After the launch of our first satellite (assuming a single ground station), the maximum latency should be 16 hours for devices deployed around the equator. The closer to the poles, the shorter the latency will be.
Due to the polar sun synchronous orbit of our satellites, each satellite we will pass the poles 16 times per day (every 1.5 hours) and the equator twice a day (every 12 hours). This means that with one satellite operational, the travel time of a message is as follows:
- A message is submitted to the Hiberband modem. The modem will await the next pass of the satellite, which can take up to 12 hours.
- The satellite has received the packet and will keep it in store until it can forward it to the ground station, this can take up to 4 hours.
- Once the ground station has received a packet, it will be almost immediately available through the Hiber back-end.
