Dronesurvey Asia is an Official Dealer, Greater China for Emlid precision RTK GNSS base station receivers and modules for surveying mapping and navigation. Emlid has built a solid reputation with affordable RTK GNSS solutions that are renowned not only for their reliability and precision, but also their ease of use.
The Reach RS2 is the flagship product; a multi-band RTK GNSS receiver with centimetre accuracy, the RS2 achieves an accurate location fix almost instantly, and maintains its performance in even the most challenging conditions.
The Reach RS2 also includes a cellular modem for seamless connectivity with NTRIP services, and a built-in LoRa radio for acquiring RTK corrections in remote areas. The ReachView app for iOS and Android that comes with the RS2, is used to collect and stakeout points and easily control and monitor all features of the system.

The Reach RS+ is a cost-effective single band GNSS base station receiver. The Reach RS+ is designed to work in all kinds of harsh conditions; dense forests, mountains, frost, heat and water (IP67-rated), Reach RS+ can handle them all.
Together with the ReachView App, it’s easy to collect and stake out points, and control all features including setting up a base station, logging RINEX data, and configuring NMEA output. Plus we make file export easy; open them in GIS or CAD software like AutoCAD, ArcGIS, QGIS, and others.

Reach M2/M+ GNSS Modules for UAVs
The Reach GNSS modules for UAVs deliver centimetre-level accuracy in RTK and PPK, giving you precise aerial mapping with less Ground Control Points (GCPs) — an important consideration in some of Hong Kong’s rougher terrain.
Camera synchronisation is important: when a drone is flying at 20 m/s and GPS works at only 5 Hz, you’ll have position readings only every 4m or so — this is not enough for precise georeferencing. In addition, theres always a delay between the trigger and the actual moment the photo is taken.
The Reach M2/M+ Modules solve this problem by connecting directly to the camera hot shoe, ensuring precise synchronisation with the shutter. The time and coordinates of each photo are logged in less than a microsecond. You can further eliminate the need for GCPs, or use GCPs just to check your accuracy.
The Reach M2 Module is designed to work with the Reach RS2 base station receiver. It provides robust performance and quick initialisation, allowing work on long baselines, with RTK up to 60km and PPK up to 100km. The M2 has multi-band frequencies, and a RINEX logging update rate up to 20Hz.
The Reach M+ Module is designed to work with the Reach RS+ base station receiver. The M+ is an optimal choice for shorter baselines, with RTK up to 10km and PPK up to 20km. This is a single-band module with a RINEX logging update rate up to 14Hz..
