Greenpatrol uses GNSS signals to navigate the robot. The use of GALILEO signals, with its larger bandwidth and its different carriers, on top of GPS and GLONASS, will enable better accuracy of positioning inside the greenhouse. Specially the stronger E-signals from Galileo are used to be able to navigate inside the greenhouses.
Galileo is Europe’s Global Satellite Navigation System (GNSS), providing improved positioning and timing information. Until December 2017, GNSS users have had to depend on non-civilian American GPS or Russian GLONASS signals. With Galileo, users now have a new, reliable alternative that, unlike these other programmes, remains under civilian control. As of December 2017, 22 of the planned 30 active satellites are in orbit. The next launch, which will bring the system to operational completion, is planned in mid 2018.
