Overview
1) The Radio telemetry system is based on 3DR Radio system and 100% compatible.
2) It’s designed as an open source Xbee replacement radio set, offering a lower price, longer range (approx one mile) and superior performance to Xbee radios. It’s available in 915Mhz and 433Mhz; and in the following configurations: serial board (for the air) and USB (for the ground).
3) The system provides a full-duplex link using HopeRF’s HM-TRP modules running custom, open source firmware. Interface to the module is via standard 5V-tolerant TTL serial / FTDI USB serial.
4) Firmware upgrades and configuration are fully supported in the APM Mission Planner. Configuration is also possible through the 3DR Radio configurator and AT commands.
5) Features:
– Small size and light weight
– Available in 433MHz variants
– Receiver sensitivity to -121 dBm
– Transmit power up to 20dBm (100mW)
– Transparent serial link
– Air data rates up to 250kbps
– MAVLink protocol framing and status reporting
– Frequency hopping spread spectrum (FHSS)
– Adaptive time division multiplexing (TDM)
– Support for LBT and AFA
– Configurable duty cycle
– Built in error correcting code (can correct up to 25% data bit errors)
– Demonstrated range of several kilometers with a small omni antenna
– Can be used with a bi-directional amplifier for even more range
– Open source firmware
– AT commands for radio configuration
– RT commands for remote radio configuration
– Adaptive flow control when used with APM
– Based on the HopeRF HM-TRP radio module, featuring an SiLabs Si1000 RF microcontroller.
