Preliminary tests of precision landing modules
Preliminart tests were carried out to develop a precision landing system.
With the sole usage of the GNSS satellite navigation system, landing errors exceeded the accepted requirements. After using the RTK mode in satellite navigation, a landing precision of 10-15 cm was obtained. When using an additional optical module, the landing accuracy was between 5 – 10 cm. The preliminary tests confirmed the legitimacy of using the optical module in the designated precision landing system.
