The Earth-spacecraft system (ME > > msat) is described within the framework of Newtonian mechanics. In our paper we elaborate some specific applications. The equations of motion are solved for the case of resonance and synchronism between the wave and the orbital frequency for first order perturbations. The case of synchronism leads to the strongest effect. If a satellite is used for detection of gravitational waves, a drag-free system should be considered to detach the detector from disturbances present in the Earth orbit. The oscillations which are caused by gravitational waves from binary systems will be calculated for ideal conditions. The range of detectable gravitational waves (approximately 10^-5 to 10^-4 Hz) depend on the orbit radius. Close binary systems like 44 iBoo should be considered for these form of detection due to necessary observation time of 10^7 sec and amplitude of 10^-7 mm. This method - to use a Earth-artificial satellite orbit as a gravitational wave detector - fits between the methods using pulsar timing observations (approximately 10^-8 to 10^-6 Hz) and Doppler tracking of interplanetary spacecraft (approximately 10^-5 to $10^-2 Hz).
