Gam Ma - high pressure installation - high-voltage grounded converter installation for inducted electric lighting without galvanic elements. An analogue of a foreign company, developed in the 50s and 60s in the USSR.
The gamma is used to display the functions of lines and curves representing the direction and speed of movement of objects, people, animals, the movement of any means (for example, cars, etc.) along time coordinates (seconds, minutes, hours, days, months) and their locations on an arbitrary map for visual timing of mobility and speed in a given square. The main function of Gamma is to display physical speed on an electronic map.
