Emlid Reach M2 Multiband RTK GNSS

The Emlid Reach M2 Multiband RTK GNSS Module for UAV mapping provides positioning with centimeter accuracy in RTK and PPK with less GCPs. Features: GNSS:  GPS/QZSS, GLONASS L1, L2; BeiDou B1, B2; Galileo E1, E5 Long range radio:  External LoRa radio module: 868/915 MHz, range up to 8 km. (sold separately) Multiband Baseline up to 100km in PPK Comes with the Emlid Flow app for iOS and Android PPK Mapping with Centimeter Accuracy | Use Fewer GCPs Why camera synchronization is so important:  Usually 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 will have position readings only each 4 m, which is not suitable for precise georeferencing. In addition, there is always a delay between the trigger and the actual moment the photo is taken. Emlid Reach eliminates the delay:  Reach solves the problem of positioning by connecting directly to the camera hot shoe port, which is s
