How often does the CTU transmit?
The CTU transmits every 75 seconds but the information is only received at the ground station when there is a satellite positioned overhead. Because the satellites are a polar orbiting LEO constellation, the coverage ranges from constant at the poles to about every 1.5 hours at the equator. How often you receive an update depends on the location of your cargo but you should expect reports on average every 1-1.5 hours.
