Reach M+

RTK positioning for navigation

Reach calculates real-time coordinates with centimeter accuracy
and streams them in NMEA or binary format to your device
over UART, Bluetooth or Wi-Fi.

PPK for UAV mapping.
Centimeter accuracy without GCP

Reach module logs precise tracks and the exact moment
when each photo is taken.

Why camera synchronization is so important?

Usually autopilot triggers the camera and records the coordinate it has at the moment.

When the drone is flying at 20m/s and GPS works at 5Hz, that means your autopilot will have position readings only each 4m.

While enough for navigation such readings are not suitable for precise georeferencing.

Also, there is always a delay between the trigger and the actual moment the photo is taken.

Reach module solves this by directly connecting to the camera hot shoe port which is synced to the shutter.

The time of each photo is logged with a resolution of less than a microsecond.

Connect Reach to a hot shoe port on a camera                                                                     Fly a drone, Reach will record photo events 

Every time a photo is taken camera produces a pulse on a flash                                               Reach captures flash sync pulses with sub-microsecond resolution and
