Introduction

The D-RTK 2 High Precision GNSS Mobile Station is a high-precision satellite signal receiver that supports four global satellite navigation systems: GPS, BEIDOU, GLONASS, and Galileo with 11-band satellite signal* reception. Its built-in OCUSYNCTM, LAN, and 4G data transmission links ensure uninterrupted, stable data transmission under a variety of application scenarios. The D-RTK 2 Mobile Station can be used as an RTK mobile base station to achieve centimeter-level positioning accuracy of an aircraft equipped with a DJI RTK positioning system (such as Agras T20, T16, MG-1P RTK, Phantom 4 RTK, P4 Multispectral, MATRICETM 300 RTK, or Matrice 210 RTK V2). Its functions are uncompromised even in environments with strong magnetic interference, for example, near high-voltage power lines or metal structures. The D-RTK 2 Mobile Station can also be used as a handheld mapping device to achieve enhanced precision in point positioning during surveying and mapping, or lofting and other engineering applications. In addition, the D-RTK 2 Mobile Station can be used as a stationary RTK base station to quickly build network RTK services**.

• Refer to the Specifications for details.
  ** Supported later. DJI only provides technical services, users must comply with the local laws, regulations and requirements for building network RTK services.

Using with M300 RTK or M210 RTK V2 Aircraft
Power on the mobile station, and make sure that it is linked to the aircraft or remote controller. Launch the DJI Pilot app and follow the on-screen steps for activation.

Setup
When used as a mobile base station, choose an open area to set up the D-RTK 2 Mobile Station. Mark the location and align the center of the tripod with the mark to ensure that the D-RTK 2 Mobile Station can be replaced at the same location.

1. Unfold the tripod, stretch the three retractable legs to the desired length, and then tighten each of the three knobs. Ensure that the bubble of the bubble level on the mount base is located within the black circle (viewed from the top of the bubble level vertically) while keeping the tripod secure.

2. Insert the extension rod into the tripod and tighten the sleeve on the tripod. Then attach the D-RTK 2 body onto the extension rod and tighten the lock nut on the D-RTK 2 body. Ensure that the bubble of the bubble level on the D-RTK 2 is located within the black circle (viewed from the top of the bubble level vertically).

Caution

• DO NOT change the position or angle of the tripod or the D-RTK 2 Mobile Station after the tripod has been leveled, or else it should be readjusted.

• The setup environment requires a wild field of vision. Ensure that there are no obstructions
  (trees, buildings) within the zone more than a 15° angel above the horizontal plane of the
  D-RTK 2 antenna to prevent the GNSS signals from being absorbed or blocked.

• The setup location should be at least 200 m away from high-power radio emission sources
  (such as television stations, microwave stations, etc.) and at least 50 m away from highvoltage transmission lines to avoid electromagnetic interference to GNSS signals.

• The setup location should be away from large-area waters or objects that strongly interfere
  with satellite signal reception to reduce multipath effects.

Usage
The available operating modes vary depending on the products used with the D-RTK 2 Mobile Station. Select the corresponding operating mode according to the product in use and follow the instructions below.

Instructions
Operating Mode 1/4

1. Lift the extension rod in the tripod to adjust the D-RTK 2 Mobile Station to the desired height and tighten the sleeve.
