PPK mapping with centimeter accurateness. Use fewer GCPs

Why camera synchronization is and then important

Normally autopilot triggers the camera and records the coordinate it has at that moment. When the drone is flying at 20 m/s and GPS works at 5 Hz, that means your autopilot volition have position readings only each 4 k, which is not suitable for precise georeferencing. In addition, there is e'er a delay between the trigger and the actual moment the photo is taken.

Achieve eliminates the delay

Reach solves the problem of positioning by connecting directly to the camera hot shoe port, which is synced with the shutter. The fourth dimension and coordinates of each photograph are logged with a resolution of less than a microsecond. This method allows GCPs to be used merely to cheque your accuracy.

1. Connect Reach to a hot shoe port on a camera

Every time a photo is taken camera produces a pulse on a flash hot-shoe connector which is synced to a shutter opening.

2. Fly a drone, Achieve will record photo events

Accomplish captures wink sync pulses with sub-microsecond resolution and stores them in a raw data RINEX log in the internal memory.

3. Download logs from Reach and base station

After the flight, get the RINEX logs from your airborne Accomplish module and a base station (Attain RS, CORS or another receiver).

4. Process logs and get a file with geotags of photos

Procedure RINEX files using free RTKLIB software. The produced file with precise coordinates of the photos can be used for georeferencing.

NTRIP or some other Reach every bit a base station

To calculate centimeter-precise coordinates in PPK and RTK, Reach needs corrections from a base of operations station. It could be either another Accomplish receiver or an NTRIP service. VRS is as well supported.

Compatibility

Reach M2 and M+ work seamlessly with other Achieve receivers over any link and are uniform with whatever other receiver that supports RTCM3 and NTRIP.

Comes
with ReachView 3 app

The most user-friendly software for data collection that is bachelor both for Android and iOS. Supports thousands of coordinate systems and is translated into multiple languages. With ReachView three, you can command all the features of Reach receivers, such as setting up a base station, logging RINEX information, and configuring NMEA output.

Photographic camera
command

Attain can trigger cameras as well as register events. The issue mark feature is a must for aerial mapping as it allows the precise time when the shutter was activated to be registered.

Elementary log

3DroneMapping completes PPK trials with the boilerplate zero mean error in all axes

Luke Wijnberg, 3DroneMapping

As a brief synopsis of the results, the maximum departure of points was no more than 0.09m in all axes. This is an incredible event given the fact that the average pixel size of the resulting imagery was 0.045m. The average hateful error in all axes is merely few mm!

Tuffwing gets 4cm precision without GCPs with Emlid Reach RTK

Brian Christal, Tuffwing

Tuffwing recently performed integration of Emlid Reach RTK to enable precision maps to be fabricated without the use of GCPs. The system has been benchmarked by comparing a direct georeferenced model with a fix of GCPs, used solely for error detection purposes. The lateral RMS error achieved is merely 4cm co-ordinate to the Pix4D quality report.

Event38 integrates Emlid Reach and starts providing a gear up-to-go PPK mapping solution

Jeff Taylor, Event38

In this case study, we produced an orthomosaic in the Drone Data Management System™ with two.45cm horizontal and 5.08cm vertical RMSE, as compared with a survey-grade GPS on the ground.
