The light weight dual frequency on board GNSS system for sUAVs was first conceptualized in September 2011 when we were once again frustrated by the lack of vision of proprietary VTOL UAS manufacturers whom we could not convince of the advantages of on board dual frequency GNSS in sUAS mapping applications. Hence we decided to take the development of this cost saving feature in our own hands and built a universal, affordable, hot-exchangeable, dual frequency GNSS V-Map (shown above on a modified Steadidrone) receiver weighing less than 130g (antenna mounting and cables included) and running at 20Hz.
Shown below in photos dating back to 2012 the platform independent V-Map system is mounted on the Aibot X6 copter from Aibotix GmbH and on an md4-1000 from Microdrones GmbH. It can be mounted on fixed wing platforms as well.
Use the V-map system
• in the air for GNSS supported SfM mapping,
• as a spatial reference back-bone in hydrographic surveying
• as well as in conventional terrestrial kinematic base-rover surveying as shown below
The V-Map system professionalizes small, modern, geo-spatial sensor platforms such as UAVs, remotely controlled autonomous boats and land vehicles. It empowers small mapping operations all over the world to make maps and geo-spatial products of professional quality. Equipped with an accurate event marker the V-Map system produces high precision camera exposure positions on dynamic platforms. The standard 1PPS port provides precision time tagging for hybrid surveying and data fusion applications. Additional ports for streaming RTCM and NMEA sentences can be furnished on request.
