  ^{Measured in an unobstructed outdoor environment free of interference. The above data shows the farthest communication range for one-way, non-return flights under each standard. Always pay attention to RTH reminders in the app during your flight. The relay station should be placed in a elevated, unobstructed location to ensure clear communication between the remote controller and the aircraft.}

• Max Transmission Distance in Relay Station Mode (unobstructed, with interference)

• Strong interference: City centers, approx. 1.5-5 km
  Medium interference: Suburban areas, approx. 5-15 km
  Micro interference: Remote areas/seasides, approx. 15-25 km

  ^{Data is tested under FCC standards in unobstructed environments of typical interference. Only to serve as a reference and provides no guarantee as to the actual flight distance.}

• Max Transmission Distance in Relay Station Mode(obstructed, with interference)

• Low Interference and Obstructed by Buildings: approx. 0-0.5 km
  Low Interference and Obstructed by Trees: approx. 0.5-3 km

• Antenna

• OcuSync 4 directional antennas× 4, 2T4R

  ^{The antenna uses a standard reverse polarity SMA connector.}

Electrical Properties

• Power

• Relay Station: 14.5 W (max power consumption without heating; max 36.5 W with heating)
  Base Station: 7 W
  Rover Station: 6.2 W

• Supported Power Adapter

• USB PD 3.0 protocol, output voltage 9V to 15V adapter (e.g., DJI 65W Portable Charger)

  ^{When using a non-recommended charger, such as a charger with 5V-output, the D-RTK 3 Base Station can be charged only after powering off.}

• Power Output Port

• USB Type-C

• Operating Time (Under Normal Temperature)*

• Relay Station: 4 hrs
  Base Station：7 hrs
  Rover Station: 10 hrs

  ^{* Battery performance may decrease in low temperatures; it is recommended to use power adapters that support the USB PD 3.0 protocol.}

• Battery

• LiPo
  Capacity: 6500 mAh
  Energy: 46.8 Wh

Physical Characteristics

• Operating Temperature

• -20° to 55°C (-4° to 131°F)

  <sup>1. In normal temperature environments, charging power will be limited if the device shell temperature exceeds 48°C (118.4°F). Full power charging will resume after cooling.
  2. After storage/use in low temperatures, the device needs to be brought to a normal temperature environment and allowed to warm up until the internal battery temperature is >0°C (32°F) before charging.
  3. After storage/use in high temperatures, the device needs to be brought to a normal temperature environment and allowed to cool down until the internal battery temperature is <45°C (113°F) before charging.</sup>
