RTK GNSS module for precise navigation and UAV mapping without GCP

— Reach M+
— USB cable
— USB-OTG cable
— JST-GH 6-pin to jumper pin cable
— JST-GH 5-pin to jumper pin cable

Two receivers or NTRIP are required for centimeter accuracy

Description

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

ings are not suitable for precise georeferencing. Also, there is always a delay between the trigger and the actual moment the photo is takensuch read

.

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.
