Command and telemetry radio modem RМ-16М
Applications
Command telemetry radio modem RМ-16М is intended for two-side duplex data exchange between the UAV and ground control unit on a distance up to 100 km.Tasks performed by the instrument/device
- Commands transmission from ground control unit to the aircraft
- Telemetry data transmission from aircraft to the ground control unit.
Major application properties of the instrument/device
- Transparent data transmission channel from standard interfaces RS-232, RS-422, RS-485
- Possibility to create several virtual data transmission channels from different interfaces. For example, separate channels for autopilot and payload
- Network structure, possibility of information retransmission
- Availability to collect information from various sources (for example, from the payload)
Key features and properties
- Small-sized device intended for half-duplex data exchange with an UAV
- Possibility to create wireless self-organizing network (ad-hoc-network)
- Signal specter extension mode for communication distance increasing
- Built-in power amplifier – 1 W
