Claim:
1. A hub device for performing time synchronization in a satellite network, the satellite network including the hub device, a remote device and a satellite, the hub device comprising: a hub real time clock (RTC) counter that is time synchronized to a master clock; a hub network clock reference (NCR) counter that is continuously driven by a hub clock oscillator having a relatively high precision; processing circuitry that periodically generates a time packet, the time packet including a hub RTC value of the hub RTC counter and a hub NCR value of the hub NCR counter; and a transmitter that transmits, via the satellite, the generated time packet to the remote device to synchronize a remote RTC counter with the hub RTC counter based on the hub RTC value and the hub NCR value in the generated time packet.
