At the moment, low security is the main obstacle to the widespread use of drones. In many ways, the problems associated with accurate landing in places with limited zones. Until now, manufacturers and system developers continue to use manual control - as an opportunity to adjust the landing in those places where the accuracy of receiving GPS signals is limited. Existing systems do not provide reliable results in various conditions. Some do not work in low light, other systems have limited range and accuracy of determining the landing site. And in general, the existing systems are very unstable in gusting wind conditions, as a result of which the drone has to perform sharp maneuvers. That is why we decided to develop a system that will solve all these issues. Our main task is to make the operation of unmanned aerial vehicles simple and safe.

We made the system as light and easy as possible. The on-board unit of the system has dimensions of 21x41x1 (mm) and weighs less than 10 grams. The ground block is not much more - 63x38x20 (mm) with a weight of less than 50 grams. Such a form factor will allow you to easily integrate both a ground unit into the landing pad and an onboard module on your drone. The system does not take up much space on board and allows you to easily install your additional equipment. The body is made of lightweight and durable metal that helps protect components from mechanical damage during operation. The light indication on the ground module makes it easy to assess its current status and readiness to accompany your drone to the landing site.

The small size and the presence of several alternative interfaces allows integrating the landing system into almost all existing autopilots. For the user, I2C, UART and CAN interface are available through which the drone can get full information about the current state of the system. A simple protocol will make it possible to connect autopilot as quickly as possible at the software level. Each module has a USB port for device diagnostics as well as simple installation of fresh software updates.

The system does not require additional sensors for its work. The onboard unit can independently determine the distance to the landing site. This allows landing on platforms that are significantly higher than the environment and information about the distance to the ground is significantly different from the actual height to the landing platform. The on-board receiver also does not require data from the drone inertial system and all changes do not depend on the inclination and speed of movement of the aircraft - this allows you to work stably with strong gusts of wind when the angular position of the drone changes very quickly. Low power consumption (less than 0.3 watts for the onboard module and 1.1 watts for the ground module) allows the system to operate for a long time from a small power source. It is possible to easily change the approach path (to make it not vertical but at an angle) - this allows the vehicle to land in places where there is an obstacle on one side (for example, a balcony).
