Impact of GPS Interference on Time Synchronization of DVB-T Transmitters

Table 1

Sources of timing errors in GPS.

Source of error	Timing error
User clock bias	10–50 ns
Receiver noise	<1 ns
Residual satellite clock error	<7 ns
Residual of broadcast ephemeris	<7 ns
Residual of tropospheric delay	0.3–2 ns
Residual of ionospheric delay	3–15 ns
