Grif-17 Relay aerial repeater

Grif-17 Relay is an aerial repeater on a 17-inch platform designed to expand the area of stable communication and video transmission beyond the direct line of sight of ground infrastructure.

With a long position hold time of up to 50 minutes, day/night operation mode, optical stabilization, and support for separate control and video transmission channels, the Grif-17 Relay provides a reliable “air knee” for operation at an extended distance.

Advantages of our repeater

Expanding the communication area

The drone rises above ground obstacles and provides a more stable radio horizon, allowing communication to be maintained where ground infrastructure no longer works directly.

Working out of direct visibility

Grif-17 Relay creates an aerial communication "knee" that helps transmit control and video signals in difficult terrain, building conditions, or obstacles.

Long-term position holding

Hover time of up to approximately 50 minutes allows you to stay at a given point for a long time and maintain a stable communication channel.

Main areas of application

Grif-17 Relay is used to extend the radio communication and video transmission area in conditions where ground infrastructure has limited coverage or direct visibility between equipment is impossible. The repeater rises into the air, increases the radio horizon and creates a stable intermediate communication link for operation in remote areas, in difficult terrain, among buildings or in places with natural obstacles.

The main areas of application include monitoring of large areas, video channel support at remote sites, search and rescue operations, emergency and crisis situations, field technical tasks, work in industrial, agricultural, forest and hard-to-reach areas. Grif-17 Relay can also be used as a temporary aerial communication infrastructure when it is necessary to quickly provide a stable communication channel without installing masts, towers or complex ground equipment.

Frequently asked questions

Why do I need Grif-17 Relay?

The Grif-17 Relay is used as an aerial repeater to extend radio and video coverage. It rises above ground obstacles and helps provide more stable communications where line-of-sight between equipment is limited.
How long can a repeater stay in the air?

In position hold mode, the Grif-17 Relay can operate for up to approximately 50 minutes, and the total flight time, including transit to the point, position hold, and return, is up to approximately 55 minutes.
Can I change the hold point while working?

Yes, the operator can adjust the hold point using the right stick of the remote control without leaving hover mode. This allows you to adapt the position of the repeater to the current operating conditions.
What happens when the battery is low?

The system provides for automatic landing when the battery reaches a specified charge level. This increases operational safety and reduces the risk of equipment loss.
