Objects in Geostationary Transfer Orbit (GTO) result from the launch of satellites in geostationary orbit. There are close to 200 GTO, most of them third stage rockets used for transferring satellites from low Earth orbit to geostationary orbit. By crossing the low Earth orbit region at high speed more than twice a day, they represent a hazard for low Earth orbiting satellites. The situation in GTO is described and the danger presented by these objects for the low Earth satellite population is stressed. The source and accuracy of tracking data is indicated and the effect of orbital perturbations on the orbit evolution is recalled. First attempts to determine ballistic coefficients are outlined and the accuracy of reentry prediction is discussed. The range of expected lifetimes are given.
