- output of navigation parameters (by way of electric signals) for indication and to coupling systems;
- generation of control signals for execution of horizontal navigation of airplane.
Equipment CH-3307M provides:
- automatic, continuous, in real time scale, during the stop and flight, in any spot on the globe, definition by signals from SNS GLONASS/GPS of:
- coordinates of airplane position,
- geodesic altitude of airplane (in direction of normal to the surface of geoid),
- components of the vector of ground speed of airplane (Vj, Vl, Vн),
- course angle and ground speed,
- indication of current coordinates on display and transmission of these coordinates to external customers;
- receipt and renewal of miscellanies of SNS GLONASS и GPS;
- input and storage of coordinates of 900 users’ points, up to 20 flight plans inclusive;
- input, storage, use and indication of navigation database;
- forming and output of analogue and digital electric signals.
Additional opportunities of the equipment CH-3307M compared to other modifications of the equipment CH-3307:
- color graphic display, an increase in the information field by 4-8 times;
- display of the flight route on the background of the underlying surface (electronic map);
- use of navigation databases (NDB);
- improving ergonomics in terms of the input of route point, routes and control of the equipment;
- an increase in the rate of solution of the navigation problem (10 Hz instead of 1 Hz);
