amsatdl received and decoded Tianwen-1 telemetry again on March 18, 2026.

GeneralCapabilityValue 4.0Mar 18, 2026RT by @AJ_FI: Yesterday @amsatdl received and decoded again telemetry from Tianwen-1. I have done an updated plot of the orbital parameters with the new state vector telemetry. This shows that there have been no manoeuvres during the 3 months in which we haven't seen any signals. pic.
