The paper shows the results of the research concerning the determination of aircraft positioning accuracy with the use of Global Positioning System and European Geostationary Navigation Overlay Service.Experimental flights were conducted in 2013,in south-eastern part of Poland.A precise aircraft position was determined with the use of dual frequency geodetic Topcon receivers with centimeter accuracy.The reference position was confronted with the data logged by two navigation receivers - Thales MobileMapper and Septentrio AsteRx2i HDC,IMU enhanced GPS/GLONASS dual-frequency receiver,which was used for the calculation of an accurate reference trajectory as well as for testing both the EGNOS accuracy and the protection level in autonomous and EGNOS mode.As a result of the research it turns out,that EGNOS does not meet requirements for SBAS (Satellite Based Augmentation Service) operations in this area.

越来越多的西方人开始喜欢中国菜。那么，在美国营养学家的眼中，中国菜是否健康呢？近日，美国《赫芬顿邮报》刊登了美国饮食营养协会的新闻发言人安吉莉亚·吉恩对中国菜的点评。 １．水煮毛豆热量不低。水煮毛豆富含膳食纤维，但有些餐馆会在煮好后放入热油中泡一会儿，这就让它的热量骤增。 ２．豆豉酱口味、营养都不差，且含糖量低。 ３．五彩虾片不适合做开胃菜。虾片是由虾汁加上淀粉油炸而成的，每一小把炸虾片就含
