Аnnotation: The paper deals with some features of modern techniques for gravity field research using the moving objects and the position of aero-gravimetric research is discussed among them. The features of creating a mobile gravimetric laboratory on the basis of an aircraft with high autonomy and duration of the flight to perform work on remote territories and water areas are described. We consider in detail our experience of creating an aircraft laboratory on the basis of the AN-30D and AN-26BRL production aircrafts. The composition of gravimetric and navigation equipment has been substantiated, the need for installing additional devices for heat and vibration protection, backup power lines, and additional communication facilities has been shown, and the device and operation of airborne gravimetric complexes based on different principles of operation have been described. A description of the method of performing aerogravimetric survey and features of its implementation is given. The basic concepts of the software packages for express and office processing of gravimetric and navigation information obtained both on board aircraft and at the base (ground) stations of the GPS or GLONASS satellite navigation systems are outlined. The methods for taking into account amendments for airborne gravimetric complexes with different operating principles are discussed.
