RTK is built into the Matrice 4E as standard, no separate module to fit, rated at 1cm + 1ppm horizontal and 1.5cm + 1ppm vertical once FIX is achieved.
Position the unit in open ground with a clear view of the sky over both the survey area and the takeoff point.
RTK Fix accuracy describes how precisely the aircraft knows its own antenna position, not how precisely that translates to the ground point a pixel represents.
The M4E's three cameras are fixed to the airframe, there's no bay to swap a different sensor in.
Known coordinates and averaged in FIX both produce a base position accurate to survey control.
Setting up a D-RTK 3 as a base station is a one-time job; using it well on an actual survey or mapping site is a different skill, reading the correction status during a flight, knowing when FIX has genuinely dropped out rather than just fluctuating, and understanding what limits how many aircraft it…
An Emlid Reach receiver serves two separate functions on a DJI mapping job. As a base station, it broadcasts RTCM3 corrections over NTRIP to the aircraft's RTK module, giving it a local correction source independent of network coverage.
Every row above the camera line reads the same. The positioning engine did not change between the two models; the housing added two lenses.
