Until a few years ago, drones with a GNSS receiver on board cost tens of thousands of dollars. This solution was available only to large companies. Over the past year, small and affordable GNSS receivers, budget base stations and open source processing software have appeared on the market. By combining these solutions with reliable drones such as DJI Phantom 4 Pro, Geoscan 101/201, Fixar 005, Diam 6, we created an inexpensive tool for a surveyors, cartographers, cadastral engineers, mine surveyors, etc. At Aerostream you can upgrade your drone turn it into a survey instrument.

Upgrade includes:

• Installation of L1 Emlid Reach M+ or L1\L2 Emlid Reach M2
• Installation of a camera shutter to geodetic receiver synchronization system. Surveying with a quadcopter at 100 meters altitude, it provides 3-5 cm horizontal and vertical accuracy without ground reference points. Surveying with a fixed wing, horizontal and vertical accuracy of 10 cm is achievable.
• Camera and lens upgrade, when using Sony RX1 and Sony Alpha series 
• External quick release receiver and antenna mount for quadcopter, and built in installation for a fixed wing
• Camera calibration, camera calibration parameters and camera to antenna offsets
• Custom software for image georeference files production
• Survey data processing and photogrammetric processing manual (for Agisoft Metashape)
