Abstract:
1. A method for selecting a ground station for communication with an aerial vehicle, the method comprising: receiving at an aerial vehicle one or more messages from one or more ground stations; storing one or more signal strength values corresponding to the one or more received messages in a data structure for each respective one or more ground stations received during a predefined time period; updating the data structure for each of the one or more ground stations; calculating an average of the signal strength values stored in each data structure to determine an average signal strength; comparing the average signal strength of each of the one or more ground stations; selecting which ground station the aerial vehicle is to communicate with based on predefined criteria; and adjusting the number of signal strength values stored in the data structures based on comparing the message traffic density for each of the one or more ground stations with a message traffic density level, wherein adjusting the number of signal strength values comprises:
