description The invention discloses a satellite network route updating method and device. The method comprises the following steps: acquiring a target data packet, a current forwarding satellite and a preset first routing table; selecting a forwarding satellite with the minimum routing value in a preset first routing table as a first routing value, and selecting a next forwarding satellite; sending the target data packet to a next forwarding satellite, and obtaining time information of sending the target data packet to the next forwarding satellite; based on the time information, calculating a target routing cost value of sending the target data packet to a next forwarding satellite; acquiring a preset second routing table corresponding to the next forwarding satellite, and selecting the forwarding satellite with the minimum routing value in the preset second routing table as a second routing value; and obtaining a target routing calculation value based on the first routing value, the second routing value and the target
