey results of the investigated orbital planes. Between April 2011 and February 2012,orbital planes of four satellites were observed: GIOVE-A, MOLNIYA 1??93, NAVSTAR 23 of NAVSTARGPS and COSMOS 2442 of GLONASS.
